CO-119 — Benefit Maximum Reached

CO-119 means the patient has hit the maximum visits, days, or dollars for the benefit. For mental health services, benefit maximums are the most direct form of MHPAEA parity violation — if a plan covers unlimited outpatient medical visits but caps therapy at 30 sessions, that is a per-se MHPAEA violation under 29 CFR § 2590.712(c). Request the payer's comparative analysis document and document the comparable medical/surgical benefit limit.
