The short answer
A prescription and an insurance approval are different steps. Before paying for a GLP-1 program, ask your plan whether the exact medication and prescribed use are covered, which authorization form applies, and who will submit it. If a request is denied, get the written reason before deciding whether to correct the application or appeal.

The most useful question is specific: “Does my current benefit cover this drug for this diagnosis, and what documents does my prescriber need?” A provider saying it offers insurance assistance does not answer that question. Our cost guide explains why a program fee can remain payable even when the medication is denied.
Start with the benefit, then the criteria
Some employer plans exclude weight-loss medication. Others cover it subject to clinical criteria. UnitedHealthcare's October 2026 commercial policy explicitly applies to employers that elected weight-loss coverage; it is not a promise to every UnitedHealthcare member1. Ask for the policy attached to your own member number rather than relying on a friend's successful authorization.
Also distinguish a drug's formulation and prescribed purpose. A plan can treat a pill and an injection differently. The current UHC document includes a note that Wegovy tablets are typically excluded, even while listing criteria for several Wegovy products1. An online formulary search alone can therefore leave an important question unanswered.
| What the response says | What to establish next | Useful document |
|---|---|---|
| Prior authorization required | What to establish next: Which clinical criteria apply to this request? | Useful document: Current criteria and request form |
| Information missing | What to establish next: Exactly which record or field is absent? | Useful document: Written deficiency or denial notice |
| Drug nonpreferred | What to establish next: Is an alternative preferred, or is an exception possible? | Useful document: Formulary and exception process |
| Benefit excluded | What to establish next: Does the exclusion apply to the prescribed indication? | Useful document: Benefit booklet and denial explanation |
| Previously approved | What to establish next: When does approval expire and what proves continuation? | Useful document: Authorization letter and renewal criteria |
Prepare a useful packet for your prescriber
Create one folder with the plan's criteria, your medication list, the denial if there is one, and relevant records from previous clinicians. Give your prescriber accurate dates and contact details so records can be requested. If a clinic needs an authorization allowing it to speak for you, complete that before the deadline rather than assuming enrollment covers it.
For an example of what a plan may request, the UHC policy uses a BMI of at least 30, or at least 27 with a weight-related condition, along with lifestyle modification. Its continuation rules differ from its starting rules and include treatment response1. Those figures describe this policy; your prescriber should check your plan rather than copy them into an application by default.
If you changed doctors after pregnancy or moved states, ask the previous office for the relevant chart before the new visit. A short timeline is easier to work with than a long message thread: starting weight and date, prescribed treatments and dates, why they ended, and the records available to support each item. The clinician decides which information is medically relevant. Never add a diagnosis you do not have to fit a form.
A denial is a reason to read, not to guess
Separate a missing record from a disagreement about medical necessity. If the notice says the application omitted a measurement, ask whether a corrected submission is appropriate. If it says the criteria were not met, ask the prescriber to explain which criterion is disputed and what the chart actually shows. Resending the same packet without addressing the stated reason can consume time without changing the decision.
HealthCare.gov describes internal appeals as asking the plan to reconsider its decision. It lists a 180-day filing window after a denial and allows supporting material such as a clinician's letter2. Use the instructions on your own notice to confirm the route and deadline, especially for Medicare, Medicaid or other coverage with a different process.
Keep the original notice, the submitted appeal, delivery confirmation and call notes together. HealthCare.gov recommends preserving records of correspondence and conversations2. For everyday organization, put the next deadline at the top of the folder and note who is responsible for the next action. “The office is handling it” becomes much more useful when it includes a name and a submission date.
What external review can and cannot settle
After an internal appeal, some disputes can go to an independent external reviewer. HealthCare.gov identifies medical-judgment denials among the eligible categories and describes a four-month request window after the relevant final denial; standard reviews generally take no more than 45 days3. Follow the final determination's instructions because the process depends on the plan and state.
An appeal should address the actual reason for refusal. A letter explaining why a medicine would help you is not the same as establishing that the benefit covers it. Ask the plan's assistance service which part of the dispute is reviewable. If you need help understanding the paperwork, HealthCare.gov points to state Consumer Assistance Programs and insurance departments3.
Plan for renewal before the last refill
Record the approval's expiration date as soon as it arrives. Ask your clinic when it wants follow-up records and how it handles a change of insurer or employer. Keep baseline records even after your weight changes; they may be important context for a continuation request. Do not assume a paid annual telehealth subscription guarantees a year of insurance authorization.
For mothers planning another pregnancy, restarting after a break, or coordinating nursing with treatment, the medication plan needs a separate clinical conversation. Insurance paperwork does not decide whether treatment is appropriate today. Our pregnancy guide and breastfeeding guide explain the questions to bring to that visit. Finish with two clear plans: what your clinician recommends, and what your insurer has actually agreed to pay.
What this guidance can establish
The evidence here is administrative: published insurer criteria and federal consumer guidance, not a study predicting your chance of approval. The UHC policy is an example from one commercial program. Your benefit documents and written decision determine which criteria and appeal route apply to you.
