130 CMR 450.226
Provider Contract: Issuance of Provider ID/Service Location Numbers
(A) Upon execution of the provider contract, the MassHealth agency will issue a provider
ID/service location number or numbers to be used to identify the provider that is the subject of
the contract.
(B) For every case in which a provider is assigned two or more provider ID/service location
numbers, the provider must use each provider ID/service location number only in conjunction
with the facility or location to which the provider ID/service location number is assigned. The
MassHealth agency, however, maintains its right to commence proceedings in accordance with
the provisions of 130 CMR 450.235 through 450.248 against any or all of its provider ID/service
location numbers, regardless of the location or facility where the violation has been alleged to
have occurred or the overpayment received.
(C) The MassHealth agency may require providers to obtain separate national provider
identifiers (NPIs) for each service location and may deem it necessary to issue separate provider
ID/service location numbers for separate service locations. The MassHealth agency may specify
such requirements through provider bulletins, billing guidance, provider enrollment instructions,
or other subregulatory written issuance.
