Revocation Format
40.2.1 - Revocation Format
(Rev. 257, Issued: 03-01-19, Effective: 04- 01-19 Implementation: 04- 01-19)
The term Medicare beneficiary identifier (Mbi) is a general term describing a
beneficiary's Medicare identification number. For purposes of this manual, Medicare
beneficiary identifier references both the Health Insurance Claim Number (HICN) and
the Medicare Beneficiary Identifier (MBI) during the new Medicare card transition
period and after for certain business areas that will continue to use the HICN as part of
their processes.
The revocation of an election not to use reserve days should specify the name of the
hospital, the admission date of the stay to which it applies and, if appropriate, the
effective date of revocation. The following model language is suggested:
Revocation of Election Not To Use Lifetime Reserve Days
I wish to revoke the election previously made by me or on my behalf not to use
lifetime reserve days to pay for the inpatient hospital services furnished me by
(name of hospital) during my stay there beginning (admission date). (If
appropriate add: I wish to revoke my election not to use lifetime reserve days for
the period from _____to_____.) I understand that my lifetime reserve days will
be used for these services (to the extent that I have such days available) but that I
will still be responsible to pay the Medicare coinsurance amounts and any charges
for services not covered under the Medicare program.
