What Is Prior Authorization?
Prior authorization (PA) is a pre-approval process that your insurance company requires before they'll pay for certain medications. When your prescriber writes you a Zepbound prescription, they (or their staff) must submit it to your insurance along with clinical documentation. The insurance company reviews this documentation to verify that the medication is medically necessary for your specific situation. Only after they approve it in writing can your pharmacy fill the prescription with insurance coverage.
If PA is not obtained before filling the prescription, or if your PA is denied, you have two options: pay the full out-of-pocket cost (typically $1,200-$1,500 per month for Zepbound) or work with your prescriber to appeal the denial.
Prior authorization is frustrating and time-consuming, but it's standard practice for expensive medications. Understanding the process helps you navigate it efficiently.
Why Do Insurers Require Prior Authorization for Zepbound?
Zepbound is expensive. Tirzepatide costs roughly $1,200-$1,500 per month at full retail price (approximately $15,000-$18,000 per year). For health insurance companies covering thousands of patients, this expense adds up quickly. Insurers use prior authorization to control costs by ensuring the medication is prescribed only when medically justified according to their specific criteria.
Most insurers have adopted PA criteria based on FDA approval guidelines: Zepbound (tirzepatide) is approved for weight management in patients with BMI ≥27 kg/m² with at least one weight-related condition (type 2 diabetes, hypertension, coronary artery disease, sleep apnea, etc.) OR BMI ≥30 regardless of comorbid conditions.
Additionally, many insurers add their own requirements beyond FDA approval: documented trials of lifestyle modification attempts, previous failure of other weight loss medications, or requirement to document specific weight-related health problems. These additional criteria vary by insurance plan.
The Prior Authorization Process: Step by Step
Step 1: Your Prescriber Writes the Prescription
Your doctor writes a Zepbound prescription and specifies the dose (typically 0.5mg starting dose, or higher if escalating from a previous dose). They also need to document your medical reason for the prescription in your medical record—this becomes critical for PA.
Step 2: Your Prescriber's Office Submits PA Request
Your prescriber's office submits a PA request to your insurance. This typically happens electronically through the insurance company's PA portal or by fax. The submission includes:
- Patient demographics (name, date of birth, member ID)
- Current height and weight (used to calculate BMI)
- List of current medications
- List of current medical diagnoses (diabetes, hypertension, sleep apnea, etc.)
- Clinical notes from recent office visit documenting the weight-related condition(s)
- Documentation of any previous weight loss interventions or trials of other medications
- Prescriber's clinical justification for why Zepbound is medically appropriate
- Proposed Zepbound dose and start date
Step 3: Insurance Company Reviews and Decides
The insurance company's medical review department (usually including physician reviewers and pharmacists) evaluates your PA request against their coverage criteria. This typically takes 2-5 business days. They determine whether you meet their requirements.
Step 4: Approval or Denial Notification
Your prescriber's office receives notification of approval or denial. They should notify you immediately. If approved, you can fill your prescription at the pharmacy—insurance coverage is confirmed. If denied, you can appeal or pay out-of-pocket.
Timeline: How Long Prior Authorization Takes
| Scenario | Typical Turnaround | Notes |
|---|---|---|
| Complete documentation, straightforward case | 2-5 business days | Most common scenario |
| Incomplete documentation, request for more info | 5-15 business days | Depends on how quickly your doctor responds with additional info |
| Expedited PA (medical urgency) | 24 hours | Requires documented medical justification for urgency |
| Initial denial + standard appeal | 5-15 business days from appeal submission | Your doctor resubmits with additional clinical information |
| Initial denial + expedited peer review | 1-3 business days | Doctor speaks directly with insurance medical director |
Key takeaway: Start the PA process as soon as you and your doctor decide to pursue Zepbound. Don't wait until your injection date. Most approvals take 2-5 days with complete documentation, so starting early prevents delays.
What Documentation Does Your Prescriber Need?
