The Affordable Care Act, Section 6405, requires that physicians who order items or services must be Medicare enrolled providers or Eligible Professionals. The ordering/referring rule was implemented in 2 phases.

Phase 1 began October 5, 2009 to alert the billing provider that the ordering/referring provider was invalid on claims. The message was transmitted with EOMB’s to the billing provider office.

Phase 2 is effective May 1, 2013. Medicare will deny claims for Part B, DME and Part A HHA that fail the ordering/referring edits. The edits will compare the first letter of the first name and the first four letters of the last name of the ordering/referring provider. The comparison is made to the ordering referring file which can be found at n http://www.cms.gov/Medicare/Provider-Enrollment-and-Certification/MedicareProviderSupEnroll/MedicareOrderingandReferring.html

Only physicians and certain types of non-physician practitioners are eligible to order or refer items or services for Medicare beneficiaries. They are as follows:

  • Physicians (doctor of medicine or osteopathy, doctor of dental medicine, doctor of dental surgery, doctor of podiatric medicine, doctor of optometry, optometrists may only order and refer DMEPOS products/services and laboratory and X-Ray services payable under Medicare Part B.)
  • Physician Assistants,
  • Clinical Nurse Specialists,
  • Nurse Practitioners,
  • Clinical Psychologists,
  • Interns, Residents, and Fellows,
  • Certified Nurse Midwives, and
  • Clinical Social Workers.

CMS emphasizes that generally Medicare will only reimburse for specific items or services when those items or services are ordered or referred by providers or suppliers authorized by Medicare statute and regulation to do so. Claims that a billing provider or supplier submits in which the ordering/referring provider or supplier is not authorized by statute and regulation will be denied as a non-covered service. The denial will be based on the fact that neither statute nor regulation allows coverage of certain services when ordered or referred by the identified supplier or provider specialty. CMS would like to highlight the following limitations:

  • Chiropractors are not eligible to order or refer supplies or services for Medicare beneficiaries. All services ordered or referred by a chiropractor will be denied.
  • Home Health Agency (HHA) services may only be ordered or referred by a Doctor of Medicine (M.D.), Doctor of Osteopathy (D.O.), or Doctor of Podiatric Medicine (DPM). Claims for HHA services ordered by any other practitioner specialty will be denied.
  • Optometrists may only order and refer DMEPOS products/services, and laboratory and X-Ray services payable under Medicare Part B.
