## Medicare Part D isn't one-and-done
Enrolling in Medicare Part D isn't a one-and-done decision. Leaving your plan on autopilot during open enrollment could cost hundreds in unexpected premiums and out-of-pocket fees.
## 2027 plan costs vary widely
The cheapest plan by monthly premium is rarely the most cost-effective option overall. Always sort plans by lowest drug plus premium cost to see true out-of-pocket costs.
## Formularies change yearly
Your insurer's formulary and tier structures likely change yearly. Generic, preferred brand, or non-preferred brand drugs affect your costs significantly.
## 2027 deductible limit
For 2027, the federally mandated maximum deductible a Part D plan can charge is $700, $85 more than 2026's $615.
## Donut hole eliminated
The infamous coverage gap or 'donut hole' was officially eliminated as of January 1, 2025. The 2027 out-of-pocket cap is $2,400, a $300 increase over 2026's $2,100.
## No spousal discounts
Most spouses don't take the same medications. One plan may cover your drugs better while another covers your spouse's needs.
## Medicare prescription payment plan
You can opt into the Medicare prescription payment plan to spread drug costs into capped monthly installments instead of paying a large sum at the pharmacy.
## Fewer stand-alone plans
The number of stand-alone plans decreased from 30 in 2021 to 11 in 2026, a 22% drop over five years, according to KFF.
## Premium subsidies end in 2027
The IRA premium stabilization demonstration ends in 2027, ending federal premium subsidies that helped keep monthly premiums stable in 2025 and 2026.
## Avoid late enrollment penalty
If you don't enroll in Part D when first eligible and go 63+ days without 'creditable' drug coverage, you face a permanent late enrollment penalty.
## 2027 out-of-pocket cap
For 2027, the out-of-pocket cap is $2,400, after which copays and coinsurance drop to $0.
## Key takeaway

Medicare Part D enrollees face 2027 changes including higher deductibles, no spousal discounts, and end of premium subsidies.