Complete documentation dramatically increases your chances of PA approval. Ensure your prescriber has included all of the following:
Patient Information
- Full name, date of birth, member ID
- Current height and weight (used to calculate BMI)
- Current age and sex
Medical and Medication History
- Complete list of current medications (including over-the-counter and supplements)
- List of current medical diagnoses (especially weight-related conditions: diabetes, hypertension, sleep apnea, heart disease, osteoarthritis, fatty liver disease, etc.)
- Previous attempts at weight loss (diet programs, exercise regimens, previous medications tried and reason for discontinuation)
- Any contraindications that have been ruled out (personal/family history of thyroid cancer, pancreatitis, diabetes complications, etc.)
Clinical Documentation
- Recent office visit notes (preferably within 1-2 months) confirming weight-related condition(s)
- Most recent lab results if applicable (HbA1c for diabetes, metabolic panel for other conditions)
- Prescriber's clinical statement: "Tirzepatide is medically appropriate for [patient name] given their BMI of [X] and documented [weight-related condition]. Prior attempts at non-pharmacologic weight loss have been undertaken/insufficient, and pharmacologic intervention is now clinically justified."
Before Your PA Appointment
- Call your prescriber's office 1-2 days before your PA submission and confirm they have your current height/weight
- Prepare a list of weight-related health conditions you have (diabetes, high blood pressure, sleep apnea, etc.)
- Ask if your insurance requires specific documentation beyond what your doctor typically submits
- Get your insurance member ID and confirm the PA portal your insurer uses
Common Reasons for Zepbound PA Denial
BMI Doesn't Meet Plan Criteria
Most common denial reason. Your insurance requires BMI ≥27 with documented comorbidities OR BMI ≥30. If your BMI is 26.5 or 28 with no documented weight-related conditions, you'll likely be denied. Ensure your recent office visit included documented diagnosis of weight-related conditions (especially if you have diabetes, hypertension, or sleep apnea).
Insufficient Medical Documentation
Your prescriber's submission lacks clinical detail. Solution: have your doctor resubmit with recent office visit notes documenting your weight-related condition(s), current medications, and weight loss history. This is the most fixable denial reason.
No Documentation of Lifestyle Modification Attempts
Some insurers require evidence that you've tried diet, exercise, or behavioral interventions before approving Zepbound. If your notes don't mention this, ask your prescriber to document: "Patient has attempted calorie restriction and exercise for [timeframe] with insufficient results" or similar. This single sentence often resolves denials on appeal.
Patient Is Pregnant or Breastfeeding
Zepbound is contraindicated in pregnancy and breastfeeding. If your insurance has this information in their system (possibly from previous pharmacy records), they may automatically deny. If you're not pregnant/breastfeeding, ensure your record is updated.
Insurance Plan Limitation
Some insurance plans don't cover weight management medications at all or cover them only under limited circumstances. Check your plan's pharmacy formulary or call your insurance to understand their policy. If your plan genuinely doesn't cover Zepbound, you may need to pay out-of-pocket or explore other options.
Previous Failure or Discontinuation of This Medication Class
If you previously used semaglutide (Ozempic/Wegovy) or another GLP-1 and stopped it, your insurance may question why you're requesting tirzepatide. Solution: have your doctor document why you're switching ("Patient discontinued semaglutide due to unacceptable side effects; tirzepatide offers [specific advantage]") or why this is a new attempt ("Patient was not previously on GLP-1 therapy").
How to Appeal a Zepbound PA Denial
Standard Appeal (5-15 Business Days)
If your initial PA is denied, you have the right to appeal. Your prescriber can submit an appeal with additional or reframed documentation. Here's the process:
- Contact your prescriber's office immediately and request they submit an appeal
- Ask specifically why the PA was denied ("Did they say BMI was too low? Say we didn't document enough weight loss attempts?")
