Description

[0001]
[Industrial application fields]
The present invention relates to a billing error prevention method in a medical fee billing process in a medical office system.
[0002]
With the recent advancement and complexity of medical contents, medical remuneration request processing is also becoming more complex. For example, in addition to social insurance and national health insurance established by national medical management organizations, there are welfare measures systems unique to prefectures that are local governments, and the treatment of medical compensation claims varies depending on the department. Each medical institution registers and references the necessary contraindication check content independently.
[0003]
In this case, the treatment fee request process in the medical office system is mixed with the contraindication check content set by the national medical management institution and the contraindication check content registered independently at each medical institution. It is necessary to be able to check necessary contraindications selectively every time.
[0004]
In addition, in the contraindication check, if “medical practice A” and “medical practice B” cannot be calculated on the same day, there is a need for a medical institution to calculate using the higher clinical practice code. In the check, it is necessary to determine which is given priority for each medical practice code.
[0005]
In addition, the contraindication check when performing the above-described medical fee processing may be performed by batch processing on a monthly basis depending on the medical institution. Therefore, the contraindication check when the medical fee remuneration process is performed needs to have a choice between the real time or the monthly batch process when the medical practice occurs.
[0006]
[Prior art]
FIG. 6 is a diagram for explaining a conventional method for checking contraindications in medical practice. FIG. 6 (a) shows a data format in the medical practice master, and FIG. 6 (b) shows conventional system management information. The format of the file is shown, and FIG. 7 is a flowchart showing the conventional medical fee claim processing.
[0007]
First of all, in the medical office system, the medical contents for each patient for one month are described in a receipt (medical remuneration statement), and the daily medical contents are stored in order to make an insurance claim to the insurance organization. To enter.
[0008]
Mistakes in the operator's input mistakes, insufficient input, etc. cause many profits and losses for the medical institution. Conventionally, the information of the medical practice code (6) in the medical practice master format shown in FIG. Then, referring to the system management information file 1 in the format shown in FIG. 6 (b), check the contraindications of the medical practice, that is, check the medical code that would be double billed at the same time to prevent billing mistakes. It is out.
[0009]
Each information of the medical practice code {circle around (6)} stored for each patient stored in the medical practice master file shown in FIG.
[0010]
Code: A key (KEY) item that serves as record control information for managing the medical practice master itself, and is represented by, for example, a 5-digit number.
Abbreviation: Accounting input made for each patient is entered using this abbreviation code.
Diagnosis Zone: An information item that finely defines the location on the receipt form where the medical treatment is to be counted.
Medical practice name: The name of the medical practice is stored.
Score: Stores the insurance score for each medical practice set by the national medical management organization (Ministry of Health and Welfare).
Warning number: It is information that can display a warning message for preventing omission of billing when inputting medical practice.
Others: In addition to the above information, there is information necessary for calculating insurance points.
[0011]
FIG. 6B shows a system management information file necessary for performing a medical practice and a contraindication check of the medical practice.
[0012]
Every medical institution in the country has a billing error check that is carried out in a fixed manner within the medical office system in order to check billing errors and omissions that occur in common. This is a check of the medical practice code and the contraindication of the medical practice, which is a check of the medical code that is double-requested at the reception. Conventionally, the contraindication of the medical practice code that cannot be calculated simultaneously in the same month is performed.
[0013]
The system management information file 1 stores information shown in FIG. That is,
Key (KEY) part: Stores a code of “medical practice master” {refer to FIG. 6 (a)} to be checked for contraindications.
[0014]
Codes (1) to (15): The “medical practice master” code that cannot be calculated in the same month as the medical code indicated by the key (KEY) part is stored.
[0015]
The medical practice indicated by the codes indicated by the codes (1) to (15) in this system management information file includes the same clinical practice as the medical practice indicated by the clinical code indicated by the key (KEY) part. Therefore, if these medical codes (1) to (15) have already been input, it will be input that it will be double billed if a new medical code indicated by the key (KEY) part is input. It is designed to prevent mistakes.
