(Rev. 13183; Issued: 04-24-25; Effective: 05-27-25; Implementation: 05-27-25)
The contractor should use or adapt the following paragraphs in explaining how the overpayment
occurred.
A. Inpatient Hospital Deductible or Coinsurance Not Properly Assessed – Part A
1. General – Part A
“Medicare pays all costs of covered services furnished during the first 60 days of hospitalization except
for the first $_____ (the inpatient deductible). For the 61st through the 90th days Medicare pays all
costs except for a coinsurance of $_____ per day. After 90 days of benefits have been used, an
additional 60 lifetime reserve days are available. There is $_____ per day coinsurance for each lifetime
reserve day used.
2. Deductible Overpayment
“Our records show that the claim for the inpatient services you received at (provider's name) was
improperly processed. Benefits were mistakenly paid for ____ days in full. However, since these were
the first inpatient hospital services furnished in this benefit period you are responsible for the deductible
and the $_____ inpatient hospital deductible should have been subtracted from the reimbursement paid
(provider's name) on your behalf. Thus (provider's name) was overpaid by $______.”
3. Coinsurance Overpayment
“Our records show that the claim for the inpatient services you received at (provider's name and
address) was improperly processed. Benefits were mistakenly paid for ____ full days (less the $____
deductible). However, since you had previously been hospitalized for ____ days at (name of provider
where previously hospitalized) during that benefit period, your claim should have been processed as ___
full days and ____ coinsurance days (and/or lifetime reserve days). Therefore (provider's name) has
been overpaid on your behalf for _____ coinsurance days at $_____ per day and/or lifetime reserve days
at $______ per day) (less $_____ for the inpatient hospital deductible which was improperly applied to
your claim). The total overpayment is $__________.”
B. Deductible Not Properly Assessed -Part B
“Under Part B of Medicare, no reimbursement may be made for the first $100 of approved charges
incurred by a beneficiary in each calendar year.” (If pertinent, add: “This is true even if you were
covered under Medicare for only part of the year.”) In these cases, explain the computation of the
overpayment.
C. Payment Made Under Workers’ Compensation Law
We paid $_____________ in benefits for services furnished you by (provider's, physician’s or supplier’s
name and location) on (dates). However, these payments were in error since these services were
covered under the (State) workers' compensation law and Medicare may not pay for services that are
covered under workers' compensation. Since (provider's, physician’s, supplier’s name) was not at fault
in causing this overpayment, you are required to refund the $_______________ Medicare paid on your
behalf. You may wish to submit the bill for these services to your employer or his workers'
compensation carrier for payment under the State workers' compensation provisions.”
D. Beneficiary Not Entitled to Medicare Benefits
"The Social Security Administration's records show that you were not entitled to (specify Part A
hospital insurance and/or Part B medical insurance) benefits when these services (item(s)) were
furnished. Your Medicare Handbook explains the difference between Part A (hospital) and Part B
(medical) insurance. The decision that you were not entitled to these benefits was made by the Social
Security Administration, and not by (contractor name). Therefore, if you disagree with this decision, or
if you have any questions about your entitlement to Medicare benefits, contact your Social Security
office. If you go to the Social Security office, take this letter with you.”
