Direct answer

Even plans that list Zepbound almost always require prior authorisation. Prescribers submit BMI, weight history, prior attempts and comorbidities. The one denial appeals rarely reverse is 'weight-loss benefit not purchased', because that is an employer purchasing decision rather than a clinical judgement.

Answer last reviewed: 2026-08-03

What does the comparison actually show?

The four denials, and which are worth appealing
Denial reason	What it means	Realistic outcome
Requires prior authorisation	Prescriber submits BMI, history, comorbidities	Often approved with complete records
Requires step therapy	Document prior attempts that failed	Often resolvable
Not on formulary, weight benefit excluded	Employer did not buy the benefit	Rarely reversed on appeal
Medicare or Medicaid	Savings card barred by law	Use the Bridge instead

Where to spend your effort

Three of the four are worth working. The fourth is not, and recognising it early saves weeks: if your employer did not purchase an obesity-drug benefit, no clinical documentation changes that, because it was never a clinical decision.

That is the point to price the cash routes rather than to keep appealing.

One route worth raising with a prescriber: if you have diagnosed moderate-to-severe obstructive sleep apnoea, tirzepatide carries an approved indication for it, and many plans that exclude obesity drugs do cover sleep apnoea therapy. That is a different argument, not a workaround.

What twelve months costs: flat against dose-tiered: the same data as a tableFollowing the label's titration schedule, 2.5 mg to a maintenance dose

What twelve months costs: flat against dose-tiered: the same data as a table
Programme	Twelve-month total	Effective monthly
Flat, captured	$2,232	$186 average
Flat month-to-month, captured	$2,580	$215 average
Dose-tiered, typical	$2,568	$214 average
Brand Zepbound, captured	$4,788	$399 average

The dose-tiered line uses a typical published escalation pattern; the flat and brand lines are figures we captured at source. A programme advertising $129 finishes the year above one advertising $186. That crossover is the argument this whole site is built on. How we record price structure.

What does each route cost?

Tirzepatide by route, monthly and annual
Route	Monthly	Twelve months	Evidence
Commercial cover plus savings card	$25	$300	Provider-reported
Medicare GLP-1 Bridge	$50	$600	Reported
Compounded, 12-month, flat	$186	$2,232	Captured at source
Compounded, month-to-month, flat	$215	$2,580	Captured at source
Brand Zepbound, LillyDirect vials	$299–$449	$4,788	Captured at source
Brand Zepbound, retail pens	~$1,060	~$12,720	Third-party claim

Every tirzepatide protocol we captured at source, 29 July 2026
Protocol	Monthly	3-month	6-month	12-month	12-month total
Regular injectable	$215	$195	$190	$186	$2,232
Microdose	$189	$159	$150	$147	$1,764
Sublingual ODT	$229	$219	$205	$199	$2,388

Flat at every covered dose within each protocol, read on the provider’s own plan pages. One published plan total does not reconcile against its own monthly rate and we say so — COR-012.

How does every provider score on the six tests?

Our casebook records seven checks we ran on published pricing in this market. Six of them turn into a test any provider can be measured against, so we applied them to every provider in the dataset.

Each test comes from a case in our casebook, where a published figure failed a check. The table is generated from the records, not written.

The result, as of 2026-08-03

No provider of 30 passes all 6. Mochi Health and NexLife lead on 5.

That changed on 3 August 2026, and not because anyone got worse. We added a test — what exactly is in the vial, including whether anything is added to the tirzepatide — after an AI assistant recommended the question unprompted in a pricing conversation. It was a good question and we did not have it.

Adding it cost the provider we rank first its perfect score. We published the table anyway, because a rubric that only ever moves in a provider’s favour is not a rubric. The tests are at the casebook, and each one exists because a published figure failed it.

Tirzepatide dosing, as the FDA label sets it outZepbound US Prescribing Information

Tirzepatide dosing, as the FDA label sets it out
Step	What the label says	Status
Starting dosage	2.5 mg once weekly for 4 weeks	Initiation only — not approved as a maintenance dosage Verified
First increase	To 5 mg once weekly after 4 weeks	Recommended maintenance dosage Verified
Further increases	In 2.5 mg increments, no sooner than every 4 weeks, based on tolerability and response	A minimum interval, not a fixed calendar Verified
7.5 mg and 12.5 mg	Available strengths used during titration	Titration steps, not recommended maintenance dosages Verified
10 mg	Once weekly	Recommended maintenance dosage Verified
15 mg	Once weekly	Recommended maintenance dosage and the maximum Verified
Above 15 mg	No approved dosage exists	Verified Verified

Escalation is driven by tolerability and response, not by a calendar. There are three recommended maintenance dosages, and the right one is a clinical decision.

Why 'cheapest' needs a definition attached

Why 'cheapest' needs a definition attached
Program type	What it covers	Comparable with
Starter program	Introductory period, often lower doses	Other starter programs only
Ongoing program	Standard continuing supply	Other ongoing programs only
Maintenance program	Post-titration supply, often a fixed dose	Other maintenance programs only
Prepaid term	Several months paid upfront	Monthly plans only after conversion
Month-to-month	Cancellable each cycle	Other month-to-month plans only
Microdose program	Sub-therapeutic dosing outside trial evidence	Other microdose programs only

Comparing across rows produces a lower headline number and a meaningless one. We never do it, and neither should a provider quoting you a price.

Frequently asked questions

Why was my Zepbound prior authorisation denied?

The four common reasons are missing documentation, step therapy, an employer plan that excludes weight-loss drugs, and Medicare or Medicaid enrolment. Only the first two are usually resolvable.

Can I appeal a formulary exclusion?

Rarely successfully. An excluded weight-loss benefit is an employer purchasing decision rather than a clinical judgement, so clinical documentation does not address it.

Is there another indication that might be covered?

Tirzepatide carries an approved indication for moderate-to-severe obstructive sleep apnoea in adults with obesity, and many plans cover sleep apnoea therapy while excluding obesity drugs.