[0016]
FIG. 7 shows an outline of the medical fee billing process when generating an accounting card for creating the receipt. This processing is performed with reference to the information of the medical practice code {circle around (6)} for each patient in the medical practice master of FIG. 6 (a) and the system management information file 1 shown in FIG. 6 (b). explain.
[0017]
The accounting card file, which is the data used when creating the receipt, stores information on the medical practice code (6) in the format shown in FIG. 6 (a) together with the input date for each patient. However, in the medical fee claim process described below, it is processed on a monthly basis.
[0018]
First, an operator inputs information on a medical practice code (6) of a patient in the format of the medical practice master shown in FIG. 6 (a). (See processing step 100)
Whether or not the medical practice code {corresponding to the KEY part code 10 of the system management information file 1 in FIG. 6 (b)} exists in the KEY part 10 of the system management information file 1 is searched. If the system management information file 1 does not exist, it is determined that it is not the medical treatment code (6) subject to the accounting process, and nothing is done and the process returns to the processing step 100, but if the corresponding system management information file 1 exists When the accounting card file 2 to be described later is searched and the same medical practice code (6) exists in the accounting card file 2 in the month, the corresponding medical practice code (6) is stored in the system management information file 1. It is checked whether or not it exists in the contraindication check target code (1) to (15) 11. Although it is registered in the accounting card file 2 as an unacceptable medical practice, if it exists in the contraindication check target codes (1) to (15) 11 of the system management information file 1, a contraindication check is necessary. If there is a medical practice code (6) and this medical practice information code (6) is registered in the accounting card file, a double charge will be made. Therefore, “Clinical practice code A” will be “medical practice code B”. The message “Cannot be calculated the same month” is displayed to prevent operator mistakes (see steps 101 to 104).
[0019]
[Problems to be solved by the invention]
In the conventional medical fee processing, it is possible to check the contraindications of the medical practice code within the same month, but it is not possible to check the contraindications within the same day, so it is necessary to search all accounting card files 2 constructed on a monthly basis. There was a problem that it took a long time to search.
[0020]
In addition to social insurance and national health insurance established by the national medical management organization, there are welfare measures systems that are unique to the prefecture, which is a local government, and the treatment of medical fee reimbursement processing varies depending on the department. However, even if each medical institution (user) tries to register and refer to the necessary contraindication check contents independently, there is a problem that the user cannot register and refer to the necessary contraindication check contents.
[0021]
In view of the above-mentioned conventional drawbacks, the present invention provides a medical office system and a billing error prevention method capable of more accurately preventing a billing error in a medical office system according to the operation mode of each medical institution. It is intended.
[0022]
[Means for Solving the Problems]
In the medical office system, refer to the system management information file when generating the accounting card file by entering the medical practice code necessary for issuing a receipt, and prevent the input of medical practice codes that cannot be calculated simultaneously. When checking contraindications,
In the key part of the system management information file, a serial number management flag is provided for distinguishing whether the system management information file is a fixed determination check content in the medical office system or a new user's own check content,
When the system management information file is updated, it is selectively updated based on the serial number management flag.
[0023]
A process identification flag for distinguishing whether the contraindication check is performed by batch processing or real-time processing is provided in the input medical practice code, and the contraindication check is performed by the processing indicated by the process identification flag.
[0024]
[Action]
The system management information file according to the present invention preferentially calculates the check target code indicated by the key part of the system management information file for each of the contraindication check codes, or prioritizes the contraindication target codes of the respective code information. A type management flag is provided for distinguishing whether to calculate automatically, and when the type management flag is “0”, the check target code is preferentially calculated, and the priority code in the contraindication check message is, for example, Display on the left side.
[0025]
In addition, when a medical treatment code entered in the medical practice master format is provided with a processing identification flag and the processing identification flag is “0”, a contraindication check is performed when the medical accounting card file is created. If the process identification flag is “1”, when creating the medical accounting card file, the accounting card file is constructed without checking the contraindications, and the month the month is separately created at the end of the month. By reading out the accounting card file and performing the contraindication check, it becomes possible to flexibly cope with the processing mode requested by the user.
