Highmark Blue Cross Blue Shield PPO plans may cover a partial hospitalization program (PHP) for addiction treatment, but exact benefits depend on the member’s specific plan. Trinity Behavioral Health accepts Highmark BCBS when the policy provides applicable coverage. Highmark’s 2026 behavioral-health authorization update added specific PHP codes to its prior authorization list beginning March 1, 2026.
Before PHP begins, verify your Highmark BCBS PPO PHP benefits.
Is PHP automatically covered?
No. Coverage depends on active eligibility, plan benefits, network status, medical necessity, and authorization requirements.
Can prior authorization be required?
Yes. Highmark announced that certain PHP codes require prior authorization effective March 1, 2026. Exact requirements still depend on the member’s product and benefit plan.
How does medical necessity affect PHP?
Highmark’s commercial medical policy describes PHP as a structured, medically supervised outpatient level of care and provides clinical conditions under which it may be considered medically necessary.
