Medicare Program Integrity Manual (Pub. 100-08), § 14.1
of the Act Determination- Limitation of Liability - (Rev. 3,
14.1 - Section 1879 of the Act Determination- Limitation of Liability - (Rev. 3,
11-22-00)
Section 1879 provides relief for a beneficiary who acted in good faith in accepting services
found to be not reasonable and necessary for the diagnosis or treatment of illness or injury or to
improve the functioning of a malformed body member, or to constitute custodial care. The
provision also applies to denials of home health services beginning July 1, 1987 and ending
September 30, 1989, where the beneficiary is not homebound or does not or did not need skilled
nursing care on an intermittent basis. The provision applies to all carrier determinations on all
assigned claims when claims are denied (prepay or postpay) under §1862(a)(1) of the
Act. Contractors must make an individualized determination for each claim that is denied as not
reasonable and necessary.
A §1879 determination regarding knowledge is part of the framework for determining whether
an actual or potential overpayment exists. If a contractor determines that program payment was
proper because neither the beneficiary nor the provider knew or should have known that the
service was not reasonable and necessary, no overpayment exists. However, if the contractor
determines that either the beneficiary or the provider knew or should have known that a service
was not medically reasonable and necessary, an overpayment exists. Contractors must consider
waiver of recovery of the overpayment under §1870 of the Act.
A. Documentation of §1879 of the Act Determination
The contractor must document the basis for the determination (i.e., rationale), including
appropriate references to contractor newsletters, prior denials, sponsored meetings attended by
the provider, etc., where applicable. Any correspondence going to the beneficiary/provider (i.e.,
demand letters) should include all §1879 determinations as to knowledge of noncoverage, both
favorable and unfavorable. Document the §1879 determination in the CMR summary report.
B. Section 1879 of the Act Determinations and Overpayments
An overpayment would be $0 (zero) for postpayment denials for assigned claims and claims
submitted to an intermediary from a participating provider because a determination was made
that neither the beneficiary nor the provider knew or should have known the services were not
covered. Program payment was appropriate. However, if the beneficiary is found to be liable
under §1879 of the Act, an overpayment to the beneficiary exists and the contractor must make
an §1870 determination.
