Attending Physician vs. Hospice Medical Director Role

The attending physician is the clinician the patient personally identifies as having the most significant role in their medical care, while the hospice medical director is the physician the hospice designates to oversee the medical component of its program and to support certification of terminal illness. The attending is chosen by the patient and may practice outside the hospice; the medical director must be a hospice employee or contractor (42 CFR 418.3, https://www.ecfr.gov/current/title-42/chapter-IV/subchapter-B/part-418/subpart-A/section-418.3; 42 CFR 418.102, https://www.ecfr.gov/current/title-42/chapter-IV/subchapter-B/part-418/subpart-D/section-418.102).

Under the definition at 42 CFR 418.3, an attending physician is a doctor of medicine or osteopathy, a nurse practitioner, or a physician assistant who is identified by the patient, at the time of election, as having the most significant role in the determination and delivery of their medical care ^[1]. Having an attending is optional — a patient may elect hospice without one. The hospice medical director must be a doctor of medicine or osteopathy who is an employee of, or under contract with, the hospice and who has responsibility for the medical component of the hospice's patient care program (42 CFR 418.102)^[2]. For certification, the medical director (or a physician designee if the medical director is unavailable) or a physician member of the IDG reviews the clinical information and provides the written certification of the six-month prognosis; the initial certification also requires the attending physician's certification when the patient has an attending (42 CFR 418.22)^[3]. A nurse practitioner or physician assistant serving as attending may deliver and, where applicable, bill for care, but may not certify terminal illness.

Certification validity turns on getting the right signatures from the right roles, and the most common error is conflating the attending role with certifying authority. When a patient's attending is a nurse practitioner or physician assistant, that clinician cannot sign the certification of terminal illness — a hospice physician must — and treating the NP's attestation as a certification will not survive review. The reverse error is omitting the attending's signature on the initial certification when the patient does have an attending physician, which invalidates the first period. Because the attending is patient-designated, the admission record must document in writing whether an attending exists and who it is, so the certification packet reflects the correct signatories from the first period. The regulatory distinction requires the medical director's certifying role and the attending's clinical role to remain clearly separated to avoid both denials and coordination gaps.
