Ordering & Certifying

Ordering & Certifying

Ordering & Certifying

Ordering providers can order non-physician services for patients. Referring providers can request items or services which Medicare may reimburse on behalf of Medicare beneficiaries.

To qualify as an ordering and certifying provider, you must:

  • Have an individual National Provider Identifier (NPI)i
  • Be enrolled in Medicare in either an “approved” or an “opt-out” status
  • Be of an eligible specialty type

If you’re currently enrolled as a Medicare Part B provider, you can already order and certify. You don't need to re-enroll in Medicare.

Access the Ordering & Certifying Files

The Ordering & Certifying Files contain a list all providers who are currently eligble to order and certify. These files are only available on the CMS Data website.
