For some people, managing diabetes involves daily insulin injections, including long-acting options such as Tresiba (insulin degludec). Tresiba is a once-daily, long-acting insulin used to help control blood sugar levels in people with Type 1 or Type 2 diabetes. It is approved for adults and children ages 1 and older. Healthcare providers may prescribe it alongside short-acting insulin medication. However, blood sugar control with Tresiba can become a high financial burden without insurance or discounts.
How much does Tresiba cost?
The cost of Tresiba depends on the dosage form. Tresiba is available as a vial or a Flextouch pen. The average retail price of Tresiba is $422 for one 10 mL vial of 100 units/mL insulin. Tresiba Flextouch costs $709 for a five-pack of 3 mL pens of 100 units/mL insulin. Tresiba Flextouch is also available as a 200 units/mL pen. Your actual cost will depend on the form, dose, pharmacy, and whether you use insurance or prescription discounts.
Does insurance cover Tresiba?
According to Novo Nordisk, Tresiba is covered by most major health insurance plans, including Medicare and Medicaid. Some commercial plans, including some Optum Rx 2026 plans, cover Tresiba vials and Tresiba Flextouch pens as Tier 1 medications, even though they are brand-name medications. Tier 1 medications typically have the lowest out-of-pocket costs.
In some 2026 Kaiser Permanente plans, Tresiba is covered as a Tier 2 medication that requires prior authorization. This means that the insurance company must approve coverage before they cover Tresiba. And even if the insurance plan provides coverage, you may pay more for Tresiba compared to Tier 1 medications.
Novo Nordisk says most Medicare plans cover Tresiba. Under Medicare Part D, insulin prescriptions are capped at $35 or less per month.
Medicaid plans usually cover Tresiba vials and Tresiba Flextouch pens. Coverage can sometimes come at no cost. California’s Medi-Cal Rx formulary includes both forms. The Aetna Better Health Premier Plan of Illinois, a Medicare-Medicaid plan, covers Tresiba with a $0 copay per prescription.

If you don’t have coverage for Tresiba or your plan doesn’t fully cover it, consider the following options to get it more affordably.

Medicaid coverage varies by state, but most state Medicaid programs include Tresiba on their formularies, often with low or no out-of-pocket costs for eligible patients. Some states may also offer State Pharmaceutical Assistance Programs (SPAPs) that provide additional support for people with limited income.
To find out how much you’ll pay under your specific plan, contact your Medicare Part D provider or your state’s Medicaid office for coverage details.
