Beginning 5/19/2025, there is a new mailing address for Medicare Part B claim submitters in Connecticut and New York (Upstate Counties and Queens).
In May 2025, providers submitting paper claims to Medicare will need to mail claims to the applicable P.O. Box listed below. The Post Office will return mail directed to closed P.O. Boxes.
Part B Paper Claim Submission Mailing Addresses beginning 5/19/2025:
| Claims (CMS-1500 forms) | All Jurisdiction K States: CT, MA, ME, NH, NY, RI, VT | National Government Services, Inc. P.O. Box 6178 Indianapolis, IN 46206-6178 |
NGS encourages providers to submit claims electronically. Electronic Data Interchange (EDI) is an electronic communication method that offers effective, accurate and reliable transactions. Claims submitted electronically process faster than paper submission. For example, HIPAA-compliant electronic claims are held in the payment floor for 14 days whereas paper claims are held in the payment floor for 29 days.
