What Is the CMS-1500 Claim Form?
The CMS-1500 claim form is the standard paper form used by healthcare professionals and suppliers to bill Medicare and many Medicaid State Agencies for services provided. It is designed for non-institutional providers and is essential for submitting claims when electronic filing is not feasible. The form is maintained by the National Uniform Claim Committee (NUCC).

Key Features of the CMS-1500 (Version 02/12)
- ICD Indicator: Specifies whether ICD-9 or ICD-10 codes are used, enhancing accuracy in diagnosis reporting.
- Diagnosis Codes: Allows up to 12 diagnosis codes, accommodating complex patient conditions.
- Standardized Format: Facilitates automated processing through Optical Character Recognition (OCR) systems.
It’s important to note that only the original red-ink CMS-1500 forms are acceptable for submission. Photocopies or black-and-white printouts are typically rejected due to OCR scanning requirements. Source
How to Complete the CMS-1500 Form Correctly
Accurate completion of the CMS-1500 form is crucial to ensure timely reimbursement. Here are some essential tips:
- Use Original Forms: Submit only the original red-ink CMS-1500 (02/12) forms.
- Typed or Computer-Printed: Handwritten forms can lead to processing errors; use a typewriter or computer.
- Font Specifications: Use all capital letters in Courier New or Times New Roman, size 10.
- Black Ink Only: Avoid using colored inks, as they can interfere with OCR scanning.
- Do Not Alter Forms: Avoid using correction fluid, tape, or highlighting on the form.
