CMS-1500
The CMS-1500 is the standard paper claim form for professional services — the layout behind what most practices submit electronically as an 837P.
Updated
The CMS-1500 is the standard claim form used to bill professional services — the work of physicians, non-physician practitioners, and most outpatient providers. It is maintained by the National Uniform Claim Committee (NUCC), and its fields define what a professional claim has to report.
Most claims are not filed on paper. The CMS-1500 remains the reference layout for professional billing, but the same information is normally transmitted electronically as an 837P — the professional variant of the health care claim transaction adopted under HIPAA. Learning the form is still how many billers learn the claim, because the electronic transaction carries the same data in a different shape.
The form is versioned, and the version matters more than the name. NUCC publishes it as the 1500 Claim Form and the current one is the 02/12 version, in effect since April 1, 2014 — so a payer instruction or a template referring to an earlier revision is referring to a superseded layout.
In practice
Its counterpart is the UB-04, which bills institutional services. Which form a service belongs on is determined by who is billing and in what setting, not by preference — and billing a service on the wrong one is a structural error that a payer will refuse.
Commonly confused with
- UB-04: The UB-04 bills institutional services (hospitals, facilities); the CMS-1500 bills professional services. Different committees maintain them and they carry different data.
- 837P: The 837P is the electronic transaction carrying professional claim data; the CMS-1500 is the paper form for the same. The 837P is what is actually transmitted in nearly all cases.
