Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a billing mistake prevention method in a medical fee billing process in a medical office system.

[0002] With the recent sophistication and complexity of medical contents,
There is a trend that medical remuneration claim processing is also complicated. For example, in addition to social insurance and national health insurance provided by the national medical management organization, there is a welfare measure system unique to the prefecture that is a local municipality. In each medical institution, the necessary contraindicated check contents are registered and referenced independently.

[0003] In this case, in the medical treatment fee processing in the medical office system, the contraindicated check contents determined by the national medical management organization and the contraindicated check contents uniquely registered in each medical institution are mixed. It is necessary to be able to selectively check necessary contraindications for each medical care action code.

In the contraindicated 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 medical practice code with the higher score. In the contraindicated check, it is necessary to determine which of the priorities should be calculated for each medical care action code.

[0005] In some cases, the contraindications check at the time of performing the medical treatment fee processing may be performed in batches on a monthly basis depending on the medical institution. Therefore, it is necessary that the contraindications check at the time of performing the medical treatment fee processing has a room to select whether to perform the medical treatment action in real time or on a monthly basis in batch processing.

[0006]

2. Description of the Related Art FIG. 6 is a diagram for explaining a conventional method of checking contraindications for medical practice. FIG. 6 (a) shows a data format of a medical practice master, and FIG. Indicates the format of the conventional system management information file,
FIG. 7 is a flowchart showing a conventional medical treatment fee requesting process.

First, in the medical office system, the contents of the medical treatment for each patient for one month are received (receipt statement).
In order to make a claim to an insurance institution, daily medical treatment contents are input to the medical office system.

[0008] Incorrect billing, such as an operator's incorrect input or insufficient input, causes a great deal of profit or loss to the medical institution. Conventionally, however, information of a medical practice code in the format of a medical practice master shown in FIG. Then, referring to the system management information file 1 in the format shown in FIG.
A contraindication check of medical treatment is performed, that is, a medical treatment code that is double charged when calculated at the same time is checked to prevent a billing mistake.

Next, each information of the medical treatment code for each patient stored in the medical treatment master file shown in FIG. 6A will be described.

Code: A key (KEY) item serving as record control information for managing the medical practice master itself.
It is represented by a five-digit number. Abbreviation: The accounting entry made for each patient is entered using this abbreviation code. Consultation area: An information item that defines in detail the position on the receipt paper where the medical treatment is counted. Medical practice name: The name of the medical practice is stored. Score: Stores the insurance score for each medical treatment set by the national medical management organization (Ministry of Health and Welfare). Warning number: This is information that allows a warning message to be displayed to prevent omission of billing when entering a medical practice. Other: In addition to the above information, there is information necessary for calculating the insurance score.

FIG. 6B shows a system management information file necessary for performing a medical practice and a contraindication check of the medical practice.

[0012] In order to check for billing errors and omissions commonly occurring in medical institutions throughout the country, there is a fixed billing error check inside the medical office system. This is the contraindicated check of the medical treatment and the medical treatment, which is a check of the medical treatment code which is double-billed at the time of receipt. Conventionally, the medical treatment code which cannot be calculated simultaneously in the same month is checked.

The system management information file 1 contains FIG.
The information shown in (b) is stored. That is, a key (KEY) part: stores a code of “medical practice master” (see FIG. 6A), which is a target of the contraindications check.

Codes (1) to (15): Store the codes of the "medical practice master" which cannot be calculated in the same month as the medical care code indicated by the key part (KEY).

The code of the system management information file
Since the medical treatment indicated by the code indicated by (1) to (15) includes the same medical treatment as the medical treatment indicated by the medical code indicated by the key (KEY) part, the medical treatment code ( If 1) to (15) have been entered, entering a new medical code indicated by the key (KEY) section will result in double billing and prevent input errors. I have.

FIG. 7 shows an outline of a medical reimbursement request process when an accounting card for creating the above-mentioned claim is generated. This process will be described with reference to the information on the medical treatment code for each patient in the medical treatment master shown in FIG. 6A and the system management information file 1 shown in FIG. 6B.

The accounting card file, which is data when creating the receipt, stores information on the medical treatment code in the format shown in FIG. 6A together with the input date for each patient. However, in the medical treatment fee request processing described below, the processing is performed on a monthly basis.

