CMS
change request (CR) 6417 expanded the scope of editing of electronic and paper claims to meet the requirements, established by the Social Security Act, for providers who order or refer items or services for Medicare beneficiaries.
• The ordering/referring providers must be uniquely identified in all Part B claims initiated by orders or referrals.
• The ordering/referring providers must have an NPI.
• The ordering/referring provider must be enrolled in Medicare and have a current enrollment record in the PECOS.
• The ordering/referring provider must be classified as a provider who is eligible to order or refer:
• Doctor of medicine or osteopathy
• Dental medicine
• Dental surgery
• Podiatric medicine
• Optometry
• Physician’s assistant
• Certified clinical nurse specialist
• Nurse practitioner
• Clinical psychologist
• Certified nurse midwife
• Clinical social workers
• Marriage and family therapist
• Mental health counselor
The purpose of the claim editing expansion is to verify that the ordering/referring provider identified on the claim meets the criteria. These requirements impact those Medicare claims that require an ordering/referring provider to be listed on the claim, which included some of the following types of claims:
• Claims billed by laboratories (e.g., diagnostic tests)
• Claims billed by imaging centers (e.g., Magnetic resonance imaging (MRI) tests, X-rays)
• Claims billed by suppliers of durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS)
• Claims billed by Part A home health agencies
If you receive the remittance advice remark code (RARC) N264: Missing/incomplete/invalid ordering provider name, the name submitted on the claim does not match the exact name included in the PECOS or in First Coast’s internal provider file.
To avoid this error -- N264: Missing/incomplete/invalid ordering provider name -- the billing provider should:
• Make sure that the names in the claim are submitted in the appropriate fields on the claim form.
• Do not include “MD,” “DO,” “Dr.,” or “PhD” in the name field.
• If the name is a hyphenated last name, it must be submitted exactly as it is in PECOS or in First Coast’s internal provider file on the claims system.
• Do not use middle names or initials.
• When submitting paper claims, use the following format for names in “block 17”: “First name, last name.”
If you receive the RARC N265: Missing/incomplete/invalid ordering provider primary identifier, the ordering/referring provider‘s NPI is not found in PECOS or in First Coast’s internal crosswalk file.
To avoid this error -- N265: Missing/incomplete/invalid ordering provider primary identifier -- the billing provider should:
• Make sure that the ordering/referring provider’s NPI included in the claim is the NPI of an individual and not of an organization
• Ensure the ordering/referring provider has verified his or her enrollment in Internet-based PECOS
• Ensure that the ordering/referring provider is classified as the type of specialty eligible to order/refer beneficiary services
Note: Billing providers can verify the eligibility of an ordering/referring provider by visiting the
Ordering Referring Report page (located on the CMS website) and downloading the current Medicare Ordering and Referring File.
