Can You Be Denied Health Insurance Through Your Employer?

Employer-sponsored health insurance is a cornerstone of workplace benefits, but many wonder: can you be denied coverage through your employer? Understanding the rules around eligibility, denials, and appeals is essential for protecting your healthcare access.

What Counts as Denial of Employer Health Insurance?

Employers may deny health insurance enrollment for several reasons: incomplete paperwork, unpaid premiums, violations of plan rules, or failure to meet eligibility criteria. Most commonly, denial occurs when an employee misses the open enrollment window or fails to maintain continuous coverage. Employers also have the right to terminate coverage if an employee is laid off or terminated, though laws protect against abrupt, unjust denials, especially during health crises.

Eligibility Rules That Affect Coverage

To qualify for employer-sponsored insurance, employees typically must meet three key eligibility criteria: employment status, full-time or part-time requirements, and continuous coverage duration. Full-time employees (usually 30+ hours/week) usually get automatic coverage. However, temporary or part-time workers may face restrictions. Employers often require proof of enrollment during open enrollment to confirm eligibility. Missing this window can trigger automatic denial, even for compliant employees. Always verify your status early and confirm enrollment status each year.

How Employer Denials Happen and What You Can Do

Denials can occur due to documentation errors, failure to pay premiums, or non-compliance with pre-existing condition rules — though recent reforms limit such exclusions under the Affordable Care Act. If denied, employees have the right to appeal within 30–60 days. The process involves submitting updated ID, proof of employment, and medical records if applicable. Employers must provide a clear explanation of the denial. Many find hiring a benefits advocate helpful to navigate complex appeals efficiently and increase success rates.
