Medicare Part D in Texas: Formularies, tiers, and pharmacy rules.
Prescription drug coverage protects you from soaring medication costs. With major recent federal reforms—including the \$2,000 annual out-of-pocket cap—matching your exact medications to the right plan formulary has never been more important.
Recent Federal Part D Reforms Benefiting Texans
Historic federal legislation has restructured Medicare Part D, providing unprecedented financial protection for beneficiaries taking maintenance and specialty drugs:
Historic $2,000 Out-of-Pocket Prescription Drug Cap
Under the federal Inflation Reduction Act, beneficiary out-of-pocket spending for covered Part D prescription drugs is capped at $2,000 per calendar year, eliminating the historic coverage gap ("donut hole"). Once you reach $2,000, your covered Part D drugs cost $0 for the remainder of the year.
$35 Monthly Cap on Covered Insulin Products
Beneficiaries who take insulin pay no more than $35 for a one-month supply of each covered insulin product on both standalone Part D plans and Medicare Advantage plans.
Medicare Prescription Payment Plan (MPPP)
Beneficiaries have the voluntary option to spread high out-of-pocket prescription medication costs into predictable monthly payments throughout the plan year rather than paying large sums at the pharmacy counter in January or February.
Preferred Pharmacy Network Savings
Part D plans contract with pharmacies in tiers. Filling prescriptions at a "preferred" Texas retail pharmacy or via mail-order can reduce your copays by 50% or more compared to a "standard" network pharmacy.
How Drug Formularies and Tiers Work
Every Part D plan sorts medications into tiers that dictate what you pay at the pharmacy counter. Knowing your drug’s tier is key to estimating your annual costs:
Tier 1: Preferred Generic
Commonly prescribed generic drugs. Typically carries the lowest copay (often $0 to $5 at preferred pharmacies).
Typical Medications: Common blood pressure, cholesterol, and diabetes maintenance generics.
Tier 2: Generic
Higher-cost generic medications. Modest copays, usually between $5 and $15.
Typical Medications: Specialized generic equivalents or brand generics.
Tier 3: Preferred Brand
Brand-name medications without generic equivalents that the plan has negotiated favorable pricing for. Involves a higher copayment or coinsurance.
Typical Medications: Brand inhalers, cardiovascular therapies, and non-generic medications.
Tier 4: Non-Preferred Drug
High-cost brand medications and non-preferred generics. Beneficiaries typically pay a substantial coinsurance percentage (e.g. 25% to 50%).
Typical Medications: Specialized brand therapies where lower-tier alternatives exist.
Tier 5: Specialty Tier
Extremely high-cost biologics, injectable medications, and cancer therapies. Highest coinsurance percentage.
Typical Medications: Oncology medications, autoimmune treatments, and specialty injectables.

Wellcare by CenteneFrequently Asked Questions About Medicare Part D
How do I avoid the Part D Late Enrollment Penalty (LEP)?
You must maintain continuous "creditable prescription drug coverage" (coverage that pays on average at least as much as standard Part D) without a break of 63 or more consecutive days after your Initial Enrollment Period ends. If you miss this, CMS adds 1% of the national base beneficiary premium per month of delay to your monthly Part D cost permanently.
Can I purchase a standalone Part D plan if I have Medicare Advantage?
Generally, no. If your Medicare Advantage plan includes drug coverage (MAPD), enrolling in a separate standalone Part D plan will automatically disenroll you from your Medicare Advantage plan and return you to Original Medicare. Standalone Part D plans are designed to accompany Original Medicare and Medigap supplements.
Why do my prescription drug costs change each January?
Part D insurance carriers update their drug formularies, tier classifications, deductibles, and pharmacy networks annually. A medication that was on Tier 2 this year might shift to Tier 3 or require prior authorization next year. That is why an annual review during Fall AEP (Oct 15 – Dec 7) is essential.
