Does Medicare cover Januvia in Florida?

What Januvia is used for

Januvia is a DPP-4 inhibitor tablet. Its FDA label covers improving blood sugar control in adults with type 2 diabetes, along with diet and exercise. It isn't for type 1 diabetes.

This page explains Medicare coverage only. Questions about whether Januvia is right for you belong with your prescriber.

Which part of Medicare covers Januvia

Januvia is a once-daily pill, so it's a Part D drug. Your blood sugar testing supplies are different: meters, test strips and continuous glucose monitors are generally covered by Part B as durable medical equipment, not by your Part D plan. See Medicare Part B.

Is Januvia on Medicare's negotiated-price list?

CMS selected Januvia in the first round of the Medicare Drug Price Negotiation Program. Its negotiated price (the "maximum fair price") took effect January 1, 2026, and Januvia is still on CMS's selected drug list for 2027. A negotiated price is what Medicare drug plans and pharmacies pay; it isn't your copay. What you pay still depends on your plan's cost sharing.

Januvia or Janumet: check the one you take

Januvia is sitagliptin alone. Janumet and Janumet XR combine sitagliptin with metformin in one pill, and CMS selected them separately, in the second round, with a negotiated price effective January 1, 2027. A formulary lists each product separately and can treat them differently, so search for the exact product and strength. If your prescriber is considering switching between them, check both on your plan's formulary first.

What you pay for Januvia in 2027: the out-of-pocket cap

Your cost for Januvia depends on your plan: its deductible, the tier it puts the drug on, and whether you use a preferred pharmacy. This site doesn't list plan costs; your plan's formulary and Evidence of Coverage do. What Medicare sets for everyone with Part D is the limit:

• 2027 out-of-pocket cap: $2,400 (it was $2,100 in 2026). Once what you pay for covered Part D drugs (deductible, copays and coinsurance) reaches the cap, you pay nothing more for covered Part D drugs for the rest of 2027.
• The maximum Part D deductible for 2027 is $700. No plan can set a higher deductible, and some have none.
• Only covered drugs count. If your plan doesn't cover Januvia and you pay cash, or you use a discount card instead of your plan, that spending doesn't count toward the cap.

Spreading the cost: the Medicare Prescription Payment Plan

Every Part D plan and Medicare Advantage plan with drug coverage offers the Medicare Prescription Payment Plan. Instead of paying the pharmacy, you get a monthly bill from your plan that spreads your costs across the calendar year. Medicare.gov says it costs nothing to participate, but it doesn't lower your drug costs; it only changes when you pay. It helps most when costs are high early in the year. To join, call your plan or use its website. More in What is the Medicare Prescription Payment Plan?

Extra Help with Januvia

Extra Help (the Low-Income Subsidy) is a federal program that lowers Part D premiums, deductibles and copays. For 2027, CMS caps Extra Help copays for covered drugs at $5.80 for a generic and $14.40 for a brand-name drug, and some people with full Medicaid pay less. You get Extra Help automatically if you have full Florida Medicaid, SSI or a Medicare Savings Program (QMB, SLMB or QI-1, which you apply for through ACCESS Florida). Otherwise, apply through Social Security at ssa.gov/extrahelp or 1-800-772-1213 (TTY 1-800-325-0778). See Extra Help in Florida and Medicare Savings Programs in Florida.

Getting Januvia covered in Florida

Florida is its own Part D region (PDP Region 11), so each standalone Part D plan sold here is offered in all 67 counties. For 2027, CMS lists 11 standalone Part D plans from 6 companies in Florida. Medicare Advantage choices depend on your county, from 7 plans in Monroe County to 52 in Hillsborough County, and most include drug coverage. Each plan has its own formulary, so one plan's coverage of Januvia tells you nothing about another's. Your county's numbers are on Florida counties.

• Full Florida Medicaid and Medicare: your prescriptions are paid by your Medicare drug coverage, not by Florida Medicaid, and Extra Help is automatic. Most people with full Medicaid, including those who also have Medicare, get their Medicaid services through a Statewide Medicaid Managed Care (SMMC) plan; that plan doesn't replace your Medicare drug coverage. See Florida Medicaid and Medicare.
• Florida state retirees: if you keep a State Group Insurance health plan as secondary coverage to Medicare, it includes prescription drug coverage that the State says Medicare approves as creditable, so you don't need a separate Part D plan. In one of the State's group Medicare Advantage (MA-PD) plans, your Januvia coverage comes from that plan's formulary. Ask People First before you join any outside Medicare plan. See Florida state retirees and Medicare.
• Snowbirds: a Florida Part D plan's service area is Florida. Ask your plan whether its pharmacy network includes pharmacies where you spend the rest of the year, or whether it offers mail order. A Part D plan must disenroll you if you're away from its service area for more than 12 months in a row. See prescriptions for snowbirds.
• Hurricanes: Florida law (s. 252.358) requires state-licensed insurers and HMOs to allow early refills when your county is under a hurricane warning or a state of emergency. Medicare drug plans follow federal rules: CMS expects them to allow early refills after a federal disaster declaration, and Medicare.gov says to contact your plan to replace drugs lost or damaged in a disaster, or to fill at an out-of-network pharmacy when you can't reach an in-network one. See early prescription refills before a hurricane.
• If your Medicare Advantage plan ends in 2027: your plan sends a non-renewal letter, and you have a special enrollment period through February 28, 2027. To keep Januvia covered without a gap, choose new drug coverage by December 31, 2026. See plans ending in 2027.

Florida doesn't have a state drug-assistance program for seniors; Extra Help is the main help with Part D costs. See Does Florida have a state drug assistance program for seniors?

How to check whether a plan covers Januvia

1. Write down the exact drug. Name, strength and how often you take it. A plan can cover one form or strength of Januvia and not another.
2. Look it up in each plan's formulary. Enter your drugs and ZIP code on PlanMatch or Medicare.gov's Plan Finder to see which plans list Januvia and any rules.
3. Read the rules next to the drug. Prior authorization, step therapy or quantity limits mean your prescriber may need to send the plan information before it pays.
4. Check your 2027 notice. Your plan's Annual Notice of Change says whether Januvia stays on the formulary next year. Open Enrollment runs October 15 to December 7, 2026, for coverage starting January 1, 2027.
5. Get help if you want it. You can request a call from a licensed insurance agent, who can compare plans from the companies they work with, or call 1-800-MEDICARE (1-800-633-4227, TTY 1-877-486-2048) for information on all of your options.

If your plan doesn't cover Januvia, you or your prescriber can ask for a coverage determination or a formulary exception. Once the plan has your prescriber's supporting statement, it generally must decide within 72 hours, or 24 hours if your prescriber says waiting could seriously harm your health. New members can usually get a one-time transition supply of a drug they were already taking while they ask for an exception or switch. See Medicare appeals in Florida.
