CO-119: Lifetime Benefit Maximum Reached

CO (Contractual Obligation)

What is CO-119?

CO-119 is a Contractual Obligation code indicating the patient has reached the lifetime benefit maximum for this service category. Unlike CO-39 (annual maximum), CO-119 means the lifetime cap has been exhausted.

Why Does CO-119 Occur?

  1. Patient has reached the lifetime dollar maximum for the benefit category.
  2. Lifetime visit limit exhausted (e.g., lifetime maximum for transplant-related services).
  3. Plan's lifetime cap for a specific condition has been met.

How to Fix CO-119 Denials

  1. Verify the patient's lifetime accumulators on the payer portal.
  2. If the lifetime maximum is incorrect, appeal with documentation of prior claims and accurate accumulator totals.
  3. Inform the patient of their options: self-pay, financial assistance, or alternative coverage.
  4. Check whether the ACA lifetime maximum prohibition applies to the patient's plan (grandfathered plans may still have lifetime caps).
