Answer: The practice should have a witness present to document that the patient refused to sign the waiver. The witness, who may be an employee of the practice, then signs and dates the waiver in place of the patient and makes a note indicating that he witnessed the refusal to sign. At this point, the service may be provided and the patient may be held responsible for the charges.
Many family practices misunderstand when a patient needs to sign an ABN. These waivers should be signed when the physician recommends a service or procedure that is covered by Medicare in some instances but might not be covered under current circumstances. This might occur, for instance, if a diagnosis does not support Medicare's standard of medical necessity for the procedure, or if a screening exam (e.g., screening mammography, 76092) is performed more frequently than Medicare allows.
ABNs are not necessary for services that are never covered by Medicare, like annual preventive exams. CMS recently revised the ABN form that practices should use with Medicare patients. Copies of the form are at http://codinginstitute.com/news/-article9.html.
