Denial code 35 means: The payer says the patient has reached the lifetime maximum dollar amount or service limit that the plan will pay for this benefit.
Why it happens: A patient typically sees this after long-term or high-cost treatment when the cumulative amount the plan agreed to pay over the patient's lifetime has been exhausted.
Is it appealable? Yes. Denials like this are frequently overturned when the appeal supplies the missing element and cites the plan's own rules. We do not publish a percentage for this category because we will not show a number we cannot back.
What to send: the missing element for this code, a short appeal letter citing the plan's claims-procedure rules, and any clinical support.
Note: code 35 may appear on your remittance with a group-code prefix such as PR-35 (patient responsibility) or CO-35 (contractual obligation). The denial reason is the same.
Expert analysis: how this denial is overturned
A benefit-maximum denial means the plan says you have reached a limit for this benefit, such as a visit cap or a dollar or occurrence maximum for the period. The critical step is to test whether the limit is lawful and correctly counted. Verify the count against your actual utilization, and check whether the limit conflicts with protections such as mental health parity, which can make certain quantitative limits impermissible. The denial is an adverse benefit determination, so the full-and-fair-review standard of 29 CFR 2560.503-1(h)(1) applies, and you may request the exact limit and counting method under 29 CFR 2560.503-1(g)(1)(v). You generally have at least 180 days to appeal (29 CFR 2560.503-1(h)(3)(i)), and parity-based disputes can be eligible for external review under 45 CFR 147.136. Honest odds: these reverse when the count is wrong or the limit is unenforceable under applicable parity protections.
