Employee Turning 65: Medicare Checklist for Texas Employers

Check payer order, Medicare dates, drug notices, HSA deposits and family coverage without choosing Medicare coverage for an employee.

3 min read By Dustin Neider

Key Takeaways

  • Confirm payer order using the correct employer count, not enrollment count.
  • COBRA does not extend the job-based Part B special enrollment window.
  • Check creditable drug coverage and required notices separately from Part B.
  • Medicare enrollment, including retroactive months, affects HSA contributions.
  • Keep personal Medicare decisions with the employee and Medicare or Social Security.

For an employee turning 65, Texas employers should confirm payer order, employment and coverage dates, creditable drug coverage, HSA deposits and effects on covered family members before processing a plan change. HR supplies plan facts and neutral assistance; the employee confirms personal Medicare enrollment requirements with Medicare or Social Security rather than relying on a birthday alone.

Who pays first: the group plan or Medicare?

PCI decision graph: age-65-or-older Medicare beneficiaries with current-job group coverage; the group plan generally pays first with at least 20 employees, Medicare generally pays first below 20 in single-employer plans; confirm multiple-employer arrangements.

For age-65-or-older Medicare beneficiaries with coverage through their own or a spouse’s current employment, CMS Medicare Secondary Payer guidance generally puts the group plan first with 20 or more employees, including exactly 20. Medicare generally pays first in a single-employer plan with fewer than 20. Do not substitute the number enrolled for the required employer count.

Multiple- or multi-employer arrangements require separate review: another participating employer with at least 20 employees may affect payer order. A small-employer exception requires approval. Get written confirmation from the plan team, including the count, arrangement and any approved exception. Where Medicare is secondary, follow CMS nondiscrimination requirements and do not steer eligible older workers off the group plan.

What dates should HR confirm?

Medicare explains enrollment dates: the initial enrollment period generally lasts seven months around age 65. In eligible current-job coverage cases, the Part B special enrollment period ends eight months after employment or group coverage ends, whichever happens first. COBRA does not extend that window. Have the employee confirm eligibility and effective dates before a termination or retirement change.

What drug notice belongs in the file?

CMS creditable-coverage guidance explains that creditable prescription coverage is expected to pay, on average, as much as standard Medicare drug coverage. Required notices to Medicare-eligible covered people include the annual notice before October 15 and other specified times. Obtain the current determination, identify who sends notices and retain delivery evidence.

Part D has separate timing: Medicare describes potential late-enrollment penalties after 63 days or more without creditable drug coverage under the applicable conditions. Do not use Part B’s eight-month window as a drug-coverage deadline.

How should payroll handle HSA deposits?

Under IRS Publication 969, the HSA contribution limit is zero beginning with the first Medicare-enrolled month, including retroactive months. Premium-free Part A can start six months before late enrollment, but not before the month of turning 65 under the stated rule. Confirm actual effective dates and obtain tax-advisor instructions for both employee and employer deposits; do not apply an automatic birthday cutoff.

What should the final checklist include?

Assign an owner and follow-up date for payer order, employment and coverage end dates, drug notices, HSA review and each covered family member. Medicare recommends speaking with the benefits administrator before changing employer coverage. Save the plan’s answer for the employee and each dependent before acting.

A neutral HR message can invite the employee to review current plan documents with the benefits contact, confirm Medicare dates with Medicare or Social Security, and review HSA timing with a tax advisor. Keep the coverage decision with the employee; seek benefits counsel before proposing any payment or waiver tied to leaving the group plan.

Frequently Asked Questions

Who pays first with exactly 20 employees?

For an age-65-or-older Medicare beneficiary covered through current employment, the group plan generally pays first at 20 or more employees. Have the plan confirm the count and any multiple-employer arrangement.

Does COBRA extend the Part B window?

No. In eligible job-based coverage cases, the special enrollment window ends eight months after employment or group coverage ends, whichever occurs first; COBRA does not extend it.

Why does Part A backdating matter for an HSA?

HSA contributions are not allowed for Medicare-enrolled months, including retroactive months. Confirm the actual Medicare start date and have a tax advisor review both employer and employee contributions.

Can changing the employee’s coverage affect family members?

Yes. Confirm the effect for every covered family member with the benefits administrator before processing a change; do not assume their coverage continues unchanged.