- Work with your doctor to address the specific denial reason in the appeal submission
- Your doctor resubmits the PA request with additional documentation or clinical justification addressing the denial reason
- Insurance reviews the appeal and notifies you of the result in 5-15 business days
Appeal strategy: If your initial denial was for BMI criteria, ensure your appeal emphasizes documented weight-related conditions (diabetes, high blood pressure, etc.). If the denial was for insufficient documentation, provide comprehensive office visit notes. Appeals often succeed because you're now providing the specific information the insurance initially wanted.
Expedited Peer-to-Peer Review (1-3 Business Days)
If a standard appeal is denied or you need faster resolution, request an expedited peer-to-peer review. This involves your prescriber speaking directly with an insurance company medical director (rather than just written documentation review). These conversations are often more successful because your doctor can explain clinical reasoning directly.
To request peer review: contact your prescriber's office and ask them to request "peer-to-peer review" or "physician-to-physician review" from the insurance company. Your doctor contacts the insurance medical director directly. Most insurers approve within 24-48 hours after peer review.
What to Do While Waiting for PA Decision
Timeline Expectations
- Day 1: Prescription submitted to insurance
- Day 3-5: Decision typically made (can be as fast as day 1-2 for straightforward approvals)
- Day 5: If you haven't heard back, have your prescriber's office call the insurance PA line to check status
- Day 7+: If still pending, insurance may be requesting additional information from your prescriber
Communication Strategy
- Request that your prescriber's office calls you as soon as they hear PA approval or denial (don't wait for mail notification)
- Exchange phone numbers with the PA coordinator at your prescriber's office so you can follow up if needed
- Ask if your prescriber's office uses an electronic PA portal where you can track status yourself
- On day 5, if you haven't heard anything, call your prescriber's office to confirm the PA was submitted and ask for status
Once PA Is Approved
PA approvals typically include an authorization number and approval duration (usually valid for 1 year from approval date or specified end date). The approval is communicated to your prescriber and pharmacy electronically.
Next steps after approval:
- Call your pharmacy to confirm they received the PA authorization and can fill your prescription
- Ask the pharmacy for your out-of-pocket cost (copay or coinsurance) at that pharmacy
- Confirm the pharmacy has your prescription in stock (Zepbound pens can be temporarily out of stock)
- Schedule pickup or delivery according to your injection schedule (typically weekly for ongoing treatment)
If Your PA Is Denied and You Can't Appeal
If your PA is denied and appeals are unsuccessful, you have several options:
Pay Out-of-Pocket
Zepbound costs $1,200-$1,500 per month at standard pharmacy prices. However, you may reduce this through:
- GoodRx discount coupons: Often reduce cost to $800-$1,200 per month (search GoodRx.com for local pharmacy prices)
- Manufacturer copay cards: Eli Lilly offers copay assistance even when insurance denies—can reduce cost to $0-250 per month
- Walmart/Target/local pharmacies: Prices vary; call several to compare
- Telehealth providers: Some online prescribers offer bundled pricing including the injection itself
Manufacturer Support Programs
Eli Lilly (Zepbound manufacturer) offers several support programs:
- Lilly Insulin Value Program: Copay assistance up to $35 per month for eligible patients
- Lilly Connect Patient Assistance Program: Free or low-cost medication for uninsured/underinsured patients; must meet income requirements
- Zepbound Savings & Support: Manufacturer website has savings information and patient assistance details
Call Zepbound customer service at 1-855-469-2353 or visit the Zepbound website to explore these programs.
