Denial code CO-119: Benefit maximum reached
The patient has used up the plan’s limit for this benefit — visits, units, dollars, or occurrences — for the period.
Benefit maximum for this time period or occurrence has been reached.
What CO-119 actually means
The plan caps this benefit and the cap has been exhausted. Therapy visit limits, chiropractic caps, DME allowances, and annual dollar maximums all produce CO-119. The claim is correctly adjudicated; the question is whether an exception process exists and whether the patient understood the limit before the visits continued. Where a plan permits medically necessary extensions, an appeal with documentation can succeed.
Why this denial happens
- The annual or per-period visit limit was reached.
- A dollar maximum for the benefit category was exhausted.
- Units delivered exceeded the plan’s allowance for the occurrence.
- Prior visits at another provider counted toward the same shared limit.
How to resolve a CO-119 denial
- Confirm the limit and the count the payer has applied, including visits at other providers.
- Appeal with medical-necessity documentation where the plan permits extensions beyond the cap.
- Where the cap is absolute, transfer the balance to the patient with a signed waiver on file.
How to prevent it
- Track remaining benefit units per patient and warn before the cap is hit, not after.
- Tell the patient in writing when they approach a visit or dollar limit.
