Accepted answer
Those are two different denials with two different remedies, and the second one is the wall. Sort out which you actually have before spending another evening.
| Denial type | What it means | Remedy | Realistic odds |
|---|
| PA criteria not met | The drug is covered; your documentation did not satisfy a criterion | Fix the documentation and resubmit, or internal appeal with the missing element | Good. Most of these are documentation gaps |
| Formulary exclusion (non-preferred) | Covered category, but this product is off-list in favour of an alternative | Formulary exception request: alternatives ineffective, harmful, or contraindicated for you | Moderate. Depends entirely on the alternatives argument |
| Quantity limit exceeded | Dose or days-supply outside the edit | Quantity-limit exception; often just a corrected sig | Good, and frequently misdiagnosed as a necessity denial |
| Benefit exclusion | The plan document does not cover the category at all | Not a clinical appeal. This is a plan-design question | Poor through appeals. The route is the plan sponsor |
Why the distinction is decisive. Internal and external review test whether a decision was correct under the terms of the plan. If the plan document says the plan does not cover pharmacotherapy for weight reduction, then denying it is the plan working as written, and no reviewer — internal, external, or judicial — will rewrite the contract. That is why the second sentence in your letter matters more than the first.
Establish which one you have. Ask HR or the plan administrator for the summary plan description and, if you want to be thorough, the plan document itself. Read the exclusions section. There are three possibilities: an explicit exclusion of weight-loss pharmacotherapy (you are behind a benefit exclusion); no such exclusion, in which case the letter's second sentence is recycled boilerplate and you are actually in a formulary dispute; or an exclusion with carve-outs, which is increasingly common and where the whole game is played. Carve-outs are typically worded around a comorbidity, a BMI threshold, or enrolment in the plan's own weight-management vendor programme. If a carve-out exists and you meet it, cite the plan's own language back at them by section number. That is a much stronger appeal than any clinical argument.
The appeal ladder
- Internal appeal. For an ERISA plan you generally have at least 180 days from the adverse determination, and the plan must decide a pre-service appeal within 30 days. The reviewer must not be the person who made the original decision, nor their subordinate, and for a medical-necessity issue must consult an appropriately qualified clinician. Request a peer-to-peer with the reviewing physician; a fifteen-minute prescriber call resolves a meaningful fraction of these.
- Second-level internal appeal if the plan offers one. Some do, some do not; the letter will say.
- External review. An independent review organisation, with reviewers who have no financial relationship to the plan, re-decides the question. Its determination is binding on the plan. You generally have four months from the final internal denial, and the standard timeframe is 45 days (72 hours expedited).
The critical limit on external review: it is available for adverse benefit determinations involving medical judgement, and for rescissions of coverage. It is not available for a contractual exclusion. A denial that turns purely on "the plan does not cover this category" is generally not eligible, and an IRO will decline it. This is the specific reason your self-funded status matters: a self-funded ERISA plan uses the federal external-review process rather than your state's, and it is not bound by state coverage mandates. If your state passed a law requiring anti-obesity medication coverage, it very likely does not reach your plan.
Ask for the documents you are entitled to. In writing: the specific plan provisions relied on, the internal rules or criteria applied, any clinical review criteria, and the reviewer's qualifications. Under ERISA claims-procedure rules a plan must provide these on request free of charge. A plan that cannot produce the criteria it applied has a procedural problem, and procedural failures are a real basis for relief in a way that "I disagree" is not.
If it is a true benefit exclusion. Stop appealing and change target. The decision-maker is the employer as plan sponsor, and benefit design changes at renewal. That means HR, the benefits committee, and any employee resource group with a channel to them. Coverage of this category has moved fast at large employers, and internal advocacy has a far better hit rate than a fifth appeal letter. Ask specifically whether the plan has considered adding a managed pathway with clinical criteria, since "add it with guardrails" is a much easier proposal for a benefits team to approve than "add it".

4The medical-judgement limit on external review is the part almost every online guide gets wrong. – Dr_Rosalind_Achebe 9 months ago 3Our plan added a carve-out at BMI 35 with a comorbidity and never announced it. Reading the SPD is genuinely worth an evening. – micron22 7 months ago add a comment