First, the operator inputs the information on the medical treatment code of a certain patient in the format of the medical treatment master shown in FIG. 6 (a). (Refer to processing step 100) It is searched whether or not the medical care action code (corresponding to the KEY part code 10 of the system management information file 1 in FIG. 6B) exists in the KEY part 10 of the system management information file 1. If the corresponding system management information file 1 does not exist, it is determined that it is not a medical treatment code to be accounted for, and nothing is performed, and the process returns to the processing step 100.If the corresponding system management information file 1 exists, , The accounting card file 2 described later is searched, and if the same medical practice code exists in the accounting card file 2 for that month, the corresponding medical practice code is set in the contraindicated check target code (1 ) To (15) 11 are checked to see if they are
If it does not exist in (1), it is registered in the accounting card file 2 as it is as a medical treatment that does not become a double request, but the contraindicated check target code (1) to (15) in the system management information file 1 11 is a medical practice code that requires a contraindicated check, and if the medical practice information code is registered in the accounting card file, it will be a double request, so "" medical practice code A " The message "Action code B" cannot be calculated in the same month "is displayed to prevent the operator from making a mistake in billing (see processing steps 101 to 104).

[0019]

In the conventional medical treatment fee processing, contraindications of medical practice codes within the same month can be checked, but contraindications cannot be checked within the same day. There was a problem that it was necessary to search all files 2 and it took time to search.

In the above-mentioned conventional medical fee billing process, a billing mistake can be checked only when the medical care action code of the KEY section 10 of the system management information file 1 is input. (1) to (15)
The contraindication check cannot be performed at the time of inputting the medical treatment code of No. 11, and in order to perform this contraindication check, the medical treatment code of the code (1) to (15) must be changed to KEY
There is a problem that double registration is required when an operator registers a record in the system management information file 1 as part 10.

In view of the above-mentioned conventional disadvantages, the present invention provides a medical office system and a billing error prevention method which can more accurately prevent a billing error in a medical office system in accordance with the operation mode of each medical institution. It is intended to provide.

[0022]

[Means for Solving the Problems] In a medical office system, simultaneous calculation is performed by referring to a system management information file when inputting a medical treatment code and generating an accounting card file required for issuing a receipt. When performing the contraindicated check by suppressing the input of the medical treatment code that cannot be performed,
Apart from the system management information file generated based on the contraindications check table, the code of the key information and the code of one piece of contraindication check target code stored in the generated system management information file are exchanged. A system management information file generated by inverting the type management flag of the code information of the contraindicated check target on which the operation is performed is generated for each stored code information of the contraindicated check target.

Further, the medical care action code to be input includes
A process identification flag is provided for discriminating whether to perform the contraindicated check in batch processing or real-time processing, and the contraindicated check is performed in the process specified by the process identification flag.

[0024]

According to the contraindication check method of the present invention, not only is a billing error check performed when the medical care action code of the KEY portion of the system management information file is input, but also a medical care action for which the code of the system management information file is subject to the contraindications check Even when the code is input, the user registers the above contraindicated check table so that a billing error check can be performed, and when the user generates a record of the system management information file of the contraindicated check condition, the user performs the reverse pattern one by one. In the medical office system, based on the contraindication check table generated by the user, a record of the system management information file in which the contraindicated check target code is set in the KEY part is generated so that registration is not required.

Further, a treatment identification flag is provided in the medical treatment code input in the format of the medical treatment master,
If the processing identification flag is "0", a contraindicated check is performed when the medical treatment accounting card file is created. However, if the processing identification flag is "1", a contraindicated check is performed when the medical accounting card file is created. Without performing the process, the accounting card file is constructed as it is, the accounting card file for the month that has been separately created is read out at the end of the month, and the above contraindications check is performed, so that the process requested by the user is performed. It becomes possible to respond flexibly to the form.

[0026]

FIG. 1 is a diagram illustrating the principle of the present invention. The present invention is achieved by a medical office system and a billing mistake prevention method configured as described below.