[0026]
【Example】
FIG. 1 is an explanatory diagram of the principle of the present invention. The present invention is achieved by a medical office system and billing error prevention method configured as follows.
[0027]
(1) In the medical office system, it is not possible to calculate at the same time referring to the system management information file 1 when the accounting card file 2 is generated by inputting the medical treatment code (6) necessary for issuing a receipt. A method of suppressing the input of the medical practice code (6),
In the system management information file 1 key (KEY) part 10 is provided with a division management flag {circle over (1)} for distinguishing between the same month contraindication check and the same day contraindication check,
A contraindication check corresponding to the value of the category management flag (1) is performed.
[0028]
(2) Each code information {code (1) to (15)} 11 of the contraindication check of the system management information file 1 is preferentially checked by the check target code indicated by the key (KEY) portion 10 of the system management information file 1 And a type management flag {circle over (2)} that distinguishes whether to preferentially calculate with the contraindication target code of each code information 11 above,
When performing the contraindication check of item 1, the code indicated by the value of the type management flag {circle around (2)} is preferentially set as a calculation target.
[0029]
(3) In the key (KEY) part 10 of the system management information file, a serial number management flag for distinguishing whether the system management information file is a determination check content fixed to the medical office system or a check content of a new user himself ▲ 3 ▼
When the system management information file 1 is updated, the system management information file 1 is selectively updated based on the serial number management flag (3).
[0030]
(4) When generating the system management information file 1 based on the contraindication check table (4), when the code information 11 for the contraindication check is input, the contraindication check indicated by the type management flag (2) is performed. For this purpose, a system management information file 1a is generated in which each code information 11 of the contraindication check is used as a key (KYE) section 10.
[0031]
(5) A processing identification flag {circle over (5)} is provided in the input medical practice code {circle around (6)} for distinguishing whether the contraindication check described in the above items 1 to 4 is performed by batch processing or real time processing. And
A contraindication check is performed in the process indicated by the process identification flag (5).
[0032]
1 to 3 are diagrams for explaining the principle of the present invention. FIG. 1 shows an example of the structure of a system management information file. FIG. 2 shows an example of registration of a contraindication check table (4) by a user. Shows an example of generating a system management information file. In the billing error prevention method according to the present invention, first,
1) In the system management information file 1 according to the present invention, the KEY section 10 is provided with a division management flag {circle around (1)} for distinguishing between the same month contraindication check and the same day contraindication check, and the division management flag {overscore (1)} is “0”. ", The contraindication check is performed on the same month, and the contraindication check is performed on the same day when the classification management flag (1) is" 1 ".
[0033]
By performing a contraindication check with “medical practice code (6) + α (category management flag) (1)”, a conventional “Same month contraindication check” and a new “Same day contraindication check” can be performed. Performing the same day contraindication check, it is only necessary to search for registered clinical practice codes of the same date for the medical practice code 6 to be entered on the accounting card file 2 and speed up the search process. Effect is obtained.
[0034]
In this case, when the category management flag (1) is “0”, a message ““ Clinical practice code A ”cannot be calculated the same month as“ Clinical practice code B ”” is displayed.
When the division management flag (1) is “1”, a message “The medical treatment code A cannot be calculated on the same day as the medical treatment code B” is displayed. The value can be used to distinguish between the same month and the same day.
[0035]
2) Further, the system management information file 1 according to the present invention includes the check target codes indicated by the key (KEY) portion 10 of the system management information file 1 in the contraindication check codes (1) to (15) 11, respectively. Is provided with a type management flag {circle over (2)} that distinguishes whether to preferentially calculate the contraindication target code of each code information 11, and when the type management flag {circle around (2)} is “0”, The check target code is preferentially calculated, and the priority code is displayed, for example, on the left side in the contraindication check message.