Insurance Appeal or Complaint
If you believe the PA denial was unfair or your insurance applied incorrect criteria:
- Request written explanation of denial (your insurance must provide this on request)
- File a formal appeal with your insurance company's appeals department (different from PA appeal process)
- File a complaint with your state's insurance commissioner if you believe your insurer violated regulations
Try a Different Weight Loss Medication
If your insurance denies Zepbound specifically but covers other weight loss medications, ask your doctor about alternatives:
- Semaglutide (Ozempic/Wegovy): GLP-1 alone, sometimes covered when tirzepatide isn't
- Naltrexone/Bupropion (Contrave): Often cheaper, different mechanism, some insurers cover this preferentially
- Orlistat (Xenical): OTC available, minimal insurance restriction, but less effective than GLP-1/GIP
- Other options: Discuss with your doctor what your insurance actually covers

Frequently Asked Questions
Prior authorization (PA) is a requirement from your insurance company that your prescriber submit clinical documentation BEFORE they approve payment for a medication. Insurers use PA to verify that the medication is medically necessary and that you meet specific criteria. Without PA approval, your insurance may deny the claim or refuse to pay, leaving you responsible for the full cost.
Zepbound is expensive (roughly $1,300-$1,500 per month retail). Insurers use PA to control costs by ensuring it's prescribed only when medically justified. PA criteria typically include: BMI ≥27 with at least one weight-related condition (diabetes, hypertension, sleep apnea, heart disease) OR BMI ≥30 regardless of conditions. Some insurers also require documented failure of other weight loss attempts.
Standard PA decisions typically take 2-5 business days from the time your prescriber submits complete documentation. However, if documentation is incomplete or the insurer requests additional information, it can take 1-2 weeks. Emergency or expedited PA (for patients already on tirzepatide through other channels) can be approved within 24 hours. Plan ahead rather than waiting until you need your first injection.
Your prescriber must submit: your current height and weight (BMI calculation), current medications and medical conditions, documentation of weight-related conditions (diabetes, hypertension, etc.) from clinic notes, evidence of previous weight loss attempts if required by the plan, a statement that non-pharmacologic approaches have been tried or that medication is medically appropriate, and the prescribed tirzepatide dose. Having recent office visit notes helps.
Common denial reasons: BMI doesn't meet plan criteria (usually needs BMI ≥27 with comorbidities OR BMI ≥30), no documented weight-related conditions, insufficient documentation that non-medication weight loss attempts were tried, patient is pregnant or breastfeeding, insurance considers weight loss outside their covered benefit, or past claims show the patient previously failed/discontinued this medication class.
Yes. After denial, you have the right to appeal. Your prescriber can submit an appeal with additional clinical justification. Appeals typically require new documentation or reframing existing information to meet the plan's criteria. Standard appeal turnaround is 5-15 business days. If the standard appeal is denied, request an expedited peer-to-peer review between your doctor and the insurance medical director—often more successful.
While waiting: don't delay submission (submit immediately once you decide to pursue treatment), don't assume denial (most initial PA approvals take 2-5 days), have your prescriber's office follow up on day 5 if you haven't heard anything, stay in contact with your prescriber's office staff (they manage PA submissions), and have a plan for getting your prescription filled quickly once approved (call pharmacy before pickup to confirm insurance coverage).
Options: pay out-of-pocket for Zepbound ($1,200-$1,500 per month via GoodRx or directly from pharmacies), use manufacturer discount programs if you don't have insurance, try switching to a different insurer if you're between plans, request your prescriber try appealing on clinical grounds, explore whether your employer plan or state Medicaid program covers tirzepatide, or discuss alternative weight loss medications that your insurance does cover.
Eli Lilly (Zepbound manufacturer) offers copay cards that reduce patient out-of-pocket cost to as low as $25-75 per month if insurance covers any amount. If insurance denies coverage entirely, Lilly also offers patient assistance programs for uninsured/underinsured patients. Visit the Zepbound website or call 1-855-469-2353 to inquire. These programs can help bridge the gap during PA delays.
Possibly. Request expedited PA if: you're already on another tirzepatide product and switching to Zepbound (medical continuity argument), you're part of a clinical trial or transplant situation requiring urgency, or you have acute complications requiring urgent weight loss treatment. Standard expedited PA typically processes in 24 hours. Routine cases don't usually qualify for expedited review.
