Medicare Denial for Secondary Insurers
Medicare may allow payment for services or items when those services or items are a covered benefit and provided by a person or entity enrolled with Medicare. For a general description of services payable by Medicare, please access the Centers for Medicare & Medicaid Services (CMS) Internet-Only Manual (IOM), Medicare General Information, Eligibility, and Entitlement Manual, Chapter 1, Section 10.3.
Providers should submit a claim for non-billable services directly to the patient's other insurance plan, not to Medicare. If the other insurance plan requires documentation of non-coverage, providers can access the references in this article and use a copy of this document with their claim.
Providers of services may not be able to enroll with Medicare as defined in the CMS IOM 100-08, Program Integrity Manual, Chapter 10, Section 6.2.1 and in the CMS IOM 100-04, Claims Processing, Chapter 12, Section 10. Those providers unable to enroll in Medicare based on their specialty and credentialing are also not able to submit claims to Medicare.
