What counts toward the $2,400 cap
- Your annual Part D deductible spending (up to $615) on covered formulary drugs.
- Your copayments and coinsurance at network pharmacies for drugs on the plan formulary.
- Certain third-party payments and manufacturer discount credits defined under CMS True Out-of-Pocket (TrOOP) rules.
What does NOT count toward the $2,400 cap
- Monthly Part D or Medicare Advantage plan premiums.
- Medications that are not on the plan formulary unless the carrier approves a formulary exception.

- Medicare Part B drugs administered in a doctor office or outpatient infusion clinic (such as Watson Clinic or Hollis Cancer Center).
Common questions
What is the 2027 Medicare Part D out-of-pocket cap in Florida?
For 2027, the annual Medicare Part D out-of-pocket cap (TrOOP) is $2,400, up from $2,100 in 2026. The maximum standard Part D deductible for 2027 is $615, up from $590 in 2026. Once your out-of-pocket spending on covered Part D formulary drugs reaches $2,400, you pay $0 for covered Part D prescriptions for the remainder of the calendar year.
Why can a prescription still cost more than $2,400 if it is not on my 2027 formulary?
The $2,400 Part D cap applies only to drugs covered on your plan formulary or approved through a formal formulary exception. If a carrier removes a brand-name or specialty drug from its 2027 formulary and no exception is granted, paying cash at the pharmacy does not count toward the $2,400 cap.
Does the $2,400 Part D cap include monthly premiums or Part B infusions?
No. Monthly Part D or Medicare Advantage premiums are paid separately and do not count toward the $2,400 pharmacy cap. Medications administered in a physician office or outpatient infusion center are generally billed under Medicare Part B medical benefits rather than Part D.
How does the Medicare Prescription Payment Plan work with the $2,400 cap in 2027?
The Medicare Prescription Payment Plan allows Part D enrollees to opt in and spread covered out-of-pocket prescription costs across monthly bills through the calendar year instead of paying large upfront amounts at the pharmacy counter in January or February. It does not lower total drug cost, but it caps and smooths monthly cash flow.
