Insurance, HSA and FSA
Coverage is the single biggest lever on what a GLP-1 costs you — the difference between a copay and a four-figure monthly bill. It is also the step most people skip before signing up for a cash-pay compounding subscription.
Do this before anything else. If your plan covers a branded GLP-1 for weight management, that route gives you an FDA-approved medication with trial evidence behind it, usually for less than any cash-pay compounded plan. Thirty minutes on the phone with your insurer is the highest-value half hour in this whole process. Compounding is the fallback when coverage genuinely is not available — not the default starting point.
Getting Coverage: Five Steps
Find out whether your plan excludes weight-loss drugs at all
Many employer plans carve out anti-obesity medication as a category, regardless of your BMI or comorbidities. Call the number on your card and ask specifically: 'Does my plan cover anti-obesity medications, and is Wegovy or Zepbound on the formulary?' A yes to the first and no to the second is a different problem from a blanket exclusion.
Check the formulary tier and the prior authorisation criteria
Even when covered, these drugs usually sit on a high tier behind prior authorisation. The criteria typically mirror the approved indications — BMI 30+, or 27+ with a weight-related condition — and often require documented prior attempts at lifestyle intervention. Ask for the criteria in writing so your prescriber can address each point.
Have your prescriber submit with the documentation the criteria ask for
Most prior authorisation denials are administrative rather than clinical. Weight history, BMI, comorbidity diagnoses with their codes, and prior interventions are what the reviewer is looking for. A provider that handles insurance navigation as part of its service is genuinely earning its fee here.
Appeal a denial — a meaningful share succeed
A first denial is not the end. Plans have internal appeal processes and, beyond those, external review. A letter of medical necessity from your prescriber addressing the specific denial reason is the single most useful document.
If it is genuinely not covered, price the manufacturer programmes before compounding
Novo Nordisk and Eli Lilly both operate direct-purchase and savings programmes for cash-pay patients. Those get you an FDA-approved product. Compare that against compounded pricing before assuming compounded is the only affordable route.
HSA and FSA: What Qualifies
Prescribed medication generally qualifies
Health savings accounts and flexible spending accounts cover qualified medical expenses, and a medication prescribed by a licensed clinician to treat a diagnosed condition generally falls inside that. Several providers we have reviewed advertise HSA/FSA eligibility explicitly — Peak Wellness among them — and telehealth consultation fees are usually eligible too.
Where it gets less certain
Two grey areas worth knowing. First, weight loss for general wellbeing rather than a diagnosed condition has historically not qualified — a diagnosis and a prescription matter. A letter of medical necessity from your prescriber resolves most ambiguity, and is worth requesting up front rather than during an audit. Second, compounded medication: it is prescribed, which is the main test, but some administrators scrutinise it more closely, and at least one provider we reviewed is reported not to accept HSA or FSA at all. Keep your receipts and the prescription record, and ask your plan administrator rather than the seller.
The rules are set by your administrator, not by us
This is general information, not tax advice. Eligibility ultimately depends on current IRS rules and your specific plan documents, and both change. Confirm with your plan administrator before assuming a purchase will be reimbursed — the consequences of getting it wrong land on you, not the provider.

A handful of others among the 325 providers we have reviewed accept insurance for parts of their service — Talkspace and Talkiatry are in-network for behavioural health, and Midi Health is in-network with most major PPO plans for menopause care — but they are not GLP-1 prescribers. For the medication itself, the list above is where insurance actually helps.
