CMS Pub. 100-04, ch. 30, § 500
Glossary
The following terms are defined only for purposes of this Chapter 30 of the
Medicare Claims Processing Manual.
Advance notice of non -coverage– 42 CFR 418.408(d)(2) states that if
Medicare would be likely to deny payment as not medically reasonable and
necessary, before the service was provided, the physician informed the
beneficiary, or someone acting on the beneficiary's behalf, in writing that the
physician believed Medicare was likely to deny payment for the specific service
and that the beneficiary signed a statement agreeing to pay for that service. This
statement may appear as the notice of non-coverage (e.g.
Advance Beneficiary Notice of Non-coverage (ABN), Form CMS-R-131,
Skilled
Nursing Facility Advance Beneficiary Notice of Non-Coverage (SNF ABN),
Form CMS10055, Home Health Change of Care Notice (HHCCN), Form
CMS-10280), as defined in 42 CFR 411.404.)
Advance Beneficiary Notice of Non-coverage (ABN, Form CMS-R-131) -
Issued by healthcare providers and suppliers to Original Medicare (fee for
service) beneficiaries in situations where Medicare payment is expected to be
denied.
Authorized representative – An individual authorized under State or other
applicable law, e.g., a legally appointed representative or guardian of the
beneficiary (if, for example, the beneficiary has been legally declared
incompetent by a court) to act on behalf of a beneficiary when the beneficiary
is temporarily or permanently unable to act for himself or herself. The
authorized representative will have all of the rights and responsibility of a
beneficiary or party, as applicable. In states which have health care consent
statutes providing for health care decision making by surrogates on behalf of
patients who lack advance directives and guardians, reliance upon individuals
appointed or designated under such statutes to act as authorized
representatives is permissible. The Appointment of Representative, Form
CMS-1696 is available for the convenience of the beneficiary or any other
individual to use when appointing a representative.
For purposes of this chapter, when the term beneficiary is used, for legal
purposes, and the beneficiary has an authorized representative, the use of
either beneficiary or authorized representative are exchangeable of each other,
unless otherwise indicated.
