The landscape of weight loss medication coverage is complex and constantly evolving. This article aims to provide a detailed overview of prior authorization requirements for weight loss medications, particularly GLP-1 receptor agonists, considering both general practices and specific changes in coverage policies.
Understanding Prior Authorization for Weight Loss Medications
Prior authorization is a process where your insurance company reviews and approves a prescription drug before it will be covered. This is a common requirement for many medications, including GLP-1 receptor agonists prescribed for weight management or the treatment of obesity. These medications, such as semaglutide (Wegovy, Ozempic, Rybelsus), liraglutide (Saxenda, Victoza), and tirzepatide (Zepbound, Mounjaro), have become increasingly popular due to their effectiveness in aiding weight loss, managing type 2 diabetes, and addressing related health conditions.
Why Prior Authorization Matters
While GLP-1 medications are approved for specific conditions, insurance coverage is contingent on the drug's labeled indication and your plan's formulary. Some health plans cover these medications for type 2 diabetes (Ozempic, Trulicity, Rybelsus, Victoza) but not for the treatment of obesity (Wegovy, Saxenda, Zepbound, Mounjaro). This discrepancy highlights the importance of understanding prior authorization requirements.
Strategies for Successful Prior Authorization
Getting a prior authorization request approved quickly often comes down to preparation. Most insurance companies set strict medical necessity criteria for GLP-1 weight loss medications. A strong prior authorization submission should include:
- The completed insurer-specific paperwork.
- A detailed letter of medical necessity explaining why the prescribed GLP-1 medication is the most appropriate choice (whether for an FDA-approved indication or a well-supported off-label use).
- Recent chart notes with body mass index, weight history, and relevant lab results such as A1C and cholesterol.
Common Hurdles and How to Overcome Them
Even with complete documentation, several hurdles can delay or prevent approval for GLP-1 weight loss medications.

- Exclusion of Obesity Drugs: Some insurance plans, including certain Medicare Part D and Medicaid programs, exclude coverage for obesity drugs altogether, making it necessary to ask about plan exceptions or explore patient assistance programs from manufacturers.
- Step Therapy Requirements: Others impose step therapy requirements, meaning you must try another drug first unless your provider can justify an exception for medical reasons.
- Off-Label Prescribing: Off-label prescribing (such as using Ozempic or Trulicity for weight loss without type 2 diabetes) can also be more difficult to approve, requiring a strong clinical rationale.
Navigating the Prior Authorization Process
Prior authorization processing times vary, but most insurers respond within 5-10 business days. For renewals, expect to submit updated weight measurements and health condition status to show continued benefit. Even with approval, GLP-1 drugs can come with high out-of-pocket costs.
The Role of Your Healthcare Provider
Your healthcare provider's role is essential in the prior authorization process. Be clear about your medical history, weight management goals, and any challenges you've had with previous medications or lifestyle interventions.
Appealing a Denial
If your doctor prescribed medication, but your insurer denied coverage, you have the right to appeal your health plan’s denial of benefits for covered services that you and your health care provider believe are medically necessary. There are two kinds of appeals - internal appeal and external review. You can learn how to file the appeals.
State-Specific Changes: North Carolina Medicaid
It's crucial to be aware of state-specific changes in coverage policies. For example, North Carolina Medicaid has announced changes to its coverage of GLP-1s for the treatment of obesity.
Effective Oct. 1, 2025, NC Medicaid coverage for GLP-1s for the treatment of obesity, which is an optional benefit for Medicaid programs, will be discontinued due to shortfalls in state funding.
GLP-1s will continue to be covered for the indications of diabetes, reduction in cardiovascular death, heart attack and stroke in obese adults with cardiovascular disease, noncirrhotic metabolic dysfunction-associated steatohepatitis (MASH) and severe obstructive sleep apnea (OSA).

Specific Changes:
- Wegovy, Zepbound, and Saxenda will be removed from the Preferred Drug List (PDL) as an off-cycle change, effective Oct. 1, 2025.
- Saxenda will no longer be covered for any indication.
- The Non-Incretin Mimetics class of drugs for treatment of obesity will continue to be managed through the PDL. Drugs in the Preferred status on the PDL include: diethylpropion, phendimetrazine and phentermine. These products do not require prior approval.
- Coverage of Wegovy and Zepbound will be managed through prior authorization, using clinical criteria established by the State for specific FDA-approved indications.
Continued Coverage for Other Indications:
- Wegovy: To reduce the risk of cardiovascular death, heart attack and stroke in adults with cardiovascular disease who are obese and for the treatment of noncirrhotic metabolic dysfunction-associated steatohepatitis (MASH), formerly known as nonalcoholic steatohepatitis (NASH), with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis) in adults.
- Zepbound: To treat moderate to severe obstructive sleep apnea (OSA) in adults with obesity.
Prior Authorization Requirements in North Carolina:
Providers will need to obtain a new prior authorization for beneficiaries receiving Wegovy and Zepbound, effective Oct. 1, 2025. Current prior authorizations will no longer be valid after Sept. 30, 2025. Prior authorization requests can be submitted beginning Oct. 1, 2025. There will be no changes to coverage for GLP-1 medications for the treatment of diabetes. Additionally, Weight Management (Non-Incretin Mimetics) will still be covered as listed on the PDL.
TRICARE Coverage for Weight Loss Medications
If you are a TRICARE beneficiary, understanding your plan's coverage for weight loss medications is essential. The Defense Health Agency is implementing regulatory controls on weight loss medication coverage, effective Aug. 31, 2025.
Key Points for TRICARE Beneficiaries:
- If you have TRICARE Prime or TRICARE Select, these medications are still covered in certain circumstances.
- If you have an approved prior authorization for weight loss drugs, it’s no longer valid.
- If your weight loss drug isn’t covered, you should speak with your provider about other options.
- TRICARE only covers weight loss medications for certain beneficiary groups.
- TRICARE covers Trulicity, Ozempic, Mounjaro, and Victoza to treat type 2 diabetes.
- GLP-1s for the treatment of diabetes continue to be covered for all patients with a diagnosis of diabetes when medically necessary and when prior authorization requirements are met.
- Use the TRICARE Formulary Search Tool to check costs and coverage requirements.
The Broader Context: Coverage Trends and Considerations
- Employer-Sponsored Health Plans: Some employers choose to exclude GLP-1 drugs from employer-sponsored health plans.
- Insurer Discretion: It is up to each insurer and its chief medical officer to decide if these medications will be covered.
- Cost Considerations: Some injectable drugs intended for weight management can cost $1,300 or more for a month’s supply without insurance.
The Importance of Healthy Habits
Forming healthy habits is crucial to maintaining a healthy weight. TRICARE covers weight loss medication drugs (including GLP-1s) when you meet certain criteria, based on diagnosis, medical necessity, and your TRICARE plan.
Seeking Expert Support
Prior authorization for GLP-1 weight loss medications can be frustrating, but working with a team that knows the process inside and out can save you time and reduce stress. Experts can help patients navigate coverage rules, meet insurer criteria, and submit complete documentation - including strong letters of medical necessity - to maximize the chances of fast approval.
