CMS Pub. 100-08, ch. 3, § 3.6.3
Beneficiary Notification
This section applies to MACs, CERT, RACs, and UPICs, as indicated.
A. General
If a claim is denied through prepayment or postpayment review, the MAC shall notify the
beneficiary consistent with the requirements in PIM chapter 3, §3.6.2.3. The MAC shall
include limitation of liability and appeals information. Notification can occur via
Medicare Summary Notice (MSN). The CERT, RACs, and UPICs are not required to
issue beneficiary notices for claims they deny. Instead, CERT, RACs, and UPICs shall
communicate sufficient information to the MAC to allow the MAC to develop an
appropriate beneficiary notice.
The MACs are required to give notice to Medicare beneficiaries when claims are denied
in part or in whole based on application of a LCD. All denials that result from LCDs shall
provide the MSN message 15.19 in addition to the current applicable message. Message
15.19 states (IOM Pub. 100-04, chapter 21):
“A local coverage determination (LCD) was used when we made
this decision. A LCD provides a guide to assist in determining
whether a particular item or service is covered by Medicare. A copy
of this policy is available from your local intermediary, carrier or
(Medicare Administrative Contractor) by calling the number in the
customer service information box on page one. You can compare the
facts in your case to the guidelines set out in the LCD to see whether
additional information from your physician would change our
decision.”
The MACs shall make these messages available in Spanish where appropriate. The 15.19
portion of the MSN message states:
Una Determinación de Cobertura Local (LCD, por sus siglas en
inglés) fue utilizada cuando se tomó esta decisión. La LCD es una
guía que ayuda a determinar si un artículo o servicio en particular
está cubierto por Medicare. Una copia de esta póliza está disponible
en su intermediario, local o en su empresa de seguros Medicare, o en
su Contratista Administrative de Medicare, al llamar al número que
aparece en la información de Servicios al Cliente en la página uno.
Usted puede comparar los datos de su caso con las reglas
establecidas en la LCD para ver si obteniendo información adicional
de su médico pudiera cambiar nuestra decisión.
The MACs shall use the above message in every instance of a prepayment denial where a
LCD was used in reviewing the claim. Use this message, and message 15.20 (now for
FISS MACs, and when 15.20 is fully implemented for contractors on the MCS/VMS
systems) on both full and partial denials, whether the denial was made following
automated, non-medical review, or medical record review. MACs shall not use this
message on denials not involving LCDs. For claims reviewed on a postpayment basis,
include the language exactly as contained in the MSN message above if sending the
beneficiary a new MSN. If sending a letter, include the language exactly as contained in
the MSN message above. Message 15.20 currently states:
“The following policies [insert LCD ID# and NCD#] were used when we made this
decision.”(Pub.100-04, chapter 21).
The MACs shall continue to use 15.19 in conjunction with the MSN message 15.20,
where 15.19 is applicable. MACs should, at their discretion, combine these messages if
necessary, but 15.19 shall not be deleted.
In the case where the results of claims sampling are extrapolated to the universe, only
those beneficiaries in the sample need to be notified. In RAC cases, the RAC and MAC
Joint Operating Agreement (JOA) shall specify what information the RAC will supply to
allow the MAC to notify the beneficiary when re-adjudication results in a change to the
initial determination.
