What Is CMS-1500 form?
The CMS-1500 is the standard paper claim form used by non-institutional providers (physicians, NPPs, suppliers) to bill Medicare and most commercial payers; its electronic equivalent is the 837P (Professional) HIPAA EDI transaction.
- Knowledge of CMS-1500 box numbers remains relevant because EHR/PM systems often label data fields by box number (Box 19 = additional claim information, Box 24G = days/units, Box 32 = service facility location).
- Mismapped data between EHR/PM and the 837P transaction is a common source of front-end rejections.
CMS-1500 form
Also known as: 1500 Claim Form; Health Insurance Claim Form; HCFA-1500 (former name)
The CMS-1500 is the standard paper claim form used by non-institutional providers (physicians, NPPs, suppliers) to bill Medicare and most commercial payers; its electronic equivalent is the 837P (Professional) HIPAA EDI transaction.
Definition
Maintained by the National Uniform Claim Committee (NUCC), the current version is the 02/12 form. It contains 33 numbered fields covering patient demographics, insurance information, diagnosis codes (Box 21, up to 12 ICD-10-CM codes), service lines (Box 24, up to six lines per claim), referring/ordering provider, and rendering/billing provider information (Boxes 31 and 33). The 837P electronic transaction uses ASC X12N standards and carries the same information in EDI format. CMS, all state Medicaid programs, and virtually all commercial payers accept CMS-1500/837P from physicians, NPPs, ambulance providers, DME suppliers, and laboratories.
Example
A primary care visit with CPT 99213, diagnosis E11.9 (Type 2 diabetes), submitted to BlueCross BlueShield uses the CMS-1500/837P. The same visit billed by a hospital outpatient department for the facility component would use the UB-04/837I instead.
Common Misconceptions
The CMS-1500 is mostly obsolete in paper form — over 99% of professional claims are submitted electronically as 837P. The paper form remains in use for limited circumstances (small-volume submitters under the Administrative Simplification Compliance Act exemption, certain Medicaid programs, and corrected paper claims).
Practical Application
Knowledge of CMS-1500 box numbers remains relevant because EHR/PM systems often label data fields by box number (Box 19 = additional claim information, Box 24G = days/units, Box 32 = service facility location). Mismapped data between EHR/PM and the 837P transaction is a common source of front-end rejections.
