Unique 4 Digit Numbers
Medical coding and billing is a complex procedure. That’s where Revenue Codes come into play to help make the whole process smoother and universal.
In short, Revenue Codes are descriptions and dollar amounts charged for hospital services provided to a patient. The revenue code tells an insurance company whether the procedure was performed in the emergency room, operating room or another department.
3 Different Sets of Codes
Hospitals run on three sets of universal codes:
- ICD-9 – for diagnoses
- CPT – for procedures
- HCPCS – for medical goods and services.
These codes are located in various places on the UB-04 forms (bill form used by Hospitals and other providers), the purpose of Revenue Codes, however, is to group similar types of charges onto one line in the form.
If a revenue code is attached to a supply code, it identifies the equipment and whether the equipment was used in the hospital or taken home by a patient. This is important because many of the procedures done in the hospital may be done in different areas. For example, stitches may be given to a patient in the emergency room, or in a completely different area of the hospital like the maternity ward. Depending on where the procedure was done the price for the procedure can be drastically different. We therefore see the tremendous role that Revenue Codes have in the revenue cycle of a hospital.
A valid procedure code must be accompanied by a revenue code for it to be accepted by the insurance provider. There are 81 fields on the UB-04 and the Revenue Codes are located by field 42-49 (FL42-49). The Revenue Codes were developed for the Medicare system but were soon adopted as standard for hospitals. Every item in a hospital’s chargemaster (catalog of all services performed by that hospital) must have one revenue code attached to it.
From 3 to 4 Digits
Originally Revenue Codes were 3 digits, however, the need for additional codes required the addition of a new digit. Nowadays, the code is always 4 digits, the first digit is typically a zero and many insurance agencies will assume a zero for the first digit rather than require it to be listed. When the last digit of a Revenue Code is a zero this indicates that the service was unspecified and a more specific assignment could not be made. When the last digit is a nine this indicates that “other” services within the specified category were performed which do not have a specific code assigned to them. A claim form sent to an insurance provider without a Revenue Code will be rejected, and only Revenue Codes that are covered by the insurance provider will be paid.
The list of Revenue Codes is quite extensive. To demonstrate just how many codes there are, check out this list:
