I have the plan documents and the written criteria, which took two calls to obtain.
I want a method I can write down and repeat, not a rule of thumb.
I would rather over-engineer this than discover a problem later, within reason.
Which parts of this are load-bearing and which parts are habit?
The short version: get the criteria, evidence each one in the record, submit with the documentation attached, and appeal a denial with the reason addressed.
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.
| Line | Brand, insured | Compounded, subscription | Research-grade, self-tested |
|---|---|---|---|
| Product | Copay × 12 | Monthly fee × 12 | Vials × unit price |
| Consultation | Covered or copay | Bundled | Not applicable |
| Monitoring labs | Often covered | Usually not | Self-funded |
| Independent testing | Not applicable | Optional | Essential; per lot |
| Shipping | Pharmacy | Included | Per order |
| Dominant cost | Copay structure | Subscription fee | Testing |
Stated carefully, 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.
Medical policies stating prior-authorisation criteria are published by plans and are obtainable before submission.
Get the criteria first. A request written blind is a request written badly.
Analytical standards and reagents with traceable certificates. Every quantitative result you read inherits the accuracy of the standard behind it.
Shop standardsAnswering this needs the plan, since criteria vary and a general answer is not actionable.
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.
Track the deadlines. Appeal windows are finite, and a well-founded appeal filed late is worth nothing at all.
Appeal windows and renewal periods are defined in plan documents and are strictly applied.
The denial reason is the appeal specification. Address it directly.
The relevant point is that most denials cite a missing element rather than a clinical disagreement, and missing elements are fixable.
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.
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.
Attach everything on the first submission. Incomplete is the commonest denial.

The denial letter states the reason. That reason is the specification for the appeal.
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.
Evidence every criterion in the dated record, not in a covering letter.
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.
