CMS Pub. 100-04, ch. 1, § 70.7.3
Retroactive Medicare Entitlement Involving State Medicaid
Agencies
(Rev. 2477, Issued: 05-25-12, Effective: 08-27-12 Implementation: 08-27-12)
The time for filing a claim will be extended if CMS or one of its contractors determines
that failure to meet the filing deadline is caused by all of the following conditions:
(a) At the time the service was furnished the beneficiary was not entitled to Medicare.
(b) The beneficiary subsequently received notification of Medicare entitlement
effective retroactively to or before the date of the furnished service.
(c) A State Medicaid Agency recovered the Medicaid payment for the furnished
service from a provider or supplier 6 months or more after the date of the
furnished service.
In these situations, at the time services were furnished the beneficiary was entitled to
Medicaid but not to Medicare. After the date of the furnished services, the beneficiary is
then notified that he or she is entitled to Medicare. Finally, sometime after the date of the
furnished service, the State Medicaid Agency recoups the money it paid the provider or
supplier. If the State Medicaid Agency recoups the money it paid the provider or supplier
6 months or more after the date the service was furnished, the provider or supplier may
be given an extension to have those claims filed to Medicare.
In order to qualify for this exception, the provider or supplier will need to provide the
claims processing contractor with the following information:
• documentation verifying the date that the State Medicaid Agency recouped money
from the provider/supplier;
• documentation verifying that the beneficiary was retroactively entitled to
Medicare to or before the date of the furnished service (e.g., an official SSA letter
to the beneficiary, or if an official SSA letter is not available, the contractor shall
check the CWF database and may interpret the CWF date of accretion and the
CWF Medicare entitlement date for a beneficiary in order to verify a beneficiary’s
retroactive entitlement; see the example in section 70.7.2 above concerning the
CWF for additional details regarding this contractor verification process); and,
• documentation verifying the service/s furnished to the beneficiary and the date of
the furnished service/s.
If the contractor determines that all of the conditions described above for meeting this
exception are met, the contractor will notify the provider or supplier in writing that a
filing extension will be allowed from the end of the 6th calendar month from the month in
which the State Medicaid Agency recovered its money.