(1) In the medical office system, it is not possible to simultaneously calculate by referring to the system management information file 1 when entering the medical treatment code and generating the accounting card file 2 necessary for issuing a receipt. This is a method of suppressing the input of a medical treatment code, wherein a classification management flag is provided in the key (KEY) part 10 of the system management information file 1 for discriminating between the same month contraindicated check and the same day contraindicated check. It is configured to perform a contraindicated check corresponding to the value of the flag.

(2) Code information of the contraindications check of the system management information file 1 {codes (1) to (15) # 11
A type management flag is provided to distinguish whether calculation is performed preferentially with the code to be checked indicated by the key (KEY) part 10 of the system management information file 1 or with the contraindicated code of each code information 11 described above. Therefore, when performing the contraindications check in the above item 1, the code specified by the value of the type management flag is preferentially calculated.

(3) Key of system management information file (KE
Y) In section 10, a serial number management flag is provided for distinguishing whether the system management information file is a fixed check content of the medical office system or a new user's own check content. When updating,
It is configured to be selectively updated based on the serial number management flag.

(4) Based on the contraindications check table,
When the system management information file 1 is generated, when each code information 11 to be contraindicated is input, the code information 11 of the contraindicated check is used as a key (KYE) for performing the contraindicated check indicated by the type management flag. ) Generate system management information file 1a for Part 10.

(5) In the input medical care action code,
A processing identification flag for distinguishing whether to perform the contraindications check described in the above items 1 to 4 in batch processing or real time processing is provided, and the contraindications check is performed in the processing indicated by the processing identification flag. Constitute.

1 to 3 are explanatory diagrams of the principle of the present invention. FIG. 1 shows an example of the configuration of a system management information file.
FIG. 2 shows an example of registration of a contraindication check table by a user, and FIG. 3 shows an example of generation of a system management information file. In the claim mistake 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 for distinguishing between the same month contraindicated check and the same day contraindicated check. If the section management flag is "0", the same month contraindications check is performed, and if the section management flag is "1", the same day contraindications check is performed.

By performing a contraindication check using “medical practice code + α (classification management flag)”, a conventional “same month contraindication check” and a new “same day contraindication check” can be performed. Is performed, on the accounting card file 2, it is only necessary to search for the registered medical treatment code of the same date for the medical treatment code to be entered, and the effect of speeding up the search process is obtained. .

In this case, if the classification management flag is "0", a message "" Medical practice code A "cannot be calculated in the same month as" medical practice code B "" is displayed, and the classification management flag is "1". In the case of, a message is displayed indicating that "medical treatment code A" cannot be calculated on the same day as "medical treatment code B" .In other words, the same month and the same day can be distinguished by the value of the division management flag. .

2) The system management information file 1 according to the present invention has its contraindicated check codes (1) to (15) 11
It is distinguished whether to preferentially calculate the check target code indicated by the key (KEY) part 10 of the system management information file 1 or to preferentially calculate the contraindicated target code of each code information 11 above. Provide a type management flag,
When the type management flag is “0”, the code to be checked is calculated preferentially, and the code to be prioritized is displayed, for example, on the left side in the contraindicated check message. "Example of contraindicated check message when type management flag = 0" is ""
"Training fee" (check target code) cannot be calculated on the same day as "Nursing home nursing at home / guest fee" (contraindicated check target code) "and" Example of contraindicated check message when type management flag = 1 " `` Nursing home nursing fee
"Training fee" (contraindicated check target code) cannot be calculated on the same day as "Psychiatric home visit nursing and guidance fee" (check target code).

By providing such a function, as described above, the “medical practice code A” and the “medical practice code B” cannot be calculated on the same day, but if “calculated anyway”, the higher score is obtained. For the needs of medical institution managers (users), such as “I want”, the contraindications check message can be given the meaning of the priority calculation.

3) As described above, the content of the contraindications check is based on the fact that the treatment of the medical reimbursement request processing differs depending on the medical care action code and the like. The contraindication check table shown in Fig. 2 is separately provided by the user with the same record structure so that the user can register, refer to, and change, while retaining the contents of the contraindication check prescribed by the conventional national medical management organization (Ministry of Health and Welfare) Are generated at the same time, and as shown in FIG.
10, the system management information file 1 is updated by providing a serial number management flag for distinguishing whether the system management information file 1 is a fixed judgment check content in the medical office system or a new user's own check content. At this time, the information is selectively updated based on the serial number management flag.

