Is Dupixent Covered by Insurance?

Dupixent (dupilumab) is a prescription medication used to treat a variety of chronic inflammatory conditions, such as atopic dermatitis, asthma, and chronic rhinosinusitis with nasal polyposis. As a biologic medication, Dupixent has shown significant efficacy in managing symptoms and improving the quality of life for patients. However, due to its high cost, many patients and their families are concerned about whether Dupixent is covered by insurance.

Coverage by Private Insurance

Most private health insurance plans cover Dupixent, but coverage specifics can vary widely depending on the insurer and the patient’s individual policy. Typically, for Dupixent to be covered, patients must meet certain criteria set by the insurance company, which often includes having a diagnosis for an approved condition and having tried and failed to respond to other treatments. Patients may need to obtain prior authorization, which involves the healthcare provider submitting documentation to the insurance company to justify the need for Dupixent.

Medicare and Medicaid Coverage

For those on government-sponsored health insurance programs like Medicare and Medicaid, Dupixent is generally covered, but again, coverage specifics can vary. Medicare Part D, which covers prescription drugs, often includes Dupixent, but patients may still encounter high copayments or coinsurance costs. Medicaid coverage for Dupixent can differ from state to state, as each state administers its own Medicaid program and sets its own coverage guidelines.

Patient Assistance Programs

Recognizing the financial burden that the cost of Dupixent can place on patients, the manufacturer, Regeneron Pharmaceuticals, offers patient assistance programs. These programs are designed to help uninsured and underinsured patients access Dupixent at reduced costs or even for free in some cases. Eligibility for these programs typically depends on the patient’s income level and insurance status.

Navigating Insurance Appeals

If an insurance company denies coverage for Dupixent, patients and healthcare providers have the option to file an appeal. This process involves submitting additional information and documentation to support the necessity of the medication. Success in these appeals often depends on demonstrating that Dupixent is essential for the patient’s health and that other treatments have been ineffective or are not suitable.


While Dupixent is a highly effective treatment for several chronic inflammatory conditions, its high cost can be a barrier for many patients. Fortunately, most private and public health insurance plans do cover Dupixent, although the extent of coverage and out-of-pocket costs can vary. Patients are encouraged to work closely with their healthcare providers and insurance companies to understand their coverage options and to explore patient assistance programs if needed. For those facing coverage denials, the appeals process provides a pathway to potentially gaining access to this vital medication.
