Turning 65 does not always mean retiring. Many people in San Antonio, Texas, continue working well beyond their 65th birthday. However, one important question can create confusion: should you enroll in Medicare now or delay it while keeping your employer health insurance? The right answer depends on your employment status, the size of your employer, the type of health coverage you have, and whether you contribute to a Health Savings Account (HSA).
Making the wrong decision can lead to coverage gaps or late-enrollment penalties. FutureWise Insurance helps individuals understand the factors that may affect their Medicare decisions so they can review their options with greater confidence.
Medicare and Active Employer Coverage After Age 65
If you are still actively working at 65 and have group health coverage through your current employer, or through your working spouse’s employer, you may qualify to delay Medicare Part B without a late penalty. Generally, the Special Enrollment Period allows eligible individuals to enroll while they still have qualifying job-based coverage or during the 8-month period after employment or qualifying coverage ends, whichever happens first.
The phrase current employment is important. Retiree coverage and COBRA do not work the same way as active employer coverage for this Part B enrollment protection. Medicare specifically notes that COBRA does not count as current group health plan coverage for extending this Special Enrollment Period.
For employees who are unsure about enrollment timing, Medicare Help for Working Seniors in San Antonio, TX can be especially valuable because the decision should be based on the details of the actual employer plan rather than age alone.
The 20-Employee Rule Can Change Which Coverage Pays First
Employer size is a major consideration. According to CMS Medicare Secondary Payer rules, if a person is 65 or older and has coverage based on current employment, a group health plan generally pays first when the employer has 20 or more employees, with Medicare paying second when applicable. When the employer has fewer than 20 employees, Medicare generally pays first. Multi-employer plans can have different rules, so employees should verify how their specific plan coordinates benefits.
This is why small business owners and employees in Texas should not automatically assume they can safely delay Medicare. If Medicare is expected to be the primary payer and you do not enroll when required, your employer plan may not cover costs in the way you expect.
How HSA Contributions Affect Medicare Decisions
The situation becomes more complex if you have a High Deductible Health Plan and contribute to an HSA. Once you are enrolled in Medicare, you generally cannot continue making HSA contributions for months when you have Medicare coverage. Medicare Part A can also be retroactive for up to six months in certain situations, meaning HSA contributions made during retroactive coverage may become excess contributions.
For this reason, employees who plan to enroll in Medicare after delaying it should coordinate their HSA contribution timeline carefully. A review with a qualified tax professional and benefits specialist may help avoid unexpected tax issues.
What Happens When You Retire or Lose Employer Coverage?
When your active employment or qualifying employer coverage ends, timing becomes critical. Medicare’s current guidance provides an 8-month Special Enrollment Period for eligible individuals to enroll in Part B after employment or group health plan coverage ends, whichever happens first. COBRA does not stop or extend this 8-month period. Waiting until COBRA ends before applying for Part B may therefore create a gap in coverage and could result in a late-enrollment penalty.
For someone transitioning into retirement, Medicare and Employer Coverage in San Antonio, TX should be reviewed before the last day of work whenever possible. Understanding when employer benefits end, when Medicare should begin, and whether prescription drug coverage is creditable can help make the transition smoother.
Should You Enroll in Part A and Delay Part B?
Some working individuals may choose to enroll in premium-free Part A while delaying Part B, but this is not the best choice for everyone. In particular, enrolling in Part A affects HSA contribution eligibility. Before making this decision, compare your employer coverage, out-of-pocket costs, Medicare eligibility, and HSA plans.
There is no single answer that fits every working adult in San Antonio. Your employer’s benefits administrator can explain how the plan coordinates with Medicare, while Medicare and licensed insurance professionals can help you understand applicable enrollment rules and available coverage choices. FutureWise Insurance can help you have a clearer conversation about your options without relying on assumptions.
5 Important Facts for Working Texans Turning 65
- Your Initial Enrollment Period generally lasts seven months. It begins three months before the month you turn 65 and ends three months after your birthday month.
- The Part B Special Enrollment Period can last eight months. For eligible people with coverage based on current employment, it runs after employment or qualifying group health coverage ends, whichever happens first.
- Employer size matters. For working people age 65 or older, CMS generally lists the group health plan as primary for employers with 20 or more employees and Medicare as primary for employers with fewer than 20 employees, subject to applicable plan rules and exceptions.
- COBRA does not pause the Part B Special Enrollment Period. Medicare advises that the 8-month period continues whether or not you elect COBRA.
- Medicare enrollment affects HSA contributions. The IRS states that your HSA contribution limit becomes zero beginning with the first month you are enrolled in Medicare, including applicable retroactive coverage periods.
