Understanding Medicare Part D Coverage Changes for 2026
Medicare Part D assists approximately 54.8 million older Americans-around 80% of all Medicare enrollees-in affording prescription medications, according to the Kaiser Family Foundation. However, coverage rules and formularies are subject to change, meaning that even with a valid prescription, your medication might not be covered under Part D.
Before refilling your prescriptions in 2026, it is important to review the latest coverage details to avoid unexpected out-of-pocket expenses.
What Is Medicare Part D?
Medicare Part D is the prescription drug benefit offered through private insurance companies like Humana, Aetna, and UnitedHealthcare. These insurers must adhere to federal guidelines regarding covered medications and how their formularies are structured.
Most Part D plans categorize drugs into tiers that impact copayment amounts:
- Tier 1: Lowest copayments, typically for preferred generic drugs
- Tier 2: Moderate copayments, covering many generic medications
- Tier 3: Higher copayments for preferred brand-name drugs and some costly generics
- Tier 4: Even higher copayments for non-preferred drugs, both brand-name and generic
- Tier 5: Highest copayments for specialty drugs with unique or very high costs
Enrollment and Costs
Eligible individuals can sign up for Medicare Part D when they first qualify for Medicare (usually at age 65) or during the annual open enrollment period. Plans typically require monthly premiums, deductibles, and varying cost-sharing depending on the tier and medication.
What Does Medicare Part D Cover?
Part D generally covers FDA-approved prescription medications deemed medically necessary and listed on the plan’s formulary. Certain “protected classes” of drugs must be covered, including antidepressants, anticonvulsants, antiretrovirals, immunosuppressants, antipsychotics, and anticancer medications.
What Is Not Covered?
There is no universal list of excluded drugs across all Part D plans, but Medicare mandates exclusion of entire drug categories such as those for weight management, cosmetic uses, and erectile dysfunction.
For 2026, some commonly prescribed medications excluded from coverage include:
- Humira: Due to its high cost, many plans favor lower-cost biosimilar alternatives. Patients prescribed Humira could face out-of-pocket costs exceeding $6,900 per month.
- Erectile Dysfunction Drugs: Medications like Viagra and Cialis are generally excluded unless prescribed for other medical conditions, such as pulmonary hypertension.
- Weight-Loss Drugs: Medications such as Wegovy and Ozempic (when used specifically for weight loss) and Xenical are excluded.
However, drugs like Ozempic may be covered if used to treat Type 2 diabetes.
- Hair Loss Treatments: Drugs like finasteride and minoxidil used solely for hair loss are not covered.
- Cosmetic Drugs: Medications prescribed for cosmetic purposes, including Renova, are excluded.
- Certain Cough Medications: Prescription cough syrups like Robitussin AC and some Phenergan formulations are generally not covered.
- Over-the-Counter (OTC) Products: Even if prescribed by a doctor, OTC drugs such as MiraLAX, Claritin, or Tylenol are not covered unless a prescription-only, higher-strength version is required.
- Eyewear: Prescription glasses, contact lenses, and routine eye exams are not covered, though medications for eye diseases are included.
Changes in Coverage and Cost Controls
Some high-cost brand-name drugs face stricter restrictions in 2026, including requirements for step therapy or prior authorization. Plans increasingly encourage the use of generic alternatives to manage costs.
What To Do If Your Medication Isn’t Covered
If your medication is not on the formulary, your doctor can request an exception or suggest a covered alternative. Appeals may be possible, particularly if you cannot tolerate lower-cost options.
Other options include using discount programs such as GoodRx, manufacturer coupons, or pharmacy savings plans. Some patients may also consider purchasing medications from international sources. Additionally, switching to a different Part D plan during open enrollment may improve coverage and reduce costs.
Key Takeaways
Medicare Part D offers significant prescription coverage but excludes certain drug categories like weight management, sexual dysfunction treatments, and cosmetic medications. With ongoing shifts toward generics and cost management strategies, staying informed about your plan’s formulary is essential.
Although the 2026 open enrollment period has ended, eligible individuals can still enroll late but may face penalties unless they had comparable coverage previously.
