Whether you are a billing company specializing in Behavioral Health Practices Billing Texas Medicaid, or a practice that is dealing directly with TMHP and Medicaid Managed Care, reading up on the rules of TMHP can literally be the line between clean claims and never-ending denials. Texas providers will benefit from this guide, which really is a breakdown of coverage, coding, and compliance. Understanding Texas Medicaid Behavioral Health Billing Texas Medicaid covers behavioral health through Fee-for-Service and Managed Care, including psychiatric evaluation, psychotherapy, medication management, group/family therapy, and substance use disorder treatment. Most members today are enrolled in Managed Care. Flow: Patient → Eligibility → MCO Assignment → Authorization → Coding → Claim Submission → Payment. Texas Medicaid Managed Care Programs Behavioral health claims route through STAR, STAR+PLUS, STAR Kids, or STAR Health, each contracting with MCOs like Superior HealthPlan, Molina, Wellpoint (Amerigroup), UnitedHealthcare, and BCBSTX. Authorization rules and reimbursement can differ by MCO — even for identical services.

Prior Authorization & Documentation Higher levels of care (intensive outpatient, residential, some psychotherapy beyond initial sessions) typically require PA — timeframes and rules vary by MCO. The most common mistake is treating PA rules as identical across all MCOs. Documentation must support medical necessity, treatment plan, session time, progress notes, and provider signature. Talk to Billing Experts Common Claim Denials Denial Reason Fix Missing PA Service required authorization not obtained Verify PA rules per MCO before treatment Wrong MCO billed Claim sent to TMHP instead of assigned MCO Confirm MCO assignment at each visit Insufficient documentation Notes don’t support billed time Standardize progress note templates Telehealth Billing POS 02 generally applies to telehealth, POS 03 to school-based settings, with modifier 95 often required. Audio-only and telepsychiatry visits may have separate coverage rules by MCO. Compliance Requirements Behavioral health records fall under Texas HB 300 (stricter than HIPAA), federal HIPAA, and 42 CFR Part 2 for substance use disorder records. Best Practices ✔ Verify eligibility every visit ✔ Confirm PA requirements per MCO ✔ Document medical necessity and session time ✔ Code accurately to the correct specificity ✔ Audit denial trends regularly Why Practices Outsource Texas Medicaid Billing Managing MCO-specific rules alongside TMHP requirements takes time.

Talk To Our Team about your Texas Medicaid billing. Texas Medicaid behavioral health billing isn’t something a general medical billing team can pick up on the side — the rules genuinely differ by MCO, and getting them wrong means denied claims and delayed reimbursement. Our team stays current on Superior, Molina, Wellpoint, UnitedHealthcare, and BCBSTX’s individual authorization and documentation requirements, so your practice isn’t left guessing which rules apply to which patient. We also handle credentialing and enrollment alongside billing, so providers get set up correctly with each MCO from day one — reducing the authorization and payment delays that come from credentialing gaps. And because compliance in Texas means navigating HB 300 on top of HIPAA, we build that into our documentation and reporting processes rather than treating it as an afterthought.
