Common Reasons for Denial

  • Item(s) billed did not have a valid ordering physician National Provider Identifier (NPI) registered in Medicare Provider Enrollment, Chain and Ownership System (PECOS)

Next Step

  • Resubmit claim with a valid ordering physician NPI registered in PECOS

How to Avoid Future Denials

  • Verify that ordering physician NPI is on list of physicians and other non-physician practitioners enrolled in PECOS. Even if a provider has an individual NPI, it does not mean that his/her enrollment record is in PECOS and/or is active. Verification of enrollment in PECOS can be done in below ways.
    • CMS: Check CMS ordering/referring provider downloadable report  which contains NPI, first name, and last name of providers enrolled in PECOS
    • Noridian Interactive Voice Response (IVR): Call Noridian IVR and select Option 6 to enter NPI and name of referring provider. IVR will respond if individual is or is not enrolled in PECOS
  • Be sure name and NPI entered for ordering provider belongs to a physician or non-physician practitioner. A group NPI cannot be used as ordering NPI on a Medicare claim. In addition, be sure qualifier in electronic claim (2310A NM102 loop) is a 1 (person). Organizations (qualifier 2) cannot order and refer
