Understanding ABNs and when they’re needed is essential for Medicare billing. An Advanced Beneficiary Notice (ABN) is used when a service may not be covered, so the patient can decide whether to accept potential liability. If the situation arises where you did not obtain an ABN at all, that needs to be clearly indicated because without an ABN, the provider typically cannot bill the patient for a non-covered service.

The best choice communicates that the ABN was not obtained because you forgot to have the patient sign one. This directly flags the missing step, which is what the modifier or note should reflect. The other statements either imply an ABN was already obtained or that an ABN wasn’t needed, or they indicate the ABN is invalid—none of which describes the failure to obtain the ABN in the first place.