"Example of contraindication check message when type management flag (2) = 0"
““ Psychiatric visiting nursing / instruction fee ”(check target code) cannot be calculated the same day as“ Nursing home visiting nursing fee / instruction fee ”(incompatible check code),
"Example of contraindication check message when type management flag (2) = 1"
““ Nursing home nursing fee / guidance fee ”(code for contraindication check) cannot be calculated the same day as“ Psychiatric nursing fee / guidance fee ”(check code)”.
[0036]
By providing such a function, as described above, “medical practice code A” and “medical practice code B” cannot be calculated on the same day, but “if any, the higher score is desired” In response to the needs of medical institution managers (users), the contraindication check message can have the meaning of the above priority calculation.
[0037]
3) As described above, the contents of the contraindication check are handled in the medical fee processing system of the present invention in view of the fact that the treatment fee request processing differs depending on the medical treatment code {circle around (6)}. In order to allow users to register, refer to, and change with the same record structure while keeping the contents of the contraindication check established by the traditional national health care management organization (Ministry of Health and Welfare), the contraindication check table (4) shown in Fig. 2 is used. Separately, the user simultaneously generates and, as shown in FIG. 1, the KEY section 10 of the system management information file 1 indicates whether the system management information file 1 is the content of the determination check fixed to the medical office system, or is new When the system management information file 1 is updated by providing a serial number management flag {circle over (3)} that distinguishes whether the user's own check contents or not, the serial number management flag Lug ▲ 3 ▼ on the basis, so as to selectively update.
[0038]
When the serial number management flag (3) is “0”, the contraindication judgment check fixed to the medical office system is performed. When the serial number management flag (3) is “1”, the contraindication judgment check set by the user is performed. And
[0039]
Then, the user can register and change only the contraindication check table (4) in which the serial number management flag (3) is “1”, so that the contraindication determination check table (4) fixed in the medical office system can be obtained. Make sure that a is not infringed.
[0040]
By adopting such a configuration, when the national medical management organization (Ministry of Health and Welfare) has changed the medical system, the manufacturer of the medical office system sets the serial number management flag (3) to “0”. By updating the corresponding contraindication check table {circle around (4)} a collectively, the contraindication check method can be updated without affecting the contraindication check table {circle around (4)} created by the user.
[0041]
4) In addition, in the contraindication check method of the present invention, not only a billing error check is performed when the medical practice code of the KEY section 10 of the system management information file 1 is input, but also the code (1) of the system management information file 1 (15) 11 The user registers the above-mentioned contraindication check table (4) so that a billing error check can be performed even when a medical practice code subject to incontinence check is input, and system management information of the contraindication check condition In order to prevent the user from registering the reverse pattern one by one when generating the record of the file 1, the medical office system uses the contraindication check table (4) generated by the user to set the contraindication check target code. A record of the system management information file 1a set in the KEY section 10 is generated.
[0042]
At this time, the processing shown in FIG. 3 is performed in order to protect the meaning of the type management flag {circle around (2)} on the message. That is,
a) The user himself / herself registers the contraindication check conditions according to “Contraindication check table” (4).
[0043]
b) Generate a record of “system management information file” 1 as instructed in a).
[0044]
c) A record of the “system management information file” 1a having the reverse pattern is generated inside the medical office system so that the user does not need to register the reverse pattern and generate the system information file 1.
[0045]
FIG. 3 (a) shows an example of the contraindication check table (4) registered by the user. In this example, the check target code is “08256” “psychiatric home-visit nursing / instruction fee”. Based on the table (4), the medical office system generates a record of the system management information file 1 shown in FIG. At this time, since the above-mentioned “type management flag” {circle around (2)} is “0”, the priority when requesting medical remuneration is: check target code (08256)> contraindication check target code (00101). The reverse pattern generated by the clerical system is shown in Fig. 3 (c).
