Mounjaro Formulary Denials, Explained

Key takeaways

  • If your Mounjaro prior authorization was denied due to the drug not being on your plan’s formulary, it means that your pharmacy benefit manager has chosen not to offer coverage of the medication.
  • Even if Mounjaro is not on your formulary, you may still be able to overturn GLP-1 coverage denials through an effective appeal. Depending on which state you live in, your doctor can also submit a Formulary Exception Request on your behalf.
  • For your appeal, it’s important to gather all relevant information you can find regarding your diabetes diagnosis or your risk of developing diabetes, your related medical conditions, and previous lifestyle modification attempts.

What is a formulary?

A formulary is a list of covered drugs under your health plan. Your plan’s formulary is determined by your insurance provider’s pharmacy benefit manager, or PBM for short. A PBM is a third party entity which is contracted by your insurance provider to handle medication coverage. The decisions about what to include on your formulary is usually guided by a pharmacy and therapeutics, or P&T, committee.

An insurance provider may choose to leave higher-cost medications such as Mounjaro off of a formulary because this is an effective way for your insurance company to control and lower its costs. Since Mounjaro does not have a generic alternative, most insurance providers will include lower cost medications as alternatives on their formulary, or as preferred step therapy medications. For more information on step therapy, check out our blog article on Step Therapy Denials.

Common preferred alternatives to Mounjaro on a formulary include:

Metformin
Rybelsus
Victoza
Byetta
Trulicity

“Not on Formulary” vs. “Plan Exclusion”

While PBMs do rely on the guidance of pharmacy and therapeutics committees to advise which drugs should be included (and in which order they’re covered), ultimately the PBM makes the final call on included drugs. If your coverage request was denied due to Mounjaro not being on your plan’s formulary, this means that your PBM has chosen not to include the medication on your formulary, and you may be able to have this decision overturned by having your provider submit a Formulary Exception Request, or by submitting an effectively written appeal.

Since Mounjaro is FDA approved for the treatment of Type 2 diabetes, it’s more likely that Mounjaro will be non-formulary as opposed to fully excluded. A plan exclusion means that your employer has specifically chosen not to include coverage of the medication or drug class in your plan. This type of appeal, while not impossible to win, can be quite challenging to overturn since the issue lies with the plan chosen by your employer. For more information on exclusion denials, see our blog post on Weight Loss Plan Exclusion Denials, Explained.

How to find out if Mounjaro coverage was denied for being non-formulary

To pin down your denial reason, the first place you should look is your official denial letter, which your insurance company will send to you via email or traditional mail. Below are examples of denial statements that may indicate your requested medication is not on your insurance formulary:

  • This request was denied because you did not meet the following requirements: The requested medication is not covered because it is not on the listing or formulary of approved drugs for your plan benefit. Please discuss alternative drug therapy with your doctor/plan.
  • Your request for coverage of Mounjaro has been determined as not medically necessary.  Per physician review, current plan approved criteria and current medical literature do not support the use of Mounjaro over the available formulary alternatives.

If you aren’t able to find your denial letter (or haven’t received it yet) you can also call your insurance provider directly to inquire the reason for the denial. While you’re at it, be sure to ask about your appeal options and your plan’s preferred method of submitting an appeal. Know that you have the legal right to appeal an insurance denial, and you can submit your appeal either on your own, or with the help of your provider.

Steps for writing an effective appeal

If you were denied medication coverage for any reason, we recommend appealing. If you're appealing your Mounjaro denial on your own, consider allowing Honest Care to help. We provide professionally crafted appeal letters at no cost, with only minimal edits needed for personalization. If you’d prefer a more hands-off approach, we also offer pricing options for fully customized services. Take the assessment here.

What is an appeal?

An appeal is a formal request to your health insurance company to reevaluate its decision to deny coverage for a medical therapy or service. When insurance first denies coverage for a GLP-1 medication, the denial decision is almost always made by a computer. In the appeal process, a real person has to review your coverage request and make a decision. You can send an appeal within six months of the denial notice. When insurance denies coverage, they are obligated to send you an explanation about why they denied coverage and instructions on how and where to send an appeal. Mail and fax are two common ways to submit an appeal. Visit healthcare.gov for general information on appeals.

Know your medical history

If Mounjaro is not included on your plan’s formulary, your PBM likely has a list of preferred medications (organized into tiers). Your best bet for having your denial overturned is to make a case for yourself on why these “preferred” medications will not work for you.

  • Have you already tried one or more? If you’ve already tried one or more preferred medications, be sure to note the details of each trial. List the dates and durations you took the medications, the effectiveness (or lack thereof) of each, your starting and ending weights, and any negative side effects you experienced while on treatment.
  • Are any of the medications contraindicated or expected to cause you physical or mental harm? In simple terms, this means that the risks of using the medication likely outweigh the potential treatment benefits. This may apply based on medical conditions, drug interactions, or medication side effects.
  • Are any of the medications expected to be ineffective? Restrictive formulary policies help insurance companies save money because the other diabetes medications are cheaper than Mounjaro and other GLP-1s, and these medications are cheaper because they are also less effective than GLP-1s. Within an appeal, clinical research demonstrating the inferiority of a required medication compared to the Mounjaro can be included. For example, you might cite research studies showing that metformin or even Ozempic is a less effective diabetes medication than Mounjaro within your appeal
  • Have you already demonstrated positive treatment on Mounjaro? If you already started taking Mounjaro you were denied coverage for and have experienced positive clinical results, this can help your case for overturning your denial by emphasizing continuation of treatment. If this is the case for you, you’ll want to share details on the clinical progress you have made while on treatment.

