Medicare is stronger than ever, with more benefits, better choices, and lower costs to beneficiaries.Expanded Medicare benefits under the health care law (the Affordable Care Act) continue to be available — including certain free preventive benefits, cancer screenings, and an annual wellness visit.Whether you choose Original Medicare or a Medicare Advantage plan, take advantage of Medicare’s Open Enrollment Period to review cost, coverage, or both for 2013. Open Enrollment began Monday and runs through Dec. 7.• More benefits: Certain preventive benefits — including cancer screenings — are available at no cost to patients when furnished by qualified and participating health professionals. The annual wellness visit allows people to sit down and discuss with their doctor their health care needs and the best ways to stay healthy.• Better choices: Medicare will notify beneficiaries about plan performance and use its online Plan Finder to encourage enrollment in quality plans.• Lower costs: Average premiums for 2013 for prescription drug coverage and Medicare health plans will remain stable. People who are in the “donut hole” in Medicare’s prescription drug benefit will enjoy 53-percent discounts on covered brand-name drugs and 21-percent discounts on generic drugs.Your health needs change from year to year. And your health plan may change the benefits and costs each year, too. That's why it’s important to evaluate your Medicare choices regularly. Open Enrollment is the one time of year when all people with Medicare can see what new benefits Medicare has to offer and make changes to their coverage.It’s worth it to take the time to review and compare, but you don’t have to do it alone.
