How to Get a Medicare Provider Number


A Medicare provider number is known as a "national provider identifier," a ten-digit identification number for covered health care providers. The Centers for Medicare and Medicaid Services state that covered health care providers, health care plans and health care clearinghouses are required to have national provider identifiers for administrative and financial transactions under the Health Insurance Portability and Accountability Act (HIPAA). In order to obtain a national provider identifier, you will have to apply. You can download an application and mail it in or fill out the application and apply online.
