What Is an Annual Limit?
An annual limit (also called an annual cap or annual maximum benefit) is the maximum dollar amount a health plan will pay for covered services in a single plan year.
ACA and Annual Limits
The Affordable Care Act prohibits annual dollar limits on essential health benefits for most health plans. This was one of the most significant consumer protections introduced by the ACA — before 2010, many plans capped coverage at $1–2 million per year, leaving seriously ill patients without coverage.
💡 For ACA-compliant plans, there is no annual dollar limit on covered essential health benefits. Your insurer cannot stop paying for covered care because you've used "too much" in a year.
When Annual Limits Can Still Apply
- Grandfathered plans (from before 2010) may still have annual limits
- Short-term health plans are not ACA-compliant and may have annual limits
- Some supplemental plans (vision, dental, critical illness) may have annual maximums
- Non-essential health benefits may have limits even in ACA plans
