Rising healthcare costs remain a major concern for retirees—even those eligible for Medicare. As businesses look to support their workforce post-retirement, 401(h) plans are gaining traction for their ability to pre-fund medical expenses. But how do 401(h) plans and Medicare work together? Understanding this relationship is essential for employers and retirees who want to build a reliable and cost-effective healthcare strategy.
Defining the Basics: 401(h) Plans and Medicare
What is a 401(h) Plan?
A 401(h) plan is a tax-advantaged medical benefit account integrated into a qualified pension or 401(a) retirement plan. Its key attributes include:
- Tax Efficiency: Contributions are tax-deductible, earnings grow tax-free, and withdrawals for qualified medical expenses are tax-free.
- Retiree Support: Created to fund post-employment medical expenses, these plans help employers manage long-term healthcare costs.
- Contribution Cap: IRS regulations cap 401(h) contributions at 25% of the total contributions made to the underlying pension or retirement plan.
What is Medicare?
Medicare is a federal program offering health insurance primarily to those aged 65 and older. It includes:
- Part A (Hospital Coverage): Inpatient services and hospice.
- Part B (Medical Coverage): Doctor visits, preventive care, outpatient services.
- Part C (Medicare Advantage): A private alternative combining A, B, and often D.
- Part D (Prescription Drugs): Coverage for medications.
How 401(h) Plans and Medicare Coordinate in Retirement
When employees retire and become Medicare-eligible, the 401(h) plan acts as a secondary payer, complementing Medicare by covering remaining healthcare costs like copays, deductibles, and premiums.
Coordination of Benefits (COB) Rules
It’s vital to know which payer takes precedence:
| Scenario | Primary Payer | Secondary Payer |
|---|---|---|
| Retired, Age 65+ | Medicare | 401(h) Plan |
| Retired, Under 65 | 401(h) Plan | N/A |
| Actively Working, Age 65+ | Employer GHP | Medicare or 401(h) Plan |
Post-Medicare Eligible Expenses Covered by 401(h)
Qualified expenses under a 401(h) plan include:
- Medicare Parts A, B, C, and D premiums.
- Copayments, coinsurance, and deductibles.
- Some dental, vision, and hearing services (plan permitting).
- Certain long-term care insurance premiums.