Highlight your previous efforts

Be sure to note any efforts you’ve made to improve your health (specifically your HbA1c), such as any specific diets or programs you’ve tried. It can be helpful to include receipts with your appeal letter if you’ve ever participated in a paid health management program or worked with a nutritionist. Since Mounjaro is intended to be used alongside a healthy diet and exercise regimen, be sure to also include any gym memberships or exercise programs you’ve tried.

Call out the cost

Since formulary decisions are first and foremost made with cost at the top of mind, it never hurts to call out potential future expenses if your condition goes untreated. The cost of treating diabetes-adjacent conditions such as heart disease, stroke, and Metabolic Syndrome can far outweigh the cost of covering your requested medication now.

Submit your appeal

Be sure to read your denial letter (or call your insurance company) to determine how you should submit your appeal. Some plans require appeals submitted through snail mail, and some allow for electronic submission. Your denial letter will also include where your letter needs to be sent. You should also include your Member ID and your claim number in the header of your appeal.

How does Honest Care help with insurance denials?

We help patients fight insurance coverage denials so they can get access to the medications and treatments they deserve. We currently specialize in insurance coverage denials for Ozempic, Mounjaro, Wegovy and Zepbound.

If you are denied coverage for Ozempic, Mounjaro, Wegovy or Zepbound, Honest Care can help fight your denial by submitting an ‘appeal’ to your insurance. An appeal is a formal request to your health insurance company to overturn their denial and grant coverage on your behalf. An appeal generally consists of a formal letter, addressed to your insurance, explaining why a medication should be covered on your behalf and why your insurance’s initial denial should be overturned.

You have the right to appeal to your insurance’s coverage denial. Honest Care simplifies the appeals process by writing an appeal letter and supporting documents on your behalf making your best arguments for medication coverage, following your completion of our proprietary GLP-1 denial assessment.

Should I appeal if my insurance denied coverage?

If your insurance denied coverage for Ozempic, Mounjaro, Wegovy or Zepbound, you have the legal right to ask your insurance to reconsider the coverage denial by sending an ‘appeal’.  Unfortunately coverage denials too often go unchallenged. A study from September 2023 found that 69% of people who were denied coverage by their insurance didn’t know they could appeal, and 85% of people never tried to appeal.

We believe it always makes sense to appeal. Here is why:

Appeals work: According to a study analyzing data from several U.S. states, patients who appealed directly to their insurance provider (an internal appeal) experienced a success rate between 39-59%.

Denials are often issued by mistake: A computer almost always makes the initial decision to deny medication coverage. This results in denials that don’t actually consider your personal health situation or denials made by mistake. In the case of Ozempic, Mounjaro, Wegovy and Zepbound, incorrectly entered information about your BMI, labs including A1c, your health conditions and diagnoses, your medication history and current medication use can all lead to an automatic denial. When you appeal, your information is reviewed by a real person.

Doctors review appeals, not computers: Having a doctor consider your unique circumstances makes submitting an appeal a powerful process for overturning denials getting covered.

You deserve the best care: You have the legal right to fight the treatment you need. As a part of the Affordable Care Act, all health insurance plans are required to allow their members to appeal their coverage decisions. This spans all insurance coverage - whether you are insured through your employer, purchased an insurance plan through your state marketplace, or are insured through a government program like Medicare or Medicaid.

What is an insurance appeal?

An insurance appeal is a formal request you make to your insurance company, asking them to reconsider a decision about your claim. This could be when they've denied your claim, not paid enough, or made a decision you disagree with. The appeal is your chance to argue your case, showing them why their decision should be different. It involves submitting a well-structured letter, along with any supporting evidence like medical records or repair estimates, to make your case stronger.

What is an insurance appeal letter?

An insurance appeal letter is your way of asking the insurance company to reevaluate a decision, such as a denied claim. It's essentially your argument in writing, explaining why you believe their decision should be different. This is a common document patients can use to advocate for themselves with their insurance to cover their medical costs even prior to being denied for a treatment.

This letter will include your policy details, specific decision you disagree with, and provide solid reasons and evidence (like weight loss efforts, past and present medications, labs, receipts etc) for your appeal. The letter should be clear, concise, and respectful, ending with a specific request for what you want your insurance to do.

You can submit an appeal letter directly to your insurance or through your health care provider as part of your insurance appeal process.

What is supporting insurance evidence?

Insurance supporting evidence is the documentation or information you provide to back up your claim or appeal with your insurance company. It's the proof that supports your case, like medical history, diet and exercise efforts, medication history, or relevant medical studies. This evidence is crucial because it shows the insurance company why they should approve your claim or reconsider a decision they've made.

