Benefit Maximum / Lifetime Maximum Reached
The patient's plan only covers a set amount/number of this service per period (CO-119) or ever (CO-35/CO-149), and that limit has already been used up.
Guided troubleshooter available for this denial
Answer a few questions to reach the correct disposition. No patient or claim identifiers requested.
In plain language
The patient's plan only covers a set amount/number of this service per period (CO-119) or ever (CO-35/CO-149), and that limit has already been used up.
Start here
Confirm the plan's specific benefit maximum for the service category and the current accumulator status.
Who resolves it
Billing/Follow-Up
Who prevents it
Registration/Scheduling — benefit-maximum check before scheduling elective/repeat services.
How to resolve this denial, step by step
- 1
Confirm the plan's specific benefit maximum for the service category and the current accumulator status.
- 2
Verify the CPT/HCPCS billed is correctly categorized under that benefit.
- 3
If mis-categorized, correct and resubmit.
- 4
If the maximum has genuinely been reached, confirm whether the payer's accumulator reflects all prior payer-paid services accurately, and dispute if there is a documented discrepancy.
- 5
If accurate, determine patient-responsibility eligibility per the plan document.
- 6
Document the benefit-maximum verification.
Then choose the correct disposition
Corrected claim
only for a benefit-category coding error.
Payer follow-up
when the accumulator appears inaccurate.
Patient responsibility
appropriate once the benefit maximum is confirmed accurate and the plan/contract permits patient billing for services beyond the maximum.
Stop and escalate when
- Suspected accumulator discrepancy between the payer's system and documented prior claims; patient disputes the benefit-maximum determination.
What Needs to Be Corrected
- Claim correction: Rarely applicable; verify the code billed actually falls in the maxed-out benefit category (a coding error placing the wrong category could be corrected).
- Upstream correction: Registration/Scheduling should check benefit accumulators before scheduling elective or repeat services subject to a known plan maximum.
Do Not Do This
- Do not recode the service to a different, uncapped benefit category unless that category genuinely and accurately describes the service performed.
- Do not bill the patient before confirming the accumulator is accurate.
