Retiree healthcare benefits, often called retiree medical, are one of the trickiest pieces of the benefits puzzle. Unlike pensions, no federal law forces employers to offer them. That makes them voluntary, rare, and mostly a tool for recruitment and retention. For HR leaders, the structure and eligibility rules that follow matter for compliance, cost, and keeping employees informed.
Common structures for retiree health benefits
Employers who offer retiree medical typically pick from a few structures, each with different cost and risk profiles.
1. Group health plan extension
The old standard: retirees stay on the company's group plan, with the employer often still chipping in on premiums. ERISA governs it, and the employer keeps fiduciary responsibility. This model is fading fast in the private sector because costs and accounting liabilities under FASB ASC 715 keep climbing.
2. Group Medicare Advantage plans (EGWPs)
For retirees 65 and older, employers can sponsor a group Medicare Advantage plan under what CMS calls an Employer Group Waiver Plan (EGWP). These are Medicare Advantage (Part C) plans, sometimes paired with Part D drug coverage, and they often carry richer benefits than individual Medigap policies. They can cost the employer less while still giving retirees solid coverage, because Medicare pays the insurer a fixed amount per member.
3. Health Reimbursement Arrangements (HRAs)
HRAs are a popular defined-contribution-style option. The key types:
- Retiree HRA: The employer funds an account to reimburse retirees for medical expenses and premiums. Caps keep employer costs predictable.
- Individual Coverage HRA (ICHRA): For retirees under 65, employers give a tax-free allowance to buy an individual plan. For Medicare-eligible retirees, it can reimburse premiums once they have Medicare Parts A and B together, or Part C.
- Qualified Small Employer HRA (QSEHRA): Smaller companies use this to offer a similar allowance.
4. Pure defined contribution / voucher system
The employer gives a fixed dollar amount as a voucher or stipend, and retirees buy their own coverage on the individual market or through Medicare. All the risk of picking a plan and market swings lands on the retiree. For the employer, costs stay predictable.
Who qualifies for retiree healthcare benefits?
Eligibility isn't automatic. The plan document sets the rules. Common gates include:
- Length of service: Usually 10, 15, or 20 years.
- Age at retirement: Often 55, 62, or the company's normal retirement age.
- Pension eligibility: Retiree medical is often tied to qualifying for a traditional defined benefit pension.
- Medicare status: Some plans are only for pre-65 retirees, others only for Medicare-eligible. Subsidies often shift at 65.
- Employment classification: Typically salaried, full-time employees. Union contracts may have separate provisions.
Promises of retiree health benefits can become a lifetime obligation under ERISA if the plan language says so. In M&G Polymers USA, LLC v. Tackett (2015), the Supreme Court rejected a presumption that these benefits vest for life and directed courts to apply ordinary contract principles to the actual plan and agreement language. Clear plan documents and SPDs that reserve the right to amend or terminate generally protect an employer. Vague, open-ended promises invite litigation. Communicate precisely.
Retiree coverage today: shrinking and moving to Medicare Advantage
Employer-sponsored retiree coverage today has two defining facts. The pool of employers offering it keeps shrinking: the share of large employers offering retiree health benefits to active workers fell from 66% in 1988 to 24% in 2024, per the KFF Employer Health Benefits Survey. Among employers that still offer coverage to Medicare-age retirees, the design is moving to Medicare Advantage. In 2024, 56% of those employers offered coverage through a Medicare Advantage contract, up from 26% in 2017. Roughly 5 million Medicare Advantage enrollees get coverage through an employer plan, according to Urban Institute analysis of CMS enrollment files. Employers make the move for steadier pricing and richer supplemental benefits than individual Medigap. The tradeoff is a narrower network than traditional Medicare with a supplement, and retirees who leave the group plan may not find an equivalent policy on their own. For HR teams, the decision turns on whether network limits are acceptable in exchange for lower, more predictable employer costs.
The modern challenge and a new approach
The old model is buckling. Employers face large, unpredictable liabilities, and retirees fear losing coverage or watching costs climb. That pressure is pushing benefits design beyond subsidizing care and toward building long-term security. WellthCare™, the first Health-to-Wealth™ Benefit System, works alongside an existing health plan and gets used first. Employees receive $0-co-pay care, earn reward dollars at the WellthCare Store™, and build retirement savings automatically through verified preventive care.
Preventive care drives the system. When an employee completes a health assessment, screening, or scan, the platform verifies it and rewards the action. Rewards take two forms: store dollars employees can spend now at the WellthCare Store, and automatic retirement contributions funded by savings the employer commits. Over a career, small preventive steps compound into meaningful retirement security.
What to do next
- Audit your obligations. Review plan documents and communications to know exactly what you've promised and your liability under FASB ASC 715.
- Model defined contribution strategies. Look at HRAs and voucher systems to move from open-ended liability to predictable costs.
- Connect with financial wellness. Link retiree health planning with 401(k) and financial education. HSAs are a portable retiree health savings tool.
- Explore next-generation solutions. Check out platforms that build health and wealth together. Rewarding prevention creates better outcomes and lower costs.
- Communicate with radical clarity. Employees need to understand the conditions and potential changes to retiree medical so they can plan accordingly.
Structuring retiree health benefits is one of the most strategic decisions a company can make. The strongest models fund care while building health and wealth together.
