I have the plan documents and the written criteria, which took two calls to obtain.
I can find plenty of assertions about this and almost no reasoning, which is usually a sign that nobody has checked.
Assume no laboratory access beyond what I can pay a third party for.
Concretely, what should I do, and how would I know afterwards whether I did it right?
Answer first: a prior authorisation is a documentation exercise against published criteria, and it is won or lost on whether the record contains the required elements.
Where prerequisite therapy is required, the record needs the agent, the dates, the dose and the reason it was stopped. "Tried and failed" without those four elements is not documentation.
The relevant detail is that approvals expire. Note the renewal date when the approval arrives, because a lapse mid-treatment is administratively identical to a fresh denial.
Peer-to-peer review is a standard step in utilisation-management processes and resolves a meaningful share of disputes.
Get the criteria first. A request written blind is a request written badly.

Visit GL BiochemStart by obtaining the criteria before the request is submitted, because a request written blind is a request written badly.
Obtain the medical policy for the specific drug and plan first. It lists the required diagnosis codes, thresholds, documented durations and any prerequisite therapy, and it is the checklist the reviewer works from.
It helps to be literal here: the denial letter states a specific reason. The appeal should address that reason first and explicitly, with the missing evidence attached, rather than restating the original case.
Evidence every criterion in the dated record, not in a covering letter.
Peer-to-peer review is available in many systems and is underused.
Each criterion must be evidenced in the clinical record, dated, before the request. A criterion asserted in a covering letter but absent from the notes is the commonest reason for a denial.
Track the deadlines. Appeal windows are finite, and a well-founded appeal filed late is worth nothing at all.
Attach everything on the first submission. Incomplete is the commonest denial.
This is a paperwork problem with a paperwork solution, and framing it that way is the most useful thing anyone can do.
Submit the supporting documents with the request rather than waiting to be asked. Requests denied for insufficient information are denials that a complete submission would have avoided.
A substantial proportion of denials cite incomplete documentation rather than clinical non-eligibility, which is why complete first submissions matter.
Diarise the renewal date the moment approval arrives.

The honest answer is that the process rewards preparation and punishes improvisation.
A peer-to-peer review — the prescriber speaking to the plan's reviewer — is available in many systems and resolves a meaningful proportion of denials that a written appeal would not.
A prescriber has to submit the request; this is a description of what makes one succeed, not a substitute for one.
The denial reason is the appeal specification. Address it directly.

Ask PeptideStack is a static archive. Posting is closed, but the norms are worth stating: answer the question that was asked, show your working, cite the trial or the certificate, and say plainly where the evidence runs out.
