What Your Prescriptions Cost
How much does Enbrel cost with Medicare in 2026?
Last reviewed: · Big Sioux Benefits Data Desk
Enbrel has a Medicare-negotiated price of $2,355 for a 30-day supply as of January 1, 2026, down from a list price of $7,106, a 67% reduction (CMS, Negotiated Prices for Initial Price Applicability Year 2026). About 48,000 Medicare beneficiaries used it in 2023, a comparatively small group, but they accounted for $3.0 billion in Part D gross covered drug costs because the drug is so expensive per fill.
The qualifier: for a drug at this price, the negotiated price is not really what determines your year. The $2,100 out-of-pocket cap is. A single monthly fill costs more than the entire annual cap, so you clear the deductible and the cost-sharing phase quickly and then pay nothing for the rest of the year. That is a fundamentally different experience from the pre-2025 structure, when a drug like this could cost five figures annually with no ceiling.
How the year plays out
| Month | What you pay | Running out-of-pocket total |
|---|---|---|
| 1 | $615 deductible, then 25% of the rest | About $1,050 |
| 2 | 25% of $2,355 | About $1,639 |
| 3 | The remainder up to the cap | $2,100, cap reached |
| 4 through 12 | $0 for covered drugs | $2,100 |
How this illustration is built: the 2026 standard Part D benefit, meaning a full $615 deductible, then 25% coinsurance, then $0 once your out-of-pocket total reaches $2,100. Your plan may use copays instead of coinsurance, may charge a smaller deductible or none, and may place the drug on a different tier, so treat this as the shape of the year rather than a quote. We are not showing plan-specific copays because we will not publish a number we cannot source.
For anyone on a specialty biologic, this is the single most important change in Medicare in decades: the worst case is now $2,100 rather than unbounded. The practical problem is no longer the annual total but the concentration, since most of that $2,100 lands in the first quarter. That is exactly what the Medicare Prescription Payment Plan exists to solve, by spreading the same total across twelve monthly payments with no interest or fees.

Will I really pay nothing for Enbrel after March?
Once your out-of-pocket total for covered Part D drugs reaches $2,100, your cost sharing goes to $0 for the rest of the calendar year. On a drug at this price you reach that threshold quickly. You still owe your monthly plan premium, and the total resets on January 1.
Are biosimilars cheaper than Enbrel?
Biosimilars to etanercept have been approved in the United States but market availability has been limited by patent litigation. Enbrel's selection for negotiation required that it have no marketed biosimilar competition. Ask your prescriber and pharmacist what is actually available to you.
