    • Electronic claim: Be sure first and last names are submitted in correct field. Do not reverse order
  • Report first and last name of ordering physician exactly as listed on CMS Provider Enrollment, Chain and Ownership System (PECOS) files. Can be found in below sources.
    • 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