When the serial number management flag is “0”, the check is a contraindicated judgment fixed to the medical office system, and when the serial number management flag is “1”, the check is a contraindicated judgment set by the user.

Then, the user can register and change only the contraindicated check table in which the serial number management flag is "1", and can infringe the fixed contraindicated check table a in the medical office system. Keep away.

By adopting such a configuration, when the national medical management organization (Ministry of Health and Welfare) has changed the medical system, the serial number management flag is set to "0" on the maker side of the medical office system. By updating the corresponding contraindicated check table a in a batch, the contraindicated check method can be updated without affecting the contraindicated check table created by the user.

4) In the method of checking contraindications of the present invention,
In addition to performing a billing error check when entering the medical practice code of the KEY part 10 of the system management information file 1, the codes (1) to (15) of the system management information file 1
Even when the medical action code subject to the 11 contraindications check is entered, the user must
When the above-mentioned contraindicated check table is registered and a record of the system management information file 1 of the contraindicated check condition is generated, in the medical office system, the user is not required to register a reverse pattern. Based on the generated contraindication check table, a record of the system management information file 1a in which the contraindication check target code is set in the KEY part 10 is generated.

At this time, the process shown in FIG. 3 is performed in order to keep the meaning of the type management flag in the message. That is, a) the user himself registers the contraindicated check condition using the “contraindicated check table”.

B) A record of "system management information file" 1 is generated according to the instruction of a).

C) To prevent the user from having to register the reverse pattern and generate the system information file 1,
A record of the “system management information file” 1a having the reverse pattern is generated inside the medical office system.

FIG. 3A shows an example of a contraindication check table registered by the user. In this example, the code to be checked is “08256” “Psychiatric on-site nursing care / guidance fee”. Based on the table, 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” is “0”, the priority when requesting a medical fee is determined by the check target code (08256)>
The contraindication check target code is (00101), and the reverse pattern generated by the medical office system is as shown in FIG.
In the case of a) above, the message of the contraindicated check result is a check target code (08256)>"Contraindicatedcheck" such as "" Clinical practice code "08256""cannot be calculated on the same day as" Clinical practice code "00101""" Object code (001
01). Here, the KEY part 10 of the system information management file 1 and the contraindicated check target code (1)
By simply reversing ~ (15) 11, a message such as "" Medical action code "00101""cannot be calculated on the same day as" Medical action code "08256""" is displayed, and contraindications are checked from the message. Object code (00101)>
Since the code becomes a check target code (08256), in the medical treatment fee processing of the present invention, the type management flag is changed from “0” to “1”, and the message when the medical care action code (00101) is input is also changed. , "" Medical practice code "08256""
Cannot be calculated on the same day as "medical practice code" 00101 "".

5) In the example described in the above 1) to 4), an example is described in which the operator performs a contraindicated check at the time of creating the accounting card file 2 by inputting the medical care action code. Depending on the (user), at the time of inputting the medical care action code, in particular, the input may be performed without performing the contraindicated check, and the contraindicated check processing may be performed in batch processing at the end of the month.

Therefore, in the medical treatment fee request processing of the present invention,
As shown in FIG. 3 (d), a treatment identification flag is provided in the medical treatment code input in the format of the medical treatment master, and when the treatment identification flag is “0”,
When the medical treatment accounting card file 2 is created, a contraindicated check is performed. When the processing identification flag is “1”, the accounting card is left as it is without performing a contraindicated check when the medical treatment accounting card file 2 is created. File 2 is constructed, and at the end of the month, the separately created accounting card file 2 for that month is read and the above contraindications check is performed, thereby flexibly responding to the processing form requested by the user. Will be able to

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 3 are explanatory diagrams of the principle of the present invention.

Information 11 is keyed (K
(YE) Means for generating the system management information file 1 to be the part 10, and processing identification for discriminating whether the above contraindicated check is performed in batch processing or real-time processing in the input medical care action code Means for providing a flag is a means necessary to carry out the present invention. Note that the same reference numerals indicate the same object throughout the drawings.

