Know what Medicare Part B covers and what it will cost you
While Medicare Part A covers your room and board at the hospital, Medicare Part B (Medical Insurance) is the true engine of your day-to-day healthcare. For professionals and retirees across Minnesota, Part B is the critical component that covers the medical services and supplies necessary to actually diagnose, treat, and manage your health.
Whether you are aging into the system at 65 or qualifying early due to a disability or End-Stage Renal Disease (ESRD), understanding how Part B functions is essential to protecting your retirement capital.
What Does Medicare Part B Actually Cover?
Part B is heavily focused on outpatient and preventive care. A strategically utilized Part B policy helps cover:
Clinical & Outpatient Care: This includes standard doctor visits, specialist consultations, outpatient surgeries, ambulance services, and outpatient therapies (physical, occupational, and speech).
Durable Medical Equipment (DME): Coverage for essential medical hardware prescribed by your doctor, including wheelchairs, walkers, CPAP machines, and oxygen equipment.
Prosthetics & Orthotics
Comprehensive Preventive Services: Medicare heavily incentivizes keeping you healthy. Part B covers your annual wellness visits, critical disease screenings (cancer, diabetes, cardiovascular), and standard vaccinations (flu, pneumonia, COVID-19).

The Financial Reality: Premium Costs and IRMAA
Unlike Part A, Medicare Part B carries a strict monthly cost structure that must be factored into your retirement planning:
The Standard Premium: By default, most enrollees are assessed a standard monthly premium (adjusted annually by the government), which is typically deducted directly from your Social Security check. While having a qualifying disability or ESRD grants you early access to the Medicare system, it does not automatically waive this federal premium. (However, as your broker, we have strategic avenues to help mitigate or even eliminate this expense. Read our comprehensive guide on Medicare Part C & Premium Relief to learn how).
The High-Earner Surcharge (IRMAA): If your modified adjusted gross income (MAGI) from two years prior exceeds a certain threshold, you will be hit with an Income-Related Monthly Adjustment Amount (IRMAA). This means high-net-worth individuals in the Twin Cities will pay a significant surcharge on top of the standard premium for the exact same Part B coverage.

The Financial Exposure: Deductibles and The 20% Trap
The most dangerous thing a consumer can do is assume Medicare Part B pays for everything in full. Here is your actual financial exposure under Original Medicare:
Cost Type | The Fiduciary Reality |
Annual Deductible | You must meet a set annual deductible before Medicare begins paying its share of your outpatient medical costs. |
The 20% Coinsurance Exposure | Once your deductible is met, Medicare pays 80% of approved costs. You are responsible for the remaining 20%. More importantly, there is no out-of-pocket maximum on this 20%. If you require a highly expensive outpatient surgery or ongoing chemotherapy, your uncapped 20% liability could financially devastate your retirement. |
Enrollment Windows and Lifetime Penalties
In order to enroll in Medicare Part B, you must first be enrolled in Medicare Part A. Failing to enroll in Part B when you are first eligible carries severe, permanent financial consequences. If you do not enroll immediately at the start of your eligibility window, you will acquire a 10% premium penalty for every full 12-month period you delayed. This penalty adds up quickly and lasts for the rest of your life.
Initial Enrollment Period (IEP): Your first opportunity is a 7-month window surrounding your 65th birthday (3 months before, the month of, and 3 months after).
Special Enrollment Period (SEP): If you are unable to enroll during your IEP, you may qualify for an SEP if you (or your spouse) are still actively working and are covered by an employer's health plan that is deemed "creditable" by the Medicare Modernization Act (MMA). This allows you to safely delay Part B without penalty until that corporate coverage ends.
General Enrollment Period (GEP): If you missed your IEP and do not qualify for an SEP, you will need to enroll during the GEP, which spans from January 1st to March 31st each year (and your lifetime penalties will apply).
The Broker Advantage: Capping Your Exposure
Because Medicare Part B leaves you exposed to an infinite 20% coinsurance liability, relying on Original Medicare alone is a massive financial risk.
