Medicare late-enrollment penalties can increase your monthly costs for years—and in some cases for as long as you have the coverage. Learn how the common penalties work, when they may apply, and what documentation may help you avoid them.
Most people receive premium-free Part A. If you must buy Part A and do not enroll when first eligible, the monthly premium may increase by 10%. The higher premium is generally paid for twice the number of years you delayed enrollment.
The Part B penalty is generally 10% of the standard Part B premium for each full 12-month period you could have had Part B but did not. It is usually added to your monthly Part B premium for as long as you have Part B. Qualifying coverage based on current employment may allow a Special Enrollment Period.
The Part D penalty may apply after 63 consecutive days without Medicare drug coverage or other creditable prescription coverage. It is generally calculated as 1% of the national base beneficiary premium multiplied by the number of full uncovered months, rounded to the nearest ten cents.
The Income-Related Monthly Adjustment Amount, or IRMAA, is an additional amount some higher-income beneficiaries pay for Part B and Part D. It is based generally on tax information from two years earlier. Certain life-changing events may support an appeal.
Employer or union coverage based on current employment may protect against a Part B penalty. Creditable drug coverage may protect against a Part D penalty. COBRA, retiree coverage, Marketplace coverage, and VA coverage do not all work the same way for every Medicare rule.
Save employer coverage letters, creditable drug coverage notices, termination letters, pay stubs, benefit statements, and enrollment confirmations. Documentation can be critical when Social Security or a drug plan reviews whether a penalty applies.
Medicare rules, plan availability, provider networks, drug formularies, benefits, premiums, and eligibility can vary by person, county, and year. A licensed Accurate Health Plans agent can help you compare the details that affect your decision.
A penalty may be corrected when records show you had qualifying coverage, were enrolled timely, or qualify for a protected enrollment circumstance. The process depends on the penalty and facts.
Generally, COBRA is not coverage based on current employment for the Part B Special Enrollment Period. Do not delay Part B solely because you have COBRA without reviewing your deadline.
VA prescription coverage is generally considered creditable for Part D, but beneficiaries should keep annual notices and consider how they will obtain prescriptions outside the VA system.
