One of Medicare’s most valuable — and most overlooked — features is its coverage of free preventive screenings in 2026. Millions of seniors are unaware that Medicare pays 100% for dozens of preventive services, meaning $0 out of pocket when you use a Medicare-participating provider. These free Medicare preventive screenings can catch cancer, heart disease, diabetes, and other serious conditions early — when they are far easier and less expensive to treat.
What Are Free Medicare Preventive Screenings in 2026?
Under Medicare Part B, preventive services are covered at no cost to you when your provider accepts Medicare assignment and the service is considered preventive under Medicare guidelines. The Medicare.gov preventive services page lists every covered screening with its frequency and eligibility criteria.

The Annual Wellness Visit: Your Most Important Free Medicare Benefit
Once you’ve had Part B for more than 12 months, you’re entitled to a free Annual Wellness Visit (AWV) every year. This is different from a routine physical — it is a personalized prevention planning session. During your AWV, your doctor will:
- Review your complete health history and update your medical record
- Screen for cognitive impairment and depression
- Assess your risk for falls and provide prevention referrals
- Review all current medications and check for dangerous interactions
- Create or update your personalized prevention plan
- Provide referrals for any preventive screenings you are overdue for
Important: Medicare does not cover routine physicals — the AWV is a planned prevention visit, not a physical exam. Always call your doctor and specifically request the “Annual Wellness Visit” by name to ensure it’s billed correctly at $0.
Free Vaccines Covered by Medicare in 2026
- Flu shot — one per flu season, $0 under Part B
- Pneumonia vaccines — PCV15 and PPSV23 series, $0
- COVID-19 vaccine and boosters — $0 with no deductible
- RSV vaccine — covered for adults 60+, $0
- Shingrix (shingles) — $0 under Part D since the Inflation Reduction Act
- Tdap — covered under Part D, $0
Important 2026 Changes to Medicare Preventive Screenings
Two changes affect preventive screenings in 2026 that every senior should know:
1. Telehealth restrictions tightened: Many preventive services via telehealth are now only covered if you’re in an approved rural setting or medical facility. Most screenings requiring physical tests or imaging must be done in person — confirm this with your provider before any telehealth appointment.
2. Colorectal screening frequency: CT colonography intervals are now more tightly tied to your risk level. If you’re average risk, you may qualify less frequently. Talk to your gastroenterologist about your personal risk profile.
5 Action Steps to Get All Your Free Medicare Preventive Screenings
- Schedule your Annual Wellness Visit today — Call your primary care doctor and specifically request the “Annual Wellness Visit.” It’s free and unlocks your entire prevention plan.
- Ask for a preventive screening checklist — Ask which screenings you are overdue for based on your age, sex, and health history.
- Confirm your provider “accepts assignment” — Call before any preventive visit. If your provider doesn’t accept Medicare assignment, you may owe a copay.
- Keep preventive and treatment visits separate — If your doctor treats a problem during a screening visit, that portion may be billed as treatment and carry a cost-share. Keep these visits distinct.
- Use Medicare’s “What’s covered” tool — Visit Medicare.gov to see the exact coverage, eligibility, and frequency for every preventive service.
These free Medicare preventive screenings in 2026 are among the most valuable benefits available to seniors. Schedule your Annual Wellness Visit today — it costs nothing and could save your life.
