Overview
The Affordable Care Act made a series of changes that affected how Medicare pays for and delivers certain benefits. Many changes were phased in over time and were intended to reduce gaps in coverage, limit out-of-pocket exposure for beneficiaries, and discourage improper payments.
For a concise summary of the law and its Medicare-related provisions, see Patient Protection and Affordable Care Act Overview.
Key takeaways
- Part D coverage gaps have been reduced and phased out to lower beneficiaries' drug costs.
- Certain preventive services and annual wellness visits are covered with reduced or no cost sharing.
- Payments to private Medicare Advantage plans were adjusted, affecting plan availability and benefits in some areas.
- Beneficiaries should review plan details each year to confirm coverage and costs.
How it works
Prescription drug coverage under Medicare Part D originally included a coverage gap often called the "donut hole." Over time, reforms reduced the portion of drug costs paid by beneficiaries while in that gap, moving toward closing it and offering discounts on brand-name and generic medications.
Details about enrollment, coverage phases, and how cost-sharing works are complex; for a focused explanation of Part D enrollment and how drug costs are handled, review Understanding Medicare Part D and Enrollment.
What it may cover (and what it may not)
Medicare Parts A and B continue to cover hospital and medical services according to program rules. Preventive screenings, many immunizations, and annual wellness visits are generally covered with little or no cost sharing when delivered by providers who accept Medicare.
Medicare does not generally cover routine dental, vision, or long-term custodial care; beneficiaries often need separate supplemental coverage or private policies for those services. Medicare Advantage plans may offer additional benefits beyond traditional Medicare, but availability and coverage vary by plan and region.
Common mistakes to avoid
Assuming that every plan covers the same services is a common error; benefits, formularies, and cost-sharing differ between original Medicare and Medicare Advantage plans.
Failing to review annual notices and plan formularies can lead to unexpected costs for prescriptions or services that have changed from year to year.
Questions to ask an agent
Ask whether a plan's drug formulary covers your medications and what your expected out-of-pocket costs will be for both the year and when coverage changes occur.
Confirm whether preventive services and annual wellness visits are subject to cost sharing with the specific plan you are considering.
Next steps
Compare your current coverage to available options during open enrollment and check any plan's drug list and provider network before switching.
For guidance that also considers state and program interactions, see Understanding Medicare and Medicaid.
If you need personalized assistance, you can talk to an agent who can review plan details and help you compare options.
