Medicare Claims Processing Manual (Pub. 100-04), Ch. 30 § 50
Advance Beneficiary Notice of Non-coverage (ABN)
50 - Advance Beneficiary Notice of Non-coverage (ABN)
(Rev. 10862; Issued: 07-14-21; Effective: 10-14-21; Implementation: 10-14-21)
A. General Statutory Authority - Applicability to Limitation on Liability (LOL)
Section 1879 of the Act (where the LOL provisions are located) requires a healthcare
provider or supplier (i.e. notifier) to notify a beneficiary in advance of furnishing an item
or service when s/he believes that items or services will likely be denied by Medicare for
any of the reasons specified in the statutory provision in order to shift financial liability to
the beneficiary for the denial. For example, advance notice is required if the item or
service may be denied as not reasonable and necessary under §1862(a)(1) of the Act or
because the item or service constitutes custodial care under §1862(a)(9) of the Act.
Notice (e.g., the ABN) is a way for healthcare providers or suppliers to establish
beneficiary knowledge of non-coverage and therefore, shift financial liability for these
items or services if Medicare denies the claim.
B. Compliance with Limitation on Liability Provisions
A notifier who fails to comply with the ABN instructions risks financial liability and/or
sanctions. LOL provisions shall apply as required by law, regulations, rulings and
program instructions. Additionally, when authorized by law and regulations, sanctions
under the Conditions of Participation (COPs) may be imposed.
The Medicare contractor may hold any healthcare provider or supplier who either failed
to give notice when required, or gave defective notice, financially liable. A notifier who
can demonstrate that s/he did not know and could not reasonably have been expected to
know that Medicare would not make payment will not be held financially liable for
failing to give notice. However, a notifier who gave defective notice may not claim that
s/he did not know or could not reasonably have been expected to know that Medicare
would not make payment, as the issuance of the notice is clear evidence of knowledge. A
notifier who cannot demonstrate that adequate advance notice was furnished to the
beneficiary will not be able to use the provisions in section 1879 of the Act to transfer
financial liability to the beneficiary.
