Medicare Cost Changes and Caps for 2027
Federal policy updates and inflation adjustments reshape medical expenses in 2027. Reviewing these benchmark figures allows you to budget accurately for the coming year.
New Part D Drug Spending Cap and Deductible
The federal cap on out-of-pocket prescription drug spending rises to $2,400 in 2027, up from $2,100 in 2026 and $2,000 in 2025. Once you reach $2,400 on covered drugs, you pay $0 for the rest of 2027.
This cap delivers crucial relief for patients managing complex chronic conditions. However, the maximum Part D deductible increases to $700 in 2027, up from $615 in 2026.
While insurance providers can charge a lower deductible, no plan may exceed this statutory limit. Be prepared to cover this upfront cost before your plan begins paying its share.
Projected Part B Premiums and Deductibles
The Medicare Trustees project the standard monthly Part B premium will rise to $209.50 in 2027, up from $202.90 in 2026. The annual Part B deductible is projected to increase to $292 from $283.
Beneficiaries managing tight budgets can explore whether state-assisted Medicare Savings Programs can pay their Part B premiums.
The Centers for Medicare & Medicaid Services (CMS) confirms official Part B figures late each fall. You can verify final numbers on the CMS website before changes take effect.
Standalone Part D Premium Shifts and Coinsurance
In July 2026, CMS decided to end a three-year Part D premium stabilization pilot program one year early. Consequently, many standalone drug plans are implementing steeper monthly premium hikes for 2027.
Policy research from KFF shows beneficiaries will see fewer standalone plan choices in their counties. Additionally, insurers are shifting from flat copays toward percentage coinsurance for brand drugs.
Because coinsurance requires paying a percentage of the total drug price, out-of-pocket expenses can vary each month. Evaluating your medication list during enrollment is vital.
