DME MAC Jurisdictions and Map

Each Durable Medical Equipment Administrative Contractor (DME MAC) is responsible for processing claims for specific states and territories. Claims must be submitted to the DME MAC that serves the state or territory where the Medicare beneficiary permanently resides.

For example: A supplier is located in California. The supplier provides Medicare-covered items to a Medicare beneficiary who calls Minnesota home for eight months of the year, but who spends about four months in California. The supplier is to submit the claim in to Jurisdiction B where the Medicare beneficiary lives most of the year and not to Jurisdiction D where the supplier is located or where the beneficiary is temporarily living.

Below is a list of each DME MAC and the states and territories they service.

Jurisdiction A is serviced by Noridian Healthcare Solutions and includes Connecticut, Delaware, District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island and Vermont.