Hereinafter, referring to FIGS. 1 to 3, FIG.
Referring to FIG. 5, the medical treatment fee processing according to the present invention will be described.

First, the medical care action code of the medical care action master is input from the medical care accounting screen for generating the accounting card file 2. << Refer to the processing step 200 in FIG. 4 >> In the next processing step 200a, the processing identification flag of the present invention is checked, and if the processing identification flag is "0",
The present medical treatment fee requesting process is started. If the process identification flag is “1”, the medical treatment code is temporarily stored in the accounting card file 2 without performing the contraindicated check because of the batch process. In advance, at the end of the month, the accounting card file 2 is read, and the processing of the next processing steps 201 to 201 is performed by batch processing.

In the processing step 201, the system management information file
If the relevant medical action code does not exist in the KEY part 10 of the system management information file 1, the process returns to the processing step 200 without doing anything because it is not the medical action code to be accounted for. If the medical care action code exists in the KEY section 10, the following processing step 2
Move to 03. << Refer to processing steps 201 and 202 in FIG. 4 >> If the section management flag of the corresponding code in the system management information file 1 is "0", the code for the contraindicated check
Look at (1) to (15) 11 and for each of them, the same
2, if the classification management flag of the corresponding code in the system management information file 1 is “1”, the same medical care action code is included in the accounting card file 2 in the month and date. Check that it exists, and if it does not exist, it is not a code for contraindications check,
As it is, it is entered in the accounting card file 2, but if it exists, it refers to the type management flag of the corresponding contraindicated check target code (1) to (15) 11 in that system management information file 1, and If the type management flag is “0”, the code to be checked is calculated with priority, and “the code to be checked A cannot be calculated the same month (or the same day as the code B to be contraindicated)” Then, the process proceeds to the next processing step 205. If the type management flag is “1”, the contraindicated check target code is calculated preferentially. Code A ”and the same month (or
The system proceeds to the next processing step 205. The above processing is repeated for the contraindicated check target codes (1) to (15) 11 of the system management information file 1. {FIG. Refer to processing steps 203 and 204. In the next processing step 205, the relevant medical care action code is
Since a simultaneous calculation cannot be performed on the same month or on the same month, a predetermined message is displayed on the screen of the accounting card, the process returns to the first processing step 200, and the next medical treatment code is input.

Note that the serial management flag for distinguishing whether the system management information file 1 is a fixed check content of the medical office system or a new user's own check content is particularly conscious in the medical treatment fee processing. This is a management flag for the medical office system to perform management. Usually, the user only needs to read the contents of the system management information file 1 whose serial number management flag is “1”.
Can be registered and changed.

As described above, the present invention refers to the system management information file for generating the accounting card by inputting the medical treatment action code required for issuing a receipt in the medical office system, and This is a method of suppressing the input of a medical treatment code that cannot be calculated, wherein a key (KEY) portion of the system management information file is provided with a classification management flag for distinguishing between the same month contraindicated check and the same day contraindicated check. In addition, a type management flag is provided for each piece of code information of the contraindicated check in the system management information file to determine whether the code to be checked is calculated preferentially or the code to be contraindicated is calculated preferentially. Also, in the key (KEY) part of the system management information file, as the system management information file, a serial number management flag for distinguishing between fixed judgment check contents in the medical office system and new user's own check contents may be provided. There is a feature in the place.

[0055]

As described above in detail, according to the medical office system and the billing mistake prevention processing method of the present invention, 1) the billing mistake can be prevented according to the operation mode of each medical institution. . 2) According to the division management flag in the system management information file, contraindications can be checked for both the same month and the same day. Then, when the contraindications are checked on the same day, the search for the specified date can be completed for the accounting card file, so that the medical remuneration claim processing can be sped up. 3) With the type management flag in the system management information file, the calculation priority condition in the message text can be specified, and it is possible to flexibly respond to the user's request. 4) By the serial number management flag of the system management information file, it is possible to select whether the medical reimbursement request processing is fixed judgment in the medical office system or user-specific judgment for each medical care action code. Can respond flexibly to the requirements of Five)
This eliminates the need for the user to register the system management information file required for the contraindicated check when the code for the contraindicated check of the system management information file is input, thereby improving operability and processing efficiency. 6) In the billing mistake 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.
