ACA Section 6401—Ordering, Referring, and Prescribing Provider Requirements

Section 6401(b) of the Affordable Care Act (ACA) includes requirements related to Ordering, Referring, and Prescribing (ORP) providers.


If MassHealth requires a service to be ordered, referred, or prescribed, then ACA Section 6401(b) requires that the

  • Billing provider include the ORP provider’s individual National Provider Identifier (NPI) on the claim, AND the 
  • ORP provider be enrolled with MassHealth as a fully participating provider or as a nonbilling provider.

Note that there are other circumstances in which a nonbilling provider’s NPI may also be required on claims in order to comply with HIPAA version 5010 billing requirements.

To fulfill these requirements, MassHealth began enrolling qualified ORP nonbilling providers in June 2015.

When the ACA ORP requirements are fully implemented, MassHealth will deny claims for certain health care services requiring an order, referral, or prescription from a physician or other health care professional unless the ordering, prescribing, or referring provider’s individual NPI is included on the claim and that provider is actively enrolled with MassHealth, at least as a nonbilling provider. See below for more information on the affected claims.

Provider Types Authorized to Order, Refer, or Prescribe

The following types of providers are the only provider types that may be listed on a claim as the ORP provider and are referred to as authorized ORP providers. Interns, residents, and other trainees in the provider types listed below who are authorized to order, refer, or prescribe services are also considered ORP providers

Claims for the services listed above that are ordered, referred, or prescribed by a clinician who is not a provider type listed above must include the NPI of the clinician’s supervising physician (or other authorized ORP provider) on the claim. In that situation, the authorized ORP provider must also be enrolled in MassHealth as a fully participating provider or as a nonbilling provider in order for the billing provider’s claim to be payable. Note that pharmacy claims must include the individual NPI of the actual prescribing provider.

Massachusetts state law requires that the types of providers listed above apply for enrollment in MassHealth at least as a nonbilling provider in order to obtain and maintain state licensure.
