If you or someone you care for takes Farxiga, you’ve likely seen the pharmacy price and wondered how much Medicare covers. The short answer is yes — Medicare covers it — and in 2026 there’s some encouraging news on cost.
Yes, Part D covers Farxiga
Farxiga (the brand name for dapagliflozin) is covered under Medicare Part D, the part of Medicare that handles prescription drugs you take yourself. You get Part D either through a standalone drug plan that pairs with Original Medicare, or built into a Medicare Advantage plan.
What Farxiga treats
Farxiga is an SGLT2 inhibitor — a once-a-day pill. Part D covers it when it’s prescribed for one of its approved uses:
- Type 2 diabetes — to help control blood sugar
- Heart failure — to lower the risk of related complications
- Chronic kidney disease — to help slow the loss of kidney function
One thing to be clear about: Medicare is not allowed by law to cover any drug used for weight loss. Farxiga is covered for the conditions above — not for losing weight.
Brand vs. generic
Right now, Farxiga is a brand-only medication; there isn’t a generic dapagliflozin on Part D plans yet. That matters for your wallet, because generics typically sit on the lowest, cheapest tiers. Until a generic arrives, Farxiga is filled as the brand and priced accordingly.
How Medicare covers it — and what tier to expect
On most Part D plans, Farxiga lands on a brand-name drug tier because there’s no generic version. A higher tier usually means a higher copay than you’d pay for an everyday generic.
Here’s the important part: which tier Farxiga sits on, and what it costs, varies by plan and changes each year. Two people on the same medication can pay very different amounts depending on the plan they chose. The way to know your situation is to check the plan’s drug list — called the formulary. You can do that quickly with the Formulary Lookup tool to see whether Farxiga is covered, what tier it’s on, and whether any restrictions apply.
Coverage rules to expect
A couple of common hurdles show up with brand drugs like Farxiga:
- Prior authorization. Some plans want your doctor to confirm you’re using Farxiga for an approved condition before they’ll cover it. Your prescriber submits the medical documentation.
- Step therapy. A plan might ask you to try a preferred (often lower-cost) drug first, and only cover Farxiga if that one doesn’t work for you.
These rules differ from plan to plan, so it’s worth checking before you enroll rather than being surprised at the pharmacy counter.
Coverage exceptions and appeals
If a plan won’t cover Farxiga, or places it on a tier you can’t manage, you’re not stuck. You and your prescriber can request a coverage exception — for example, to cover a drug that’s not on the formulary or to lower its tier. Your doctor explains why you need this specific medication. If the plan says no, you have appeal rights and can take it further. It’s a normal process, and a good prescriber’s office handles these requests regularly.
The 2026 negotiation and the $2,000 cap
Two cost changes are worth knowing about for 2026.
First, Farxiga is one of the first 10 drugs Medicare negotiated a price on directly, and that negotiated price took effect January 1, 2026. In plain terms, the government and the drugmaker agreed on a lower underlying price. That’s a genuine benefit. But a lower negotiated price doesn’t become one fixed copay for everyone — what you pay still depends on your plan, the tier Farxiga is on, and where you are in your yearly costs. So be wary of any headline promising an exact dollar figure.
Second — and for many people this matters even more — every Part D plan now caps your out-of-pocket prescription costs at $2,000 for the year. Once your spending hits $2,000, you pay nothing more for covered drugs for the rest of the calendar year. The old “donut hole” gap is gone. If Farxiga is one of several prescriptions you fill regularly, that cap puts a firm ceiling on a cost that used to feel open-ended.
To see what Farxiga might actually cost you, run it — along with your other medications — through the Drug Cost Calculator to estimate your spending across the year under a given plan. If you want the bigger picture, the Medicare Cost Estimator can help you weigh premiums and drug costs together.
Alternatives to discuss with your doctor
If cost or a coverage rule becomes a roadblock, there may be other options in the same drug family worth raising with your physician. Another SGLT2 inhibitor, empagliflozin (Jardiance), treats similar conditions — you can read more in our guide on whether Medicare covers Jardiance. I’m an insurance agent, not a doctor, so any switch is a medical decision: bring it to your physician, who knows your health history.
Questions to ask your doctor
- Is Farxiga the right choice for my condition, or would another SGLT2 inhibitor work as well?
- If my plan requires step therapy, what would I need to try first?
- Can you help with a prior authorization or coverage exception if my plan asks for one?
