Let's talk about the PECOS lookup

The Provider Enrollment, Chain and Ownership System (PECOS) is a database of physicians or non-physician practitioner who are enrolled with Medicare. It allows registered users to securely and electronically submit and manage Medicare enrollment information.

For example, A physician wants to prescribe an item for his patients like a knee brace, the supplier must list the National Provider Identifier (NPI) number on the claim file. This NPI number will link that physicians provider file inside the PECOS system.

In order for a DMEPOS item to qualify for coverage by Medicare, a physician or a practitioner who is PECOS eligible to order the item must write the prescription. That physician must meet these requirements:

  1. Physicians or practitioners have registered in PECOS.
  2. Have a specialty that is eligible to order DMEPOS items for Medicare beneficiaries.
