Does Employer Size Matter for Medicare? Yes — Here's Why
Yes. If your employer has 20 or more employees, employer coverage is primary and you can safely delay Part B. If your employer has fewer than 20 employees, Medicare is primary and you should enroll in Part B when first eligible.
Frequently Asked Questions
- What if my employer has exactly 20 employees?
- An employer with 20 or more employees is considered a large employer for Medicare purposes. The employer plan pays first.
- Does this apply to part-time employees too?
- The 20-employee count typically includes all employees, but the coverage must be based on your active employment to qualify for delayed Part B enrollment.
- What if I'm not sure how many employees my company has?
- Ask your HR department or benefits administrator. The distinction between under 20 and 20+ significantly affects your Medicare obligations.
