130 CMR 450.204
Medical Necessity
The MassHealth agency does not pay a provider for services that are not medically necessary
and may impose sanctions on a provider for providing or prescribing a service or for admitting a
member to an inpatient facility where such service or admission is not medically necessary.
(A) A service is medically necessary if
(1) it is reasonably calculated to prevent, diagnose, prevent the worsening of, alleviate,
correct, or cure conditions in the member that endanger life, cause suffering or pain, cause
physical deformity or malfunction, threaten to cause or to aggravate a handicap, or result in
illness or infirmity; and
(2) there is no other medical service or site of service, comparable in effect, available, and
suitable for the member requesting the service, that is more conservative or less costly to the
MassHealth agency. Services that are less costly to the MassHealth agency include, but are
not limited to, health care reasonably known by the provider, or identified by the MassHealth
agency pursuant to a prior-authorization request, to be available to the member through
sources described in 130 CMR 450.317(C), 503.007: Potential Sources of Health Care, or
517.007: Utilization of Potential Benefits.
(B) Medically necessary services must be of a quality that meets professionally recognized
standards of health care, and must be substantiated by records including evidence of such medical
necessity and quality. A provider must make those records, including medical records, available
to the MassHealth agency upon request. (See 42 U.S.C. 1396a(a)(30) and 42 CFR 440.230 and
440.260.)
2. Administrative Regulations
(C) A provider's opinion or clinical determination that a service is not medically necessary does
not constitute an action by the MassHealth agency.
(D) Additional requirements about the medical necessity of MassHealth services are contained in
other MassHealth regulations and medical necessity and coverage guidelines.
(E) Any regulatory or contractual exclusion from payment of experimental or unproven services
refers to any service for which there is insufficient authoritative evidence that such service is
reasonably calculated to have the effect described in 130 CMR 450.204(A)(1).