We provide 3 types of supporting insurance evidence.

(1) Appeal Evidence - is the information you provide when you disagree with your insurer's decision about a claim or coverage. This could include detailed medical records, letters from your doctor explaining the necessity of a treatment, or information about how a treatment is standard for your condition. This evidence is crucial for challenging a denial or underpayment of a claim. Our role is to help you gather and present this evidence effectively, ensuring it clearly supports your need for the treatment or service claimed.

(2) Prior Authorization Evidence - is required when your health plan needs you to get approval before it covers certain medications or procedures. This evidence typically includes medical records, lab results, and a detailed rationale about why this specific medication or procedure is necessary for your condition. Our service involves assisting you in compiling comprehensive and relevant documentation to justify the medical necessity, aiming to secure approval from your insurance company for the required treatment.

(3) Step Therapy Exclusion Evidence - is used when you need to bypass the 'step therapy' protocol of your insurance plan. This protocol usually requires trying less expensive treatments before more costly ones are approved. Exclusion evidence might consist of medical records showing previous treatment attempts and failures, clinical data indicating why standard treatments are unsuitable or harmful for you, and detailed explanations about the necessity of the specific, often more expensive, treatment. We help you collect and organize this evidence to make a compelling case to your insurer that the standard step therapy process is not appropriate for your situation, thereby aiming for an exemption.

How can working with a regular doctor increase your chance of insurance coverage compared to telehealth?

Working with your regular doctor can increase your chance of insurance coverage in several ways, including:

  • When your insurance plan is making a decision on whether to cover your GLP-1 prescription, they will want to review your medical history and recent labs results. Your doctor already has this information within your patient chart, and if you don’t have recent labs, your doctor can order new labs during your appointment. Most online, telehealth-based GLP-1 clinics do not have access to your full medical history in your patient chart, which limits their ability to achieve insurance approval.
  • In the event your insurance plan initially denies coverage for your GLP-1, this decision can be appealed by your doctor by writing a “Letter of Medical Necessity” and sending it your insurance company. Writing an effective letter requires a doctor to have a real relationship with their patient. Online, telehealth-based GLP-1 clinics find it challenging to write effective "Letters of Medical Necessity" given their lack of personal relationships with patients.
  • Insurance plans are increasingly flagging and scrutinizing GLP-1 prescriptions written by online, telehealth-based GLP-1 clinics. Working with a regular doctor can help avoid this additional scrutiny.

Can the Honest Care Report be shared with telehealth doctors?

Yes - your Honest Care Report can be submitted to any doctor, including doctors working with online, telehealth-based GLP-1 clinics. Taking the Honest Care Assessment before engaging with a telehealth services presents several advantages, including helping you save money.

By using Honest Care before engaging with a telehealth company, you’ll find out how likely you are to get a GLP-1 prescription and will receive guidance on any recommended steps to take before your GLP-1 appointment. This can save you money by avoiding paying subscription fees until you’re fully prepared for your telehealth appointment.

Who is eligible for GLP-1s?

There are nearly 10 GLP-1 medications available in the United States. Currently three of those medications, Zepbound®, Wegovy® and Saxenda®, are FDA-indicated for weight-loss assistance. The FDA indicates that people with a BMI ≥ 30 kg/m2 OR people with a BMI ≥ 27 kg/m2 who have been diagnosed with at least 1 weight-related condition are eligible for GLP-1s.

All other GLP-1 medications, including Ozempic® and Mounjaro®, are currently FDA-indicated for people diagnosed with Type 2 diabetes.

I already know I’m eligible for GLP-1s based on FDA-guidelines. How can Honest Care help me with eligibility?

While FDA-guidelines are critical for understanding GLP-1 eligibility, there are a number of other factors to consider for determining GLP-1 eligibility.

Additional eligibility criteria that Honest Care takes into account include:

  • Weight-related conditions by importance in Prior Authorization (PA) - insurance plans often take certain conditions more seriously than others when determining GLP-1 eligibility.
  • Medication step therapy - many insurance plans only consider patients eligible for GLP-1 coverage only after trying lower-cost weight loss assistance medications first.
  • Ethnicity-based BMI guidelines for determining whether a patient is overweight by ethnicity.

What is Prior Authorization (PA)? Does Honest Care help with insurance?

Prior Authorization (PA) is a process run by insurance plans to determine how necessary a medication is. Most insurance plans require Prior Authorization (PA) before approving coverage for GLP-1s.

After your GLP-1 prescription is written, your insurance plan will notify your doctor if a PA is required and ask your doctor for additional documentation on why your medication is necessary.

If a PA is required, your insurance plan will ask your doctor to submit detailed information on your diet and exercise history, your past weight loss attempts, weight loss medications you previously tried, and any unique challenges that you face that make a GLP-1 medically necessary.

The Honest Care Report includes evidence requested by most insurance plans and can be submitted to your insurance during the PA process. During your appointment, your doctor can attach your Honest Care Report to your health record so it is submitted as supporting evidence to your insurance if Prior Authorization is required.
