An appeal contests a decision the plan already made. Start by identifying which system governs the plan, since employer self-funded coverage, fully insured coverage, and Medicare drug coverage run on different ladders and different clocks. Then file an internal appeal within the stated window, and escalate to independent external review if that fails. Excluded categories are the exception, and they rarely move.
Read the notice before writing anything
An adverse determination has to state the specific reason, identify the rule or criterion relied on, and explain how to challenge it. That letter sets the entire strategy. A refusal for missing documentation is answered with documents. A refusal because a preferred agent was never tried is answered with dated proof of that trial. A statement that the plan does not cover drugs for chronic weight management is not a clinical decision at all, and an appeal arguing medical necessity against it will lose on procedure.
The letter also carries the filing deadline and the address or portal for submission. Missing a deadline is the most common way a winnable case ends, and extensions are not usually available.
Work out which rulebook applies
Four systems cover most people, and they behave differently.
Self-funded employer coverage is governed by federal law, with the employer bearing the cost and the benefit manager processing claims. Fully insured employer and individual coverage is regulated at the state level and carries a state external review process. Medicare drug coverage runs a defined redetermination sequence with its own timetables. Medicaid managed care runs a state fair hearing route alongside the plan’s own appeal.
The distinction is not academic. External review by an independent organization is available in most of these systems, and it is the stage at which a decision passes out of the plan’s hands. Knowing whether that stage exists changes how much effort the earlier levels deserve.
| Level | Who decides | What it can change |
|---|---|---|
| Exception request | Benefit manager reviewer | Coverage of a non-preferred product |
| Internal appeal, first level | A reviewer not involved in the original call | Criteria and documentation decisions |
| Internal appeal, second level | Plan medical staff, where offered | The same ground, with fuller evidence |
| External review | Independent review organization | Medical necessity, binding on the plan |
| Expedited review | Same bodies, compressed timetable | Urgent cases only |
| Benefit design | The employer or plan sponsor | Whether the category is covered at all |
The first internal appeal
A first-level appeal should be short and targeted. State the member details and claim reference, quote the reason given, and answer that reason specifically. Attach chart notes with dates, pharmacy fill history where prior therapy is at issue, and a letter from the prescriber describing the clinical picture in the plan’s own vocabulary rather than in general terms.
Reviewers respond to documents, not adjectives. Research on overturned claim denials points at completeness and specificity of the submitted record as the factors associated with reversal, which matches what practices report anecdotally. A note recording a weight-related condition, dated before the request, does more work than three paragraphs of argument.
Keep a record as the file moves
Appeals cross several desks, and material goes missing between them. Keep a dated log of every call with the name of the person spoken to, a copy of everything submitted, and proof of the date each submission was sent. Request the criteria document the plan applied, which members are entitled to receive, and read it as a checklist rather than as a rejection. Where a second-level internal review exists, that record becomes the basis for the next filing without rebuilding anything from memory.
External review, and why it matters
External review moves the file to reviewers with no financial relationship to the plan, and their determination binds the plan in the systems where it applies. It is generally available only after internal appeals are exhausted, though expedited paths can run in parallel in urgent cases. This is the stage where medical necessity disputes get their fairest hearing, and it is worth preserving by filing everything earlier in the sequence on time.
What external review cannot do is rewrite the contract. If the plan document excludes a category, an independent reviewer applies that document. The path there runs through the employer’s benefits committee at renewal, not through an appeal.
Treatment while the process runs
Appeals take weeks, and a course of treatment usually cannot pause neatly for the outcome. Some people bridge the gap with the manufacturer’s self-pay channel, which keeps them on the approved product. Others price a supervised cash program such as Ro, LifeMD, or FormBlends and then decide whether finishing the appeal is still worth the effort. Compounded semaglutide, which those programs commonly supply, is not an FDA-approved product, and that fact belongs in the comparison alongside the monthly price.
Either way, keep paying attention to the calendar. Bridging privately does not extend an appeal deadline.
When weighing those bridge options, the model behind the price matters as much as the number itself. Independent practices such as Henry Meds and HealthRX keep public pages on cash pricing and supervision for Wegovy and its compounded alternatives, and the ones worth shortlisting spell out dose adjustment and laboratory follow-up rather than quoting a monthly figure alone.
Questions people ask
How long does an appeal take?
Standard internal appeals are typically decided within thirty to sixty days depending on the system and whether the service has already been received. Expedited review compresses that to a matter of days where delay would seriously jeopardize health. The notice states the applicable timetable, and those timetables are enforceable.
Does the prescriber have to write the appeal?
Not always, but clinical support changes outcomes. Members can file on their own behalf and can appoint a representative. In practice the strongest submissions pair a member letter setting out the history with a prescriber letter addressing the specific criterion the plan cited. Splitting the work that way plays to what each side actually knows.
Can an appeal succeed against a category exclusion?
Very rarely. An appeal argues that a rule was misapplied, and an exclusion applies no clinical rule. Survey work shows broad public support for covering weight management medication, but coverage remains a purchasing decision. Changing it means changing next year’s benefit design rather than winning this year’s case.
What if the drug becomes unavailable during the process?
Supply problems are a separate track from coverage. Approvals are written for a named product, so a substitution generally needs its own authorization even when the original is approved. Confirming availability before filing avoids winning an appeal for something the pharmacy cannot dispense.
