The list price of Mounjaro in the US is about $1,079.77 per month, making it a costly option for managing type 2 diabetes. Insurance may lower the cost, but many patients need prior authorization (PA) to get coverage. Unfortunately, this process is often complex and frustrating.
A 2021 survey on prior authorization highlighted these challenges. It showed that PA causes heavy administrative work, uses up resources, and can harm patient care. Even more concerning, 50% reported cases where patients experienced serious health issues due to delays caused by PA.
This article will guide you through the process of how to get prior authorization for Mounjaro, offer practical tips, and help you avoid delays so you can access your treatment sooner.
What is a Prior Authorization for Insurance?
Prior authorization (PA) is essentially your insurance company’s way of ensuring that the prescribed medication is medically necessary. For high-cost treatments like Mounjaro, here’s why they’re used:
- Cost Control: Insurance companies use PAs to manage healthcare expenses by ensuring that more expensive treatments are only approved when necessary. They aim to prevent unnecessary spending on costly medications or procedures when cheaper, equally effective alternatives exist.
- Ensuring Appropriate Use: PAs verify that a treatment or medication is suitable for the patient’s condition based on medical guidelines. This helps reduce overuse, misuse, or off-label use of certain drugs or treatments.
- Promoting Step Therapy: In many cases, insurance providers require patients to try less expensive or generic medications first (known as step therapy). If these options fail, the PA process allows approval of more advanced or costly treatments.
- Preventing Fraud and Abuse: PAs add an additional layer of oversight to prevent the misuse of expensive treatments or medications and reduce the risk of fraudulent claims.
How to Get Prior Authorization for Mounjaro

Generally, the process requires collaboration between your prescribing physician, you, and your insurance provider. Here’s a step-by-step guide:
Step 1: Compile the Necessary Documentation
Each insurance company typically has its own prior authorization form that needs to be completed and submitted. Your healthcare provider’s office is typically responsible for obtaining and filling out this form. Supporting documents that detail your medical need for Mounjaro are submitted alongside it.
The prior authorization requirements for Mounjaro may include the following:
- A confirmed diagnosis of type 2 diabetes.
- Evidence that metformin was not effective in managing your condition.
- Proof of insufficient response or contraindication to at least one of the following oral antidiabetic medications:
-
- Sulfonylureas
- Thiazolidinedione
- DPP-4 inhibitors
- SGLT-2 inhibitors
- Combination of the above therapies
- Clear clinical justification for prescribing Mounjaro.
- Dates and durations of past treatments.
- Supporting lab results like recent A1C levels, other comorbidities, and clinical notes that confirm the diagnosis.
When discussing with your doctor, start by sharing your treatment history. Explain which medications you’ve tried, how effective they were, and if you experienced any side effects.
Step 2: Submit the Prior Authorization Request
Once you have the necessary documentation, your healthcare provider’s office will submit the prior authorization request to your insurance company. This process is often done electronically, but some providers may use fax or mail.
For a smoother submission process, be sure to:
-
- Follow up and confirm with your insurance company that the request was received.
- Ensure no forms or required documents are missing.
- Be aware of your insurer’s response timeframe, typically 7-14 days.
Can A Prior Authorization Be Denied?
If your initial request is denied, don’t give up. About 6% of prior authorization requests are denied. Of those denials, only 11% are appealed, even though 82% of appeals are reversed. This happens because many patients and doctors don’t realize they can appeal.
Here’s what you need to do:
1. Understand the Denial
You are responsible for starting the appeal process by contacting your insurance company. Find out why your claim was denied and ask for a detailed written explanation. Denials for Mounjaro are usually due to one of these reasons:
Not Medically Necessary
This happens when the insurance company believes Mounjaro isn’t essential for your health. They may think it’s unnecessary for your condition, doesn’t follow standard treatment guidelines, or isn’t proven effective for your diagnosis.
This often occurs if:
- Your doctor didn’t explain why the treatment is critical.
- The insurance company’s policies differ from your doctor’s judgment.
- The wrong billing or diagnostic codes were used. Examples of ICD-10-CM diagnosis codes are:
-
- E11.65 (Type 2 diabetes with hyperglycemia)
- E11.8 (Type 2 diabetes with unspecified complications)
- E11.9 (Type 2 diabetes without complications)
Verify the correct codes were submitted. Work with your doctor to provide a letter explaining why Mounjaro is medically necessary, based on your diagnosis and medical history. Supporting documents, like test results or guidelines from medical organizations, can help.