The message “Check code (08256)> Contraindication check code (00101)” such as “Clinical action code“ 08256 ”cannot be calculated the same day as“ Clinical action code “00101” ”.” Here, the system By simply reversing the KEY part 10 of the information management file 1 and the contraindication check target codes (1) to (15) 11,
The message “Clinical practice code“ 00101 ”cannot be calculated on the same day as“ Clinical practice code “08256” ”.” From the message, the contraindication check target code (00101)> check target code (08256) Therefore, in the medical fee remuneration process of the present invention, the message when the type management flag (2) is changed from “0” to “1” and the medical practice code (00101) is input is
The message “" medical practice code “08256” ”cannot be calculated on the same day as“ medical practice code “00101” ”” is used.
[0046]
5) In the example described in 1) to 4) above, an explanation is given of an example in which a contraindication check is performed when an operator inputs a medical practice code (6) and creates an accounting card file 2, but a medical institution Depending on the (user), when entering the medical practice code (6), the contraindication check process may be performed as a batch process at the end of the month, especially without entering the contraindication check.
[0047]
Therefore, in the medical fee remuneration process of the present invention, as shown in FIG. 3 (d), a processing identification flag (5) is provided in the medical practice code (6) input in the format of the medical practice master. If the processing identification flag {circle over (5)} is “0”, a contraindication check is performed when the medical accounting card file 2 is created. If the processing identification flag {circle over (5)} is “1”, the medical accounting accounting is performed. When the card file 2 is created, without checking the contraindications, the accounting card file 2 is constructed, and at the end of the month, the created accounting card file 2 for that month is read out separately, and the above contraindications are made. By performing the check, it is possible to flexibly cope with the processing mode requested by the user.
[0048]
Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 3 are explanatory diagrams of the principle of the present invention, and FIGS. 4 and 5 are flowcharts showing an embodiment of the present invention.
[0049]
In the present invention, in the medical office system, referring to the system management information file 1 when the accounting card file 2 is generated by inputting the medical practice code (6) necessary for issuing a receipt, This is a method for suppressing the input of the medical practice code (6) that cannot be calculated, and the key (KEY) part 10 of the system management information file 1 has a category management flag (1) for distinguishing between the same month contraindication check and the same day contraindication check. ▼ and each code information {code (1) to (15)} 11 of the contraindication check of the system management information file 1 are preferentially checked by the check target code indicated by the key (KEY) portion 10 of the system management information file 1 Type management flag {circle over (2)} that distinguishes whether the calculation is to be performed preferentially or to be preferentially calculated based on the contraindicated codes of each code information 11 above, When performing the contraindication check, the system management information file includes a means for preferentially calculating the code indicated by the value of the type management flag {circle around (2)} and a key (KEY) portion 10 of the system management information file. A serial number management flag (3) for discriminating whether the check contents fixed to the medical office system or the new user's own check contents, and the serial number management flag (3) when updating the system management information file 1 When the code information 11 of the contraindication check is input when the system management information file 1 is generated based on the means for selectively updating based on the above and the contraindication check table (4) generated by the user, In order to perform the contraindication check indicated by the type management flag {circle over (2)}, each code information 11 of the contraindication check is a key (KYE) part 10. The system management information file 1 is generated. Further, a process identification flag (5) for distinguishing whether the contraindication check is performed in batch processing or real-time processing is added to the input medical practice code (6). The means for providing ▼ is a means necessary for carrying out the present invention. In addition, the same code | symbol has shown the same target object through all the figures.
[0050]
Hereinafter, the medical fee remuneration process according to the present invention will be described with reference to FIGS.
[0051]
First, the medical practice code (6) of the medical practice master is entered from the medical accounting screen for generating the accounting card file 2. {See processing step 200 in FIG. 4}
In the next processing step 200a, the process identification flag (5) of the present invention is seen. If the process identification flag (5) is “0”, the medical fee reimbursement process starts in real time. If the identification flag {circle over (5)} is “1”, it means batch processing, and without checking the contraindications, the medical treatment code {circle around (6)} is temporarily stored in the accounting card file 2 and the end of the month, etc. Then, the accounting card file 2 is read out, and the processing of the next processing steps 201 to 201 is performed by batch processing.
