Medicare Claims Processing Manual (Pub. 100-04), Ch. 30 § 50.11
ABNs for Medical Equipment and Supplies Claims Denied
50.11 - ABNs for Medical Equipment and Supplies Claims Denied
Under §1834(j)(1) of the Act (Because the Supplier Did Not Meet
Supplier Number Requirements)
(Rev. 10862; Issued: 07-14-21; Effective: 10-14-21; Implementation: 10-14-21)
To qualify for waiver of the RR under §1834(j)(4)(A) and §1879(h)(1) of the Act
(unassigned and assigned claims, respectively) for medical equipment and supplies for
which payment will be denied due to failure to meet supplier number requirements under
§1834(j)(1) of the Act, the ABN must state that Medicare will deny payment for any
medical equipment or supplies because the supplier does not have a supplier number.
The supplier should keep the ABN on file for documentation that the beneficiary has
knowledge of this particular denial and that the beneficiary accepts financial liability. This
relieves the supplier, which has duly notified a beneficiary of its lack of a supplier
number and the fact that Medicare will not pay, from the necessity of obtaining a signed
agreement from the beneficiary every time the beneficiary does business with the
supplier.
Exception to ABN Requirement
A supplier which can show that it did not know and could not reasonably have been
expected to know that a customer was a Medicare beneficiary, or that a customer was
making a purchase for a Medicare beneficiary, can seek protection under the LOL
provision or, in the case of unassigned claims, under the applicable RR provision,
§1834(j)(4) of the Act. Below are situations where the supplier may seek protection
under the LOL provision or the RR provision:
• If the supplier can show that a person who is not a Medicare beneficiary made a
purchase on behalf of a person who is a Medicare beneficiary and did not apprise the
supplier of the fact that the purchase was being made on behalf of a Medicare
beneficiary, the supplier may be protected.
• If the supplier can show that a Medicare beneficiary who made a purchase did not
identify himself or herself as a Medicare beneficiary and that the person’s age or
appearance was such that the supplier could not reasonably have been expected to
know or surmise that the person was a Medicare beneficiary, the supplier may be
protected. These protections are meant for an honest supplier in the rare case where a
Medicare beneficiary who is relatively youthful, healthy and able in appearance does
not identify himself or herself as a beneficiary and the supplier understandably does
not surmise that he or she might be a Medicare beneficiary.
If the involved Medicare beneficiary is found to be obviously aged and/or disabled, such
that any adult person working for a supplier would reasonably surmise that he or she
could be a Medicare beneficiary, the supplier’s allegation may not be accepted. If the
beneficiary purchased an item which would strongly suggest to any reasonable adult
person working for a supplier that the beneficiary is aged and/or disabled, the supplier’s
allegation may not be accepted.
• If a supplier can show that a customer, who is a Medicare beneficiary or was making
a purchase for a Medicare beneficiary and did not identify him/herself accordingly to
the supplier, was on notice of the necessity to so self-identify, the beneficiary may be
held liable, in which case the supplier could collect from the beneficiary.
Given the possible difficulty of showing conclusively that it did not know and could not
reasonably have been expected to know that a customer was a Medicare beneficiary, or
that a customer was making a purchase for a Medicare beneficiary, a supplier would be
well advised to consider using signage, giving public notice alerting customers that they
need to inform the supplier if they are a Medicare beneficiary or are making a purchase
for a Medicare beneficiary. If a supplier which does not have a supplier number provides
adequate public notice to a Medicare beneficiary before medical equipment or supplies
are furnished (e.g., by means of clearly visible signs, and if the adequacy of such public
notice is not disputed by the beneficiary) the supplier can qualify for waiver of the
Refund Requirements. Such public notices must be such that Medicare beneficiaries:
1. Are virtually certain to see them before purchasing or renting Medicare-covered
medical equipment or supplies from the supplier (that is, they are posted in places
where they are most likely to be seen by the target audience), and
2. May reasonably be expected to be able to read them and understand them.
Therefore, such public notices must be readily visible, in easily readable plain language,
in large print, and would have to be provided in the language(s) commonly used in the
locality.
Do not hold any beneficiary who cannot read any such public notice of a supplier to be
properly notified in advance by the supplier that Medicare will not pay. If a supplier
alleges that it provided adequate public notice to Medicare beneficiaries but a beneficiary
disputes the allegation, in the absence of conclusive evidence in favor of the supplier, do
not hold the beneficiary to be properly notified in advance by the supplier that Medicare
will not pay; hold the supplier liable. The RR provision that the beneficiary must agree
to pay for the item or service makes the use of signage without an ABN a risk for the
supplier. It would be in a supplier’s best interest to issue ABNs advising beneficiaries
that they will have to pay for supplies and to post public notices in its store(s) which
inform beneficiaries of the fact that it is not a Medicare enrolled supplier, and that claims
for supplies purchased from that supplier will be denied payment by Medicare. The use
of notices in conjunction with public notices will provide maximum protection to
suppliers as well as more surely providing proper notice to beneficiaries so that they can
make informed consumer decisions.
Medicare denial of payment on the basis of a supplier’s lack of a supplier number applies
to all varieties of medical equipment and supplies and to all Medicare beneficiaries
equally. Therefore, the usual restriction on routine notices to all beneficiaries does not
apply in this case.