Experimental Procedure
The insurance company may consider the treatment unproven or not widely accepted as effective. This can include new therapies, off-label medication use, or treatments lacking sufficient scientific evidence.
While this often applies to cutting-edge treatments or those not explicitly approved by regulatory agencies like the FDA, it is unlikely that Mounjaro would be categorized as “experimental” for diabetes since it is already FDA-approved for type 2 diabetes.
However, if Mounjaro is prescribed for a condition other than type 2 diabetes (e.g., weight loss without diabetes), insurance may classify it as experimental because the FDA has not approved it for that specific use. In such cases, coverage might be denied unless further evidence or justification is provided.
Your doctor can help by providing a letter explaining why the treatment is standard practice or supported by clinical evidence, including references to studies, guidelines, or other authoritative sources to demonstrate its effectiveness.
2. Write an Appeal Letter

Draft an appeal letter and include these details:
-
- your name and insurance policy number
- the authorization or claim number provided by your insurance company
- the date you initially requested prior authorization and the planned date for the service
- the reason for the denial given by your insurance company
- a request for the insurance company to review the prior authorization again
- your clinician’s explanation for the appeal, including references to studies or documents showing why the procedure is necessary for your condition
- any documents from your insurance plan showing the service is covered, along with your medical records proving you meet the criteria
- a closing statement from your clinician urging the insurance company to approve the prior authorization because it is essential for your care
- your clinician’s signature, the date, and their contact number
You may also include your perspective on how the treatment impacts your health and quality of life. If the denial is due to incorrect billing codes, your doctor’s office or billing department will correct and resubmit them. Many doctors’ offices will handle the technical aspects of the appeal, especially for complex medical justifications.
3. Submit Your Appeal
Submit your appeal within the specified time limit, which typically ranges from 30 to 60 days from the date of denial. You can find this information in your denial letter or insurance policy, so be sure to act quickly.
4. Track the Progress of Your Appeal
Most insurance companies that follow CMS (Centers for Medicare & Medicaid Services) rules must respond to your prior authorization appeal within 30 days. This means they have to decide whether to approve or deny the treatment before it happens.
5. Apply for a Second-Level Appeal (if needed)
If your first appeal is denied, you still have options. Most insurance companies allow multiple levels of appeal. The denial letter will usually include instructions on how to proceed with the next step.
If your insurance company denies your appeal at all internal levels, you may qualify for an external review. In an external review, an independent third-party organization evaluates your case. They will either:
- Agree with the insurer’s denial, or
- Decide in your favor, requiring the insurer to cover the treatment. In this case, the insurance company is legally required to follow the reviewer’s decision.
If you believe the denial is unjustified, you can file a complaint with your state’s Department of Insurance or a regulatory agency. In some cases, legal action may be an option, though it should typically be a last resort.
You need to remain persistent, gather strong evidence, and follow each step in the appeals process to maximize your chances of overturning the denial.
Explore Financial Assistance Options
While waiting for approval or during an appeal, consider financial assistance programs to help offset costs. Eli Lilly, the manufacturer of Mounjaro, offers a savings card and other patient support options. Additionally, there are other resources that you might want to consider, including:
-
- Explore Discount Pharmacies or Coupons: Use prescription discount programs like GoodRx, SingleCare, or Blink Health to check for lower prices at local or online pharmacies.
-
- Buy From Canadian Pharmacies: Many Americans save on medications by purchasing from Canadian pharmacies, which often offer lower prices compared to US pharmacies. At Pharma Giant, an online platform partnering with licensed Canadian pharmacies, you can find Mounjaro starting at $158.99. They also provide Mounjaro coupons to help you save even more.
-
- Apply for Financial Assistance: Some nonprofit organizations and foundations, like the PAN Foundation or NeedyMeds, offer financial assistance for specific medications.
Summary
Getting prior authorization for Mounjaro can feel challenging, but it’s doable with the right steps. Talk to your doctor, gather the necessary paperwork, and stay proactive. If you face issues, don’t give up because appeals and financial assistance programs can help. With persistence, you can get the treatment you need to support your health.
