Answer
The short answer
Yes on every route, and on two of them without paperwork. A Part D prescriber can act without being an appointed representative. In an urgent commercial claim, a treating professional must be allowed to act.
Someone other than you, on all three routes. What differs is the paperwork, and on two of them the paperwork can be skipped entirely in the situations where it matters most.
This is worth sorting out early rather than at the end of a filing window, because the wrong answer here costs days you do not have.
A plan may not shut an authorized representative out. Its procedures must not preclude an authorized representative from acting on your behalf in pursuing a claim or an appeal.
It may, though, set up reasonable procedures for checking that someone really is authorized — a form, usually. There is one carve-out, and it is the important one: in a claim involving urgent care, a health care professional with knowledge of your medical condition must be permitted to act as your authorized representative. The plan does not get to slow that down with its verification process.
There is a second lever alongside it. Any claim a physician with knowledge of your condition determines is a claim involving urgent care has to be treated as one. Your prescriber's judgment on urgency is not a request the plan weighs; the regulation makes it the answer.
For the things that matter, no. The agency states it directly: your prescribing physician or other prescriber may request a coverage determination, a redetermination or an independent review entity reconsideration on your behalf without having to be an appointed representative.
That covers the first two levels of appeal and the original coverage request. It is the single most useful sentence on this page, because the prescriber's office is usually the party holding the clinical documentation anyway.
Anyone who is not your prescriber does need appointing. A representative is defined as someone either appointed by you or authorized under state law to act for you, and unless the rules say otherwise that representative has all of your rights and responsibilities through the whole appeals process.
Longer than most people assume, so it is worth filing one properly rather than repeatedly. The federal appointment form says the appointment is valid for one year from the date both people sign it, and a completed form can be used for other appeals or actions during that year.
It also says that unless revoked, the representation is valid for the duration of the claim, appeal, grievance or request it was filed for. So the one-year limit governs reuse on new matters, not the life of the matter you filed it on.
One practical note if you are downloading it: the form's own landing page carried a notice, when we read it, that an updated version was awaiting approval and that the current form — or any similar conforming written instrument — may be used meanwhile.
The managed care appeal rules speak throughout of the enrollee or the enrollee's authorized representative, and give both the same filing rights: the plan appeal within 60 calendar days of the date on the notice, and then a state fair hearing.
The states set the mechanics of appointing that representative, and they differ. Where we have published a page for your state, the appeal route we read from that state's own documents is on it.
On Part D, to file. Not to send records to you, not to call the plan — to submit the coverage determination or redetermination request itself, because the rules let them and the clock on an exception does not start until their supporting statement arrives.
On a commercial plan, to say whether the claim is urgent, since that determination is theirs to make and it changes both the deadline and the paperwork. And on any route, to send you the criteria document the decision was made against, which you are entitled to have free of charge.
This page describes who the rules allow to file. It does not advise you on what to ask a prescriber to write, and no page here does.
What to say to the prescriber's office
My plan denied [drug name] on [date]. If this is Medicare Part D, the rules let a prescriber file the redetermination directly without being an appointed representative — could your office file it? If this is a commercial plan, could you tell me whether you consider this claim urgent, and if so act as my authorized representative? Either way, please send me the clinical criteria the plan decided against.
Write down who you spoke to and the date. If the office says it cannot file, ask what it needs from you to be able to — usually it is a signed form and nothing else.
If something here decides anything for you, read the source rather than our summary of it. These are the documents we opened, and the month we opened them.
A commercial plan cannot lock a representative out, and in an urgent case cannot delay one. Its procedures must not "preclude an authorized representative of a claimant from acting on behalf of such claimant in pursuing a benefit claim or appeal of an adverse benefit determination," and while a plan "may establish reasonable procedures for determining whether an individual has been authorized to act on behalf of a claimant," that is subject to a condition: "in the case of a claim involving urgent care... a health care professional... with knowledge of a claimant's medical condition shall be permitted to act as the authorized representative of the claimant."

Your prescriber decides whether the claim is urgent, and that decision binds the plan. "Any claim that a physician with knowledge of the claimant's medical condition determines is a 'claim involving urgent care' within the meaning of paragraph (m)(1)(i) of this section shall be treated as a 'claim involving urgent care' for purposes of this section."

On Medicare Part D a prescriber needs no appointment at all for the steps that matter. The agency states: "The enrollee's prescribing physician or other prescriber may request a coverage determination, redetermination or IRE reconsideration on the enrollee's behalf without having to be an appointed representative."

Anyone else does need appointing, and an appointed representative then stands in your shoes throughout. "Representative means an individual either appointed by an enrollee or authorized under State or other applicable law to act on behalf of the enrollee in filing a grievance, obtaining a coverage determination, or in dealing with any of the levels of the appeals process. Unless otherwise stated in this subpart, the representative has all of the rights and responsibilities of an enrollee."

The federal appointment form is reusable for a year, and open-ended on the matter it was filed for. "An appointment of a representative is considered valid for one year from the date this form is signed by both the person appointing a representative and the appointed representative. A completed form can be used for other appeals or actions during the one-year period it's valid. Unless revoked, the representation is valid for the duration of the claim, appeal, grievance, or request for which it was filed."

In Medicaid managed care the enrollee's authorized representative has the same filing right as the enrollee. "Following receipt of a notification of an adverse benefit determination by an MCO, PIHP, or PAHP, an enrollee has 60 calendar days from the date on the adverse benefit determination notice in which to file a request for an appeal to the managed care plan," and the rules give that right throughout to "an enrollee, or the enrollee's authorized representative." The plan may have "only one level of appeal for enrollees" before the state fair hearing opens.

Whoever files, the criteria document is available to you free of charge. On appeal the plan must "Provide that a claimant shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the claimant's claim for benefits."
