How Medicare Drug Coverage Really Works
Medicare drug coverage is not the same for everyone. The same medication can be covered, denied, or priced differently depending on how it is administered, which plan you choose, and where you live.
Covered Medications
Many generic and preventive drugs are covered early in the year. These are often low-cost and included across most plans.
Prices That Change
Some brand-name medications cost more early in the year until deductibles or coverage phases are reached. Costs often decrease later.
Denied Drugs
Some medications are excluded by Medicare law regardless of plan type. In these cases, alternatives may exist.
That's why May River Medicare shows you the intelligence first — before any calls, pressure, or enrollment.
Why Some Drugs Are Part B and Others Are Part D
Medicare Part B Drugs
These medications are typically administered by a medical professional in a clinic, hospital, or infusion center.
When paired with a Medicare Supplement, approved Part B drugs are often covered with little or no out-of-pocket cost.
Examples: Keytruda, Opdivo, Remicade, Rituxan
Medicare Part D Drugs
These medications are filled at a pharmacy and fall under prescription drug plans.
Costs may vary based on deductibles, coverage phases, and the specific plan design.
Examples: Metformin, Eliquis, Jardiance, Insulin
The same medication can be treated very differently depending on how it is administered.

Why Your State, County, and ZIP Code Matter
Medicare coverage is not one-size-fits-all. Drug pricing, formularies, and plan availability change based on where you live.
- • Plans are approved at the county level
- • Drug formularies vary by region
- • Deductibles and copays differ by ZIP code
- • Pharmacy networks change locally
- • Prior authorization requirements vary by state
- • Generic availability differs by region
That's why May River Medicare provides ZIP-accurate tools before enrollment.
When a Drug Is Denied — What Options Still Exist
A denial does not always mean the end of the road. Some medications are excluded by Medicare law, while others may have clinically equivalent alternatives that are covered.
Therapeutic Alternatives
In many cases, drugs within the same therapeutic class provide similar clinical outcomes and are covered under Medicare.
Diagnosis-Based Coverage
Coverage can change depending on the diagnosis associated with the prescription, especially for specialty medications.
Plan Structure Matters
Some plans exclude specific drugs while others may include them under different cost-sharing rules.
This is why comparing plans before enrolling is critical.
