A. Other Considerations During ABN Completion
1. Beneficiary Changes His/her Mind
If after completing and signing the ABN, a beneficiary changes his/her mind, the notifier
should present the previously completed ABN to the beneficiary and request that the
beneficiary annotate the original ABN. The annotation must include a clear indication of
his/her new option selection along with the beneficiary's signature and date of annotation.
In situations where the notifier is unable to present the ABN to the beneficiary in person,
the notifier may annotate the form to reflect the beneficiary's new choice and
immediately forward a copy of the annotated notice to the beneficiary to sign, date, and
return.
In both situations, a copy of the annotated ABN should be provided to the beneficiary as
soon as possible. If a related claim has been filed, it should be revised or cancelled if
necessary to reflect the beneficiary’s new choice.
2. Beneficiary Refuses to Complete or Sign the Notice
If the beneficiary refuses to choose an option and/or refuses to sign the ABN when
required, the notifier should annotate the original copy of the ABN indicating the refusal
to sign or choose an option and may list witness(es) to the refusal on the notice although
this is not required. If a beneficiary refuses to sign a properly delivered ABN, the notifier
should consider not furnishing the item/service, unless the consequences (health and
safety of the patient, or civil liability in case of harm) are such that this is not an option.
In any case, the notifier should provide a copy of the annotated ABN to the beneficiary,
and keep the original version of the annotated notice in the patient’s file.
