Part D: Prescription Drug Plans (PDP)
Part D covers prescription drugs through standalone plans for those on Original Medicare, or as part of a Medicare Advantage bundle. Among the 12 standalone Part D plans in Williamson County, TX, some offer $0 annual deductibles while others charge up to the 2026 maximum of $590. 1 plans are at or below the regional premium benchmark, making them eligible for Low Income Subsidy auto-enrollment. The 2026 $2,000 out-of-pocket cap means drug costs are now more predictable regardless of which plan you choose, but formulary coverage still varies significantly—always verify your medications are covered before enrolling.
Part D Formulary Notice: Each Part D plan has its own formulary (list of covered drugs). The same medication may be on different tiers—or not covered at all—depending on the plan. Always check that your specific medications are covered before enrolling.
2026 Out-of-Pocket Cap: Thanks to the Inflation Reduction Act, your total out-of-pocket drug costs are capped at $2,000 per year in 2026. Once you reach this limit, you pay nothing more for covered Part D drugs for the rest of the year. This eliminates the old "donut hole" coverage gap that previously caused higher costs.
Low Income Subsidy (LIS / Extra Help): If you have limited income and resources, you may qualify for Extra Help paying Part D costs. Visit SSA.gov or call 1-800-MEDICARE.

Local Medicare FAQ: Williamson County, TX
Common decision points based on Williamson County, TX's specific plan market and local healthcare landscape.
How does Williamson County, TX's Medicare Advantage market compare?
Williamson County, TX has 72 Medicare Advantage plans from 13 insurers. This is above the national average of approximately 57 plans, suggesting healthy competition among insurers in this area. The local mix includes 47 HMO and 25 PPO plans. Plan availability updates annually during the Medicare Annual Enrollment Period (October 15 – December 7).
Should I choose an HMO or PPO Medicare Advantage plan in Williamson County, TX?
With 9 hospitals within 25.0 miles, Williamson County, TX has strong provider density. HMO plans (47 available) typically have lower premiums but require referrals and in-network care. PPO plans (25 available) offer more flexibility to see out-of-network providers at higher cost. In Williamson County, TX, HMO plans dominate the market, which often means more competitive HMO pricing. Always verify your doctors are in-network before enrolling in any plan.
What's the real cost of $0 premium plans in Williamson County, TX?
61 plans (85% of available options) in Williamson County, TX charge $0 beyond the standard Part B premium. This high percentage reflects strong insurer competition in the area. However, $0 premium doesn't mean $0 cost. These plans may have higher copays, coinsurance, or out-of-pocket maximums. In Williamson County, TX, maximum out-of-pocket limits range from $3,400 to an average of $7,226. We recommend calculating your total expected annual cost (premium + copays + drug costs) rather than choosing based on premium alone.
How does the 2026 $2,000 drug cap affect Williamson County, TX beneficiaries?
The Inflation Reduction Act capped annual out-of-pocket drug spending at $2,000 starting in 2025, eliminating the old "donut hole" coverage gap. This applies to all 12 standalone Part D plans in Williamson County, TX.
What this means locally:
- Cost predictability — No matter which of the 12 Part D plans you choose, your drug costs are capped at $2,000/year
- $0 deductible options — Some local plans offer $0 deductibles, meaning coverage starts immediately
- Low-income options — 1 plans meet the regional benchmark for Extra Help/LIS eligibility
While the out-of-pocket cap standardizes maximum costs, formulary coverage still varies significantly between plans. A drug that costs $5/month on one plan's formulary might cost $50 on another. Always check that your specific medications are covered and compare tier placement before enrolling.
