50.9 - Effects of Lack of Notification, Medicare Review and Claim
Adjudication
(Rev. 10862; Issued: 07-14-21; Effective: 10-14-21; Implementation: 10-14-21)
A. Beneficiary Liability
A beneficiary who has been given a properly delivered ABN and agrees to pay may be
held liable. The charge may be the healthcare provider or supplier’s usual and customary
fee for that item or service and is not limited to the Medicare fee schedule. If the
beneficiary does not receive proper notice when required, s/he is relieved from liability.
Notifiers may not issue ABNs to shift financial liability to a beneficiary when full
payment is made through bundled payments. In general, ABNs cannot be used where the
beneficiary would otherwise not be financially liable for payment for the service because
Medicare made full payment.
B. Healthcare Provider or Supplier Liability
A notifier will likely have financial liability for items or services if s/he knew or should
have known that Medicare would not pay and fails to issue an ABN when required, or
issues a defective ABN. In these cases, the notifier is precluded from collecting funds
from the beneficiary and is required to make prompt refunds if funds were previously
collected. Failure to issue a timely refund to the beneficiary may result in sanctions.
A notifier may be protected from financial liability when an ABN is required if s/he is
able to demonstrate that s/he did not know or could not reasonably have been expected to
know that Medicare would not make payment.
