Medicare Financial Management Manual (Pub. 100-06), Ch. 3 § 190
Collection of Fee-for-Service Payments Made During Periods of Medicare
190 – Collection of Fee-for-Service Payments Made During Periods of Medicare
Advantage (MA) Enrollment
(Rev. 315, Issued: 05-17-19, Effective: 06-18- 19, Implementation: 06-18-19)
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.
Effective October 1, 2003, Common Working File (CWF) implemented the informational unsolicited
response edit based on the same coding files made available for the reject edits in the risk-based MA
Enrollment coding files described in the CWF System Documentation at http://cms.csc.com/cwf/.
Upon receipt of notification that a beneficiary has previously enrolled in a MA Plan and the enrollment
is posted to the CWF, the CWF will search claims history to determine whether any fee-for-service
claims were erroneously approved for payment during a period of retroactive MA enrollment. The
CWF compares the period between the MA enrollment start date and the date of service of the claims in
history. Services that fall within the responsibility of the MA Organizations are identified.
The CWF generates an Informational Unsolicited Response (IUR) with trailers 05 & 24 containing the
identifying information regarding the claim subject to the risk based MA payment rules. The IUR has all
necessary information to identify the claim including the Internal Control Number or the Document
Control Number, and the Medicare beneficiary identifier. The CWF electronically transmits the IUR to
the contractor that originally processed the claim. The IUR is included in the existing CWF response
file. The IURs in that file for claims to be adjusted are identified with a unique transaction identifier.
The previously submitted claim is not canceled and will remain on the CWF paid claims history file,
pending subsequent adjustment.
Upon receipt of the IUR the Shared System software reads the trailer for each claim and either a manual
or automated adjustment is performed. The contractor must initiate overpayment recovery procedures
to retract the original Part A and Part B payment and must generate an adjustment to update or cancel
the claim to update CWF and contractor history.
Carriers
When CWF receives an adjustment for the fee-for-service claim on history, the deductible is updated on
the beneficiary’s file, and the corrected deductible information is returned to the carrier in trailer 11.
Carriers are to recover any monies due back to Medicare resulting from these denials, by following the
standard or (customary) recovery process. Carriers are also responsible for providing the M/A plan
number to the providers in their correspondence.
In the event that a denial is reversed upon appeal, for carrier claims, the Group Health Organization
(GHO) override code of ‘1’ must be used to allow payment.
Fiscal Intermediaries (FIs)
When CWF receives an adjustment for the fee-for-service claim on history, the deductible is updated on
the beneficiary’s file, and the corrected deductible information is returned to the intermediary in trailer
11. To recover any monies due back to Medicare resulting from these denials, claims are to be adjusted
and overpayments are to be recovered through the customary recovery process.
In the event that a denial is reversed upon appeal, a 1 byte override code field is created at the header
level for FI claims. The FIs should use override code “1” in this field for adjustments to all inpatient
claims, including home health. For an Outpatient Denial with a 'N' No Pay Code, use a value of '2' in
the HMO override field. The purpose of using “1” or “2” is to by-pass the CWF edit, which allows no
changes to the amount initially paid for claims.
Messages To Be Used With Denials Based On Unsolicited Response
The following messages should be used when the carrier receives a reject code from CWF indicating
that the services were rendered during a period when the beneficiary was enrolled in a MA, and billing
should have been submitted to the Managed Care Plan for payment.
Remittance Advice
At the claim level, report adjustment reason code 24 - Payment for Charges Adjusted. Charges are
covered under a capitation agreement/managed care plan.
Information to be made available to providers via letter (or an alternate method).
Language for Carriers to Use in Letter to Provider
Carriers
This beneficiary was enrolled in [Plan Alpha Numeric ID]; a risked based managed care organization,
for the date of service of this claim. You must contact the Managed Care organization for payment for
these services. A list that provides the MCO name and address associated with the MCO number is
available on the CMS Internet at
http://www.cms.hhs.gov/HealthPlansGenInfo/claimsprocessing20060120.asp#TopOfPage.
Fiscal Intermediaries
The plan number is not required on intermediary communications. Those providers are to determine
which plan to contact through an eligibility inquiry or by contacting the beneficiary directly.
