Medicare Part B

The Basics

What is Medicare Part B?

Medicare Part B is the component of Original Medicare that primarily helps cover medically necessary outpatient services and preventive care.

While Medicare Part A generally focuses on hospital-related services, Medicare Part B helps cover services such as doctor visits, lab tests, diagnostic screenings, medical equipment, ambulance transportation, and other outpatient services. Understanding what Medicare Part B covers can help you better prepare for healthcare expenses during retirement.

Costs

How much does Medicare Part B cost?

For 2024, the standard Part B costs are as follows.

$174.70 / month

Standard Part B premium in 2024 for individuals with an annual income of $103,000 or less (or married couples with a combined income of $206,000 or less).

$240 / year

Annual Part B deductible in 2024 that you pay before Medicare begins covering most outpatient services.

20% coinsurance

After meeting the deductible, you're generally responsible for 20% of the Medicare-approved cost for most outpatient services covered under Original Medicare.

If you receive Social Security benefits, your Part B premium is typically deducted automatically from your monthly payment. If you do not receive Social Security benefits, you can choose to be billed directly for your premium payments.

Why It Matters

Why Medicare Part B matters

Healthcare expenses can increase as we age. Medicare Part B helps provide access to important outpatient care, preventive services, and medical treatments that support overall health and well-being.

Without Part B coverage, individuals may face significant out-of-pocket costs for doctor visits, medical testing, outpatient procedures, and other healthcare services.

Understanding your enrollment opportunities and coverage options can help you avoid unexpected expenses and coverage delays.

Enrollment

When can I enroll in Medicare?

Medicare has several enrollment periods, each with its own timing and rules.

Initial Enrollment Period (IEP)

Your first opportunity to enroll in Medicare — a 7-month window:

  • The 3 months before your 65th birthday month
  • Your birthday month
  • The 3 months after your birthday month

Annual Enrollment Period (AEP)

October 15 – December 7. During AEP, you can:

  • Change Medicare Advantage plans
  • Join, switch, or drop a Part D prescription drug plan
  • Return to Original Medicare

Changes take effect on January 1.

Medicare Advantage Open Enrollment

January 1 – March 31. If you're enrolled in a Medicare Advantage plan, you can:

  • Switch to another Medicare Advantage plan
  • Return to Original Medicare
  • Add a Part D plan if returning to Original Medicare

Special Enrollment Period (SEP)

You may qualify if certain life events occur, such as:

  • Moving to a new service area
  • Losing employer or other health coverage
  • Gaining eligibility for Medicaid or Extra Help
  • Changes to your current Medicare plan
  • Qualifying for a Special Needs Plan (SNP)

SEP rules and timing vary depending on the situation.

General Enrollment Period (GEP)

January 1 – March 31. If you missed your Initial Enrollment Period and do not qualify for a SEP, you can enroll during the GEP. Coverage typically begins the month after enrollment.

Time for a Review

Already enrolled in Medicare? It may be time for a review

Your healthcare needs may change over time. Prescription needs, doctor networks, healthcare costs, and coverage preferences can all evolve from year to year.

A Medicare review can help ensure your current coverage continues to align with your needs and budget. Our team can help you understand available options and answer questions about your existing coverage.

Yes. If you are covered by a health plan through your current employer (or your spouse's current employer), you may be able to delay enrolling in Part B without paying a late enrollment penalty. Once your employment or employer-sponsored coverage ends (whichever occurs first), you generally have an 8-month Special Enrollment Period to enroll in Part B. Important: COBRA and retiree health coverage are not considered active employer coverage and do not qualify you for a Part B Special Enrollment Period.
Medicare Part B does not cover certain routine or non-medically necessary services, including:
  • Routine physical exams
  • Cosmetic surgery
  • Most dental care and dentures
  • Routine vision care, eyeglasses, and contact lenses
  • Hearing aids
  • Most alternative therapies, such as massage therapy
  • Long-term custodial care
  • Most prescription medications (covered under Medicare Part D)
Possibly. If you delay enrolling in Medicare Part B and do not qualify for a Special Enrollment Period, you may have to pay a late enrollment penalty. The penalty is generally added to your monthly premium and may continue for as long as you have Medicare coverage.
