CARC Code 7
The maximum benefit for this time period has been exhausted.
What this denial means
When you see CARC code 7 on your Explanation of Benefits (EOB), it means your insurer has denied the claim with the following reason: the maximum benefit for this time period has been exhausted.
This code is one of the most common denial reasons in the CARC system and appears across both employer-sponsored and ACA marketplace plans. How you respond depends on whether the denial is a patient-side or provider-side issue.
Can you appeal this?
Yes — this denial is patient-appealable. If the service qualifies as an Essential Health Benefit under the ACA, annual and lifetime dollar limits are prohibited under 42 U.S.C. § 300gg-11; argue the cap is unenforceable. For ERISA plans, challenge whether the capped service category matches the plan documents and whether mental health parity under MHPAEA applies.
Applicable federal regulations:
ERISA plans (employer-sponsored)
- ERISA § 503
- 29 CFR § 2560.503-1(h)
ACA plans (marketplace / individual)
- PHS Act § 2719
- 45 CFR § 147.136(b)
- 45 CFR § 147.136(c)
- 45 CFR § 147.136(d)
Your insurer's legal team is bound by these regulations. An appeal letter that cites them directly demands a specific, documented response.
