    OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.

    Coverage Criteria

    Initial Coverage Criteria

    Covered when ALL of the following are met

    Primary diagnosis: Member has any mental health diagnosis from the current DSM or ICD as the primary diagnosis.

    Source: medical necessity criteria

    Assessment and individualized treatment plan (ITP): Services are based on a current comprehensive assessment and are included as interventions in the member's individualized treatment plan (ITP).

    Source: service requirements
