What Are Revenue Codes?
Revenue codes are standardized four-digit codes used on the UB-04 (CMS-1450) claim form to identify the department, accommodation, or service category that provided care to a patient. They are used for institutional (facility) billing, while professional claims submitted on the CMS-1500 form do not use revenue codes.
Goals of Revenue Codes
Revenue codes help healthcare facilities accurately identify the department or service category responsible for patient care. They support proper claim processing, reimbursement, and compliance with payer requirements.
Identify the Service Department
Specify the hospital department or cost center that provided the service.
Support Institutional Billing
Provide the information required to submit accurate UB-04 facility claims.
Improve Claim Accuracy
Ensure facility charges are reported correctly to reduce billing errors.
Prevent Claim Denials
Use the appropriate revenue code to avoid claim rejections and reimbursement delays.
Support Accurate Reimbursement
Help insurance companies correctly process and reimburse institutional claims.
How Revenue Codes Work
Revenue codes are assigned by healthcare facilities when institutional services are provided to a patient. Each revenue code identifies the hospital department or service category responsible for the charge. The facility billing team enters the revenue code on the UB-04 (CMS-1450) claim form, along with the appropriate CPT®/HCPCS procedure codes (when required), diagnosis codes, and charge amounts. The insurance company reviews the claim and processes reimbursement based on the reported services and the patient’s benefits.

What is a revenue code?
A revenue code is a standardized four-digit numeric code used on the UB-04 (CMS-1450) claim form to identify the hospital department, accommodation, or service category responsible for a facility charge.
Where are revenue codes used?
Revenue codes are used only on institutional (UB-04/CMS-1450) claims submitted by hospitals, skilled nursing facilities, home health agencies, ambulatory surgery centers, rehabilitation facilities, and other institutional healthcare providers.
Are revenue codes the same as CPT® codes?
No. Revenue codes identify where a service was provided within a healthcare facility, while CPT®/HCPCS codes describe what medical service or procedure was performed.
Are revenue codes required on professional claims?
No. Professional claims submitted on the CMS-1500 claim form do not use revenue codes. Revenue codes are specific to institutional billing on the UB-04 claim form.
Can incorrect revenue codes cause claim denials?
Yes. Incorrect, missing, or mismatched revenue codes can result in claim rejections, payment delays, underpayments, or denials because the insurance company may be unable to determine the correct facility service category.
