CMS Pub. 100-04, ch. 30, § 50.12
ABNs for Claims Denied in Advance Under §1834(a)(15) of the
Act
(Rev. 10862; Issued: 07-14-21; Effective: 10-14-21; Implementation: 10-14-21)
A. Mandatory
A request for an advance determination of coverage of medical equipment and supplies is
mandatory under §1834(a)(15)(C)(i) & (ii) of the Act when:
• The item is listed by the Secretary as being subject to unnecessary utilization in your
contractor’s service area under §1834(a)(15)(A); or
• The supplier is listed by the Secretary under §1834(a)(15)(B) of the Act as a supplier
who has submitted a substantial number of claims, which have been denied as not
medically reasonable and necessary under §1862(a)(1) of the Act or the Secretary has
identified a pattern of over utilization.
In cases in which an advance coverage determination is mandatory, an ABN must be
issued to the beneficiary prior to furnishing the item. If the advance coverage
determination has not been received, or if the determination is that Medicare will not pay
for the care, an ABN is required prior to furnishing the requested item.
B. Optional
A request for an advance determination of coverage of medical equipment and supplies is
optional under §1834(a)(15)(C)(iii) of the Act when the item is customized and either the
beneficiary or the supplier requests an advance determination. In cases where an advance
coverage determination is optional and the beneficiary requests such a determination, an
ABN must be furnished prior to furnishing the requested item.
Every supplier is expected to know whether or not an advance coverage determination is
required for Medicare payment. The presumption of that supplier’s knowledge becomes
non-rebuttable after a single denial under §1834(a)(15) of a claim by a particular supplier.
