CMS releases Sample Lab ABN

An example of an approved customization of the ABN which can be used by providers of laboratory services can be found at https://www.cms.gov/Medicare/Medicare-General-Information/BNI/ABN.html.

Providers must exercise caution before adding any customizations beyond these guidelines, since changing ABNs too much could result in an invalid notice and provider liability for non-covered charges. Validity judgments are generally made by Medicare contractors, usually when reviewing ABN-related claims; however, any complaints received may be investigated by contractors and/or CMS central or regional offices.
