How Do I File Part B Claims to Medicare?
- File Electronically: Most providers submit electronic ANSI 837P claims
- Before filing claims electronically to Medicare, you must have an EDI enrollment packet on file with Palmetto GBA. See our Electronic Data Interchange (EDI) resources for more information on enrolling for electronic claim submissions.

- Palmetto GBA Interactive CMS-1500 Claim Form Instructions — This resource can also be helpful to providers who submit electronic claims. The help files for each CMS-1500 claim form field include the corresponding ANSI ASC 837P v5010 Loop, Segment, and Element, when applicable.
- File via Paper: Some providers that meet exceptions to mandatory electronic billing are allowed to submit CMS-1500 paper claim forms.
- The Administrative Simplification Compliance Act (ASCA) requires that Medicare claims be sent electronically unless a provider qualifies for an exception waiver. To see if you qualify for an exception, please reference page six of the Medicare Learning Network (MLN) Booklet Medicare Billing Form CMS-1500 and the 837 Professional.

The Advanced Communication Engine (ACE) Is Really SMART!
If you submit claims via the Electronic Data Interchange (EDI) option, our ACE tool will return pre-adjudicated Part B claims information through a claim acknowledgement transaction report, called a Medicare 277CA report. Submitters will receive the Medicare 277CA report with ACE smart edits if a claim is identified as containing a potential claim submission error that requires the submitters attention.
Smart Edits generate rejection alerts that provide submitters with granular messaging or educational awareness related to billing issues identified with their claim submission. The ACE tool affords you the opportunity to correct your billing issues prior to the claim being adjudicated in the claims processing system, allowing for more efficient and accurate claims processing.
