CMS Pub. 100-04, ch. 30, § 140.6.2
Initial Physician Notices
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.
Include in the notice to the physician the following:
• The patient’s name and Medicare beneficiary identifier;
• A description of the service by procedure code, date and place of service, and
amount of the charge;
• The same denial notice included on the beneficiary’s MSN; and
• Depending on whether the beneficiary submitted a copy of an acceptable ABN
with his/her claim, include in the notice to the physician one of the following:
Notice 1 - Advance Beneficiary Notice Received Prior to Initial Determination
(The service identified above has been denied because/although payment
has been made to the patient for a less extensive service,) the information
furnished did not substantiate the need for the (more extensive) service.
Since you informed the beneficiary in writing prior to furnishing the
service that Medicare was likely to deny payment for the (more extensive)
service and the beneficiary signed a statement agreeing to pay, the
beneficiary is liable for (this/the more extensive) service.
Or
Notice 2 - Advance Beneficiary Notice Not Submitted
(The service identified above has been denied because/Although payment
has been made to the patient for a less extensive service,) the information
furnished did not substantiate the need for the (more extensive) service).
If you have collected (any amount from the patient/any amount that
exceeds your maximum allowable actual charge (MAAC) for the less
extensive service), the law requires you to refund that amount to the
patient within 30 days of receiving this notice. The law permits exceptions
to this refund requirement in two cases:
• If you did not know, and could not have reasonably been
expected to know, that Medicare would not pay for this
service; or
• If you notified the beneficiary in writing before providing
the service that you believed that Medicare was likely to
deny the service, and the beneficiary signed a statement
agreeing to pay for the service.
If you come within either exception, or if you believe the contractor was
wrong in its determination that Medicare does not pay for this service, you
should request an appeal of this determination by the contractor within 30
days of receiving this notice. Your request for appeal should include any
additional information necessary to support your position.
If you request an appeal within this 30 day period, you may delay
refunding the amount to the beneficiary until you receive the results of the
appeal. If the appeal determination is favorable to you, you do not have to
make any refund. If, however, the appeal is unfavorable, the law specifies
that you must make the refund within 15 days of receiving the unfavorable
appeal decision.
The law also permits you to request an appeal of the determination at any
time within six months of receiving this notice. An appeal requested after
the 30 day period does not permit you to delay making the refund.
Regardless of when an appeal is requested, the patient will be notified that
you have requested one, and will receive a copy of the determination.
The patient has received a separate notice of this denial decision. The
notice advises that he or she may be entitled to a refund of any amounts
paid, if you should have known that Medicare would not pay and did not
tell him or her. It also instructs the patient to contact your office if he or
she does not hear anything about a refund within 30 days.
The requirements for refund are in §1842(1) of the Social Security Act.
Section 1842(1) specifies that physicians who knowingly and willfully fail
to make appropriate refunds may be subject to civil money penalties
and/or exclusion from the Medicare program.
If you have any questions about this notice, please contact (Contractor
contact, telephone number).
The contractor will ensure that the telephone number puts the physician in touch with a
knowledgeable professional who can discuss the basis for the denial or reduction in
payment.
NOTE: These procedures do not apply to claims the contractor automatically denies
under the A/B link procedures. In those cases, the QIO is responsible for notifying the
beneficiary and physician of the refund requirements of §1842(1) and making the refund
determination where appropriate.
