Health Insurance Hurdles 101: Insulin + Diabetes Supplies


Editor’s Note: People who take insulin require consistently affordable and predictable sources of insulin at all times. If you or a loved one are struggling to afford or access insulin, click here.

Congratulations, you have health insurance! But your diabetes supplies and medications are still expensive and the specific brands your plan covers change year to year. What’s a person with diabetes to do? We know that just having insurance certainly doesn’t solve the cost headaches, and often presents a whole other set of issues to navigate. This resource is designed to help people WITH health insurance navigate some of the challenges that may arise while living with diabetes. Some of it is in your control, but a lot of it is out of your control, so here some suggestions for navigating a complex healthcare system with a chronic condition.

If you are having trouble obtaining insurance or supplies, please see our other resources for those specific scenarios:

This guide uses health insurance terminology that can be found in this glossary.

My insulin is not in my formulary.

Most insurance plans price their prescription drugs through a system called a formulary. These are most often placed into tiers—usually a four-level system that dictates your copay or coinsurance—by price of the drug. Due to the complexities of insulin pricing, your pharmacy plan will have a negotiated rate with one of the insulin manufacturers, and that is the drug that will be in your formulary at the covered rate. These negotiations happen every year, so even if your preferred insulin type—let’s say Novolog insulin made by Novo Nordisk—is covered one year, the next year it may switch to an insulin that is considered to be interchangeable—like Humalog insulin made by Eli Lilly—even though it is not interchangeable for everyone.

Here are some things you can do:

  1. Call your insurance provider to discuss what medications are on your formulary and the cost to continue using your usual insulin.
  2. Call your doctor to discuss switching to the covered insulin and what that would entail for your quality of care. In many cases, switching brands would be equivalent to buying Charmin vs. Cottonelle toilet paper: it is a different brand of the same product with the same effectiveness.
  3. If you find that your diabetes-related quality of life has diminished due to the change in insulin, first call your doctor to determine next steps for your health. Make a care plan you can stick with to keep yourself healthy. If the insulin is the issue, they can identify that and work with you to appeal your insurance.
  4. Appeal to your insurance. Warning: this is a process that takes time and patience. You will need a letter of medical necessity demonstrating that your quality of care is worse on the formulary insulin than on your previous insulin. You will need to work with your health insurance, pharmacy provider and physician in order to process all of the necessary information. This is a time to be resilient and advocate for yourself; you do not need to use a treatment plan that is not working simply because the insurance says so. Keep at it, and you may succeed.
  5. Speak with the people who choose your health insurance plan. If you are on an employer-based health insurance plan, you may want to have a conversation with your benefits manager (usually in HR or a business office) to request that your insulin be on the formulary list in the coming benefit year. If your employer does not know what you need, they cannot accommodate it, so, again, this is a time to advocate for yourself. If you are signing up for an Affordable Care Act plan (i.e. through, read all of the literature to verify that your medications are covered BEFORE you finalize the insurance purchase.
  6. If you cannot afford the insulin that works best for you, you are actually in a decent position! Because you have health insurance, you automatically qualify to use copay cards, which can bring your monthly copay down to as little as $0 per month.

Why are my insulin pump/continuous glucose monitor (CGM) supplies so expensive?

There are two components of health insurance coverage: medical coverage and pharmacy coverage. Pharmacy covers prescription medications. Medical covers physician visits, tests, hospitalizations and more, including a category called “durable medical equipment” (DME).

CGMs, insulin pumps and insulin pump supplies are considered DME, therefore they fall under the medical plan rather than the pharmacy plan (with the exception of the Freestyle Libre CGM that falls under pharmacy benefits and the Omnipod insulin pump that can be billed through either channel. Dexcom CGM supplies may also fall under pharmacy for some people).

Because they are billed through the medical channel, you must first meet your deductible and then pay your coinsurance on these supplies until you reach your out-of-pocket limit. This can be a prohibitively burdensome cost, particularly for those with high deductibles, but can remain prohibitive even once your deductible is hit.

What can you do?

  1. Plan ahead. Consider trade-offs you are willing or able to make. Speak with your doctor—you may only be able to afford either insulin pump or CGM supplies, and your doctor may be able to help you decide what is best for you.
  2. If you have a High Deductible Health Plan (HDHP), maximize your Health Savings Account (HSA). This is pre-tax money you set aside from your paycheck that is yours to use for healthcare expenses for the rest of your life. Since your HSA balance rolls over year-to-year, you can use this type of account to set aside pre-tax dollars as your savings for your portion of the healthcare expense. Ensure you are taking advantage of funds your employer provides to your HSA (not all do, but some do, and if you’re not sure it is worth asking).
  3. If you are able, choose a PPO plan rather than an HDHP plan. This allows less of a front-end cost to hit you all at once, provided the plan covers the brand of insulin pump or CGM you are trying to get. Which leads us to…

Ok, so I know that my pump and CGM are considered DME. The one I want STILL isn’t covered.

This is a more complicated one. Due to preferred provider negotiations between insurers and device manufacturers, the device that you have researched and decided is perfect for you is not covered by your plan. An example of this—Beyond Type 1 and JDRF have been advocating for United Healthcare to include other brands of insulin pumps in their plans after they announced a preferred provider relationship with Medtronic (more on that here).

If you are facing a device denial, here are some suggestions for a course of action:

  1. Be the CEO of your device prescription. Work with your physician, diabetes educator, local device sales representative and insurance company to understand what your options are and what the coverage is like so you can make an informed decision. You will need a prescription and a letter of medical necessity in order to get the device.
  2. If the device you want is not covered by your insurance plan and you still want it, you will face a denial. For a guide on how to appeal a denial, click here.
  3. It is best if you can provide clinical data to support your appeal. For instance, a demonstration of time in range or A1C that is improved with the treatment you want vs. the treatment your insurance will cover. Work with your doctor to build your case here.
  4. If you pay out of pocket as you navigate the bureaucracy, you run the risk of never being reimbursed, so make sure you have spoken with all of your providers (the companies and physicians) before putting down your own money.

The world of health insurance is its own complex web of policies and bureaucratic nonsense. It takes persistence and perseverance to advocate for yourself and what you know is right. You should always be the expert on what your plan covers and what you need to take care of your own health, and it takes that CEO mentality to negotiate with your providers to get everything you need. You already manage your health on a daily basis; you can do this, too.
