The Notice of Medicare Non-Coverage (NOMNC) is a formal notice sent to Medicare beneficiaries to inform them of the termination of Medicare coverage for specific healthcare services or items. This notice is typically issued by skilled nursing facilities, home health agencies, or other providers when Medicare coverage for services is ending or being reduced. The NOMNC provides beneficiaries with information about their appeal rights and explains how to request a review if they disagree with the decision to terminate coverage. It serves as an important communication tool to ensure that beneficiaries are informed about changes in their Medicare coverage and have the opportunity to pursue further action if needed.