[0052]
In the processing step 201, the system management information file 1 is referred to based on the medical practice code (6) of the medical practice master, and if the corresponding medical practice code (6) does not exist in the KEY section 10, an accounting is performed. If it is not a medical treatment code to be processed, nothing is done and the processing returns to processing step 200. However, if the medical treatment code {circle around (6)} exists in the KEY section 10 of the system management information file 1, the next processing step Move to 203. {See processing steps 201 and 202 in FIG. 4}
When the category management flag (1) of the corresponding code in the system management information file 1 is “0”, the contraindication check target codes (1) to (15) 11 are viewed, and the same contraindication check target medical treatment is applied to each of the codes. If the activity code (6) is in the month of the accounting card file 2 or if the category management flag (1) of the corresponding code in the system management information file 1 is “1”, the accounting card file 2 Confirm that the same medical practice code (6) exists in the date of the month, and if it does not exist, it is not a contraindication check target code. If it exists, the type management flag (2) of the corresponding contraindication check target codes (1) to (15) 11 of the system management information file 1 is referred to, and the type management flag If the check (2) is “0”, the code to be checked will be preferentially calculated, ““ Check target code A ”cannot be calculated in the same month (or same day) as“ Contraindication check target code B ”” The system is arranged and the process proceeds to the next processing step 205. If the type management flag {circle over (2)} is “1”, it is assumed that the contraindication check target code is preferentially calculated, ““ Contraindication check target code B ”. "Cannot be calculated in the same month (or the same day) as" check target code A "", and proceeds to the next processing step 205. The above processing is the contraindication check target code (1) in the system management information file 1 ~ (15) Repeat for 11. {See processing steps 203 and 204 in FIG. 4}
In the next processing step 205, since the corresponding medical practice code cannot be calculated simultaneously on the same month or on the same month, a predetermined message is displayed on the screen of the accounting card, and the processing returns to the first processing step 200. The next medical practice code (6) is entered.
[0053]
The serial number management flag (3) for distinguishing whether the system management information file 1 is a fixed check content in the medical office system or a new user's own check content is particularly conscious in the medical fee processing. This is a management flag for the medical office system to perform management. Normally, the user registers only the contents of the system management information file 1 whose serial number management flag (3) is “1”. Can be changed.
[0054]
As described above, in the medical office system, the present invention refers to a system management information file that is necessary for issuing a receipt and that generates an accounting card by inputting a medical practice code, and cannot be calculated in the same month. This is a method for inhibiting the input of an action code, and a classification management flag {circle around (1)} is provided in the key (KEY) portion of the system management information file to distinguish between the same month contraindication check and the same day contraindication check. In addition, a type management flag {circle over (2)} for distinguishing whether the check target code is preferentially calculated or the contraindication target code is preferentially calculated is provided in each code information of the contraindication check of the system management information file. Also, in the key (KEY) portion of the system management information file, a serial number management flag (3) for distinguishing whether the system management information file is a fixed check content for the medical office system or a new user's own check content. There is a feature in the place where is provided.
[0055]
【The invention's effect】
As described above in detail, according to the medical office system and the billing error prevention processing method of the present invention, 1) billing errors can be prevented according to the operation mode of each medical institution. 2) The contraindication check for the same month and the same day can be performed by the category management flag (1) in the system management information file. If the contraindication check on the same day is performed, the specified date can be searched for the accounting card file, so that the medical fee request process can be speeded up. 3) With the type management flag (2) of the system management information file, the calculation priority condition in the message text can be specified, and the user's request can be flexibly handled. 4) With the serial number management flag (3) in the system management information file, it is possible to select whether the medical fee reimbursement process is to be fixed to the medical office system for each medical practice code or to be a user's own determination. Can flexibly cope with user-specific requirements. 5) The system management information file required for the contraindication check when the code for the contraindication check in the system management information file is input is not required to be registered by the user, improving operability and processing efficiency. 6) Further, in the billing error prevention method according to the present invention, since the record structure is not changed as compared with the conventional method, modification of the affected program group can be realized relatively easily. Etc. are obtained.
