Coverage Summary

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

This policy defines medical necessity criteria and minimum program requirements for community-based Partial Hospitalization Programs (PHP) and Intensive Outpatient Programs (IOP) and takes the stance covered with criteria — services are covered when the policy's specified clinical and program requirements are met. PHP and IOP are intermediate-level outpatient behavioral health services delivered by multidisciplinary teams operating under physician oversight, and benefits are subject to the member's subscriber certificate in effect at the time of service.

Partial Hospitalization Programs are structured, time-limited, medically supervised outpatient programs delivering intensive care while the individual resides at home. Intensive Outpatient Programs are planned, structured short-term services for individuals needing more monitoring than typical outpatient care, with participants residing at home and attending sessions multiple times per week.

Provider Actions & Requirements

Prior Authorization

Authorization Manager use for initial notification/authorization

Providers must use Authorization Manager to submit initial notification or authorization requests; commercial member requests must meet InterQual Behavioral Health criteria and medical policy guidelines; Medicare Advantage requests must adhere to CMS guidelines.

Documentation Required

Documentation requirements at admission and ongoing

Document psychosocial assessment (within the first program day or one day prior), psychiatric evaluation (within the first program day), drug screens and relevant labs on admission and as clinically indicated, daily clinical assessments during attendance, weekly psychiatric/medication evaluations for PHP (or as needed for IOP), and safety planning accessible to members and families.

Billing Rule

Report services with up-to-date codes and provider identifiers

Enter the servicing provider's NPI (individual) not the billing group, and enter the facility's NPI for the service location; report services using current procedure, revenue, and diagnosis codes and modifiers where applicable.

Denial Risk

Potential denial for services not meeting intensity or setting requirements

Services may be denied if they are provided in less intensive settings, are non-medical only, are court-ordered, custodial, or beyond the period necessary for treatment, or if the program does not meet minimum staffing, accreditation, or licensure criteria.

Background & Evidence

Partial Hospitalization Programs (PHP) and Intensive Outpatient Programs (IOP) are intermediate levels of outpatient behavioral health care intended to treat mental health and substance use disorders that significantly interfere with daily functioning. Both levels are delivered by licensed, accredited facilities or agencies using individualized care plans and multidisciplinary teams under physician supervision. PHPs provide more intensive, structured care (typically 20+ hours/week) while IOPs provide planned, structured short-term services with fewer hours per week. These programs include assessments, psychotherapy (individual, group, family), medication management, care coordination, and crisis services as clinically indicated. Coverage and authorization are subject to the member's subscriber certificate and must meet the policy's documented clinical and program requirements.
