Delaying Medicare While Contributing to an HSA
Lena is 64 years and 10 months old. She works full time for a private employer with 40 employees and is covered by the company’s HDHP; her spouse is on the same plan. Lena contributes $300 per month to her HSA, and the employer adds $1,000 per year. She is not receiving Social Security and does not plan to retire until age 68. The employer’s prescription drug notice says the drug coverage is creditable. Lena has no regular prescriptions but wants to avoid a Part B late enrollment penalty and wants to keep contributing to her HSA as long as possible. She asks whether she should enroll in Medicare at 65, whether Part A alone would solve the penalty issue, and what happens to her HSA if she enrolls in Part A now.
1. What is the strongest permissible enrollment strategy for Lena at 65 if her goal is to keep HSA contributions and avoid penalties? Explain the trade-offs.

Because Lena is not receiving Social Security, she will not be auto-enrolled at 65. Her employer plan is based on current employment and the employer has 40 employees, so the working-aged rules let her delay Part B without a penalty while she remains covered. But Part A is not a free way to preserve HSA eligibility: entitlement to Part A, even premium-free, ends her ability to make new HSA contributions, including employer contributions. If preserving the HSA is her top priority, she should delay both Part A and Part B, keep creditable drug coverage, and enroll in Part B within eight months after employment or coverage ends. If she values hospital coverage more, she can take Part A and stop HSA contributions, but she must correct any excess contributions. Part A alone does not create a Part B penalty; the employer coverage is what protects the Part B SEP.
2. Lena says she will enroll in Part A only because it is premium-free and keep making HSA contributions until she retires. What should the agent tell her, and what documentation should be kept?

Tell her the premium-free label is irrelevant to HSA eligibility. Medicare entitlement is the disqualifier. She must stop employee and employer HSA contributions before the month Part A begins; she may still spend existing HSA funds on qualified medical expenses. If contributions were made for months after entitlement, they are excess and should be corrected with the HSA custodian and tax adviser. Document the employer creditable coverage notice, proof of current employment-based coverage, and the date she intends to stop contributions. If she wants to keep contributing until retirement, the cleaner path is to postpone Part A as well as Part B, assuming she remains covered by the group plan.
