Running group therapy in Texas is amazing for patient outcomes, but the billing side can get messy fast. Medicaid rules shift, private insurers play by their own guidelines, and one small coding slip can cost your practice thousands.
Providers across the state are losing money every month simply because they don’t understand how Texas-specific billing guidelines actually work.
If you’re running a practice in Dallas, Austin, Houston, or anywhere in between, you can’t afford to guess your way through CPT codes, session limits, or reimbursement rules.
To stay competitive, you need a clear roadmap for group therapy billing in Texas. We break it down step by step so you can remain compliant, maximize reimbursements, and ensure you’re paid for every minute of care you provide.
Group Therapy Billing Rules in Texas
Texas works within federal guidelines for Medicare and Medicaid, but individual Managed Care Organizations (MCOs) have their own rules. Here are the core rules that are mandatory for group therapy in Texas:
- Group therapy must be clinically therapeutic, prescribed, and address a diagnosed medical or behavioral condition.
- A licensed therapist must be physically present and actively engaged throughout the entire session. One-on-one contact with each participant is not required, but the therapist’s active participation is mandatory.
- Each participant must have a separate note documenting goals, interventions, and progress.
- Providers may only bill for participants who actually attended the session.
- Prior authorization may be required for recurring group therapy sessions, unlisted procedure codes, or when therapy exceeds four units per day.
- For CRS programs, group therapy is limited to a maximum of 10 participants. For other Medicaid behavioral health groups, limits vary by MCO.
- Use CPT 90853 for behavioral health group therapy, while PT/OT/ST have their own group codes (CPT 97150).
- Maintain treatment plans, session notes, and attendance logs for audits and follow HIPAA privacy standards.
- Patients cannot be balance-billed for covered services, and medical debt collection must comply with Texas and federal law.
- A prescribing provider’s written prescription for group therapy must be in the record.
- Group therapy must be performed by or under the supervision of a licensed therapist.
- Each client must have an individualized treatment plan with frequency, duration, goals, and measurable outcomes.
- Documentation must include start and stop times, group setting/location, number of clients present, therapist signature, techniques used, and progress toward goals.
CPT Codes Used for Group Therapy
Common CPT codes used for group therapy in Texas are:
CPT 90853 – Group Psychotherapy
CPT 90853 is used for regular group therapy sessions where a therapist works with several patients at the same time, helping them cope with mental health issues, build skills, and support each other.
Important Note: CPT 90849 (Multiple-Family Group Psychotherapy) is NOT covered by Texas Medicaid. Only CPT 90853 is reimbursed for behavioral health group therapy in Texas. Providers should not bill 90849 to Texas Medicaid.
CPT 97150 – Therapeutic Procedure, Group (PT/OT/ST)
Texas Medicaid uses the same group therapy code (97150) for all ages, but the policy wording differs slightly. For clients 20 and younger, Medicaid states that providers can bill 97150, meaning the service is allowed when medically necessary.
For clients 21 and older, providers should bill 97150, which signals that this is the expected and proper code for adult group physical or occupational therapy. The difference is mostly in wording; both age groups use the same code, but adults follow a more directive billing requirement.

Group Therapy Billing Guideline: Texas Providers
Billing group therapy in Texas comes with its own set of Medicaid and insurance rules, CPT codes, and documentation requirements.
Step 1: Verify Therapy Type & Eligibility
Make sure your session qualifies as group therapy for two or more clients receiving treatment simultaneously. It must be therapeutic, prescribed, and medically necessary. Recreational or purely educational groups will not be reimbursed.
Step 2: Ensure Licensed Therapist Attendance
A licensed therapist must be in the room and actively leading the session. Constant physical presence and active participation are both required. For telehealth, verify payer coverage before scheduling virtual sessions.
Step 3: Prepare Individualized Treatment Plans
Each participant needs their own treatment plan with goals, interventions, and measurable outcomes. Even in a group setting, plans should reflect individualized progress to meet billing and medical necessity requirements.
Step 4: Select Proper CPT Codes & Modifiers
- Use 90853 for behavioral health group therapy
- Use 97150 for PT/OT/ST group therapy
- Use modifier 59 only when billing both individual psychotherapy and group therapy as separate sessions on the same day
- Use modifier 95 for telehealth sessions only if the payer allows reimbursement with the correct Place of Service (POS) codes
- Apply other discipline-specific modifiers only if required by your specific payer
Step 5: Document Thoroughly
Keep clear records: session start/stop times, location, number of participants, techniques used, therapist signature, and progress toward each client’s goals. Good documentation protects your claims and supports audits.
Step 6: Submit Claims & Follow Payer Rules
Submit claims electronically whenever possible. Include CPT codes, modifiers, and prior authorizations if required. Bill primary insurance first, track outcomes, and audit your documentation to avoid denials.
How to Maximize Revenue from Group Therapy Sessions in Texas
Group therapy typically pays less per person than individual therapy. The following elements are most important for maximizing revenue:
- Ensure Medical Necessity: Only bill for sessions that are therapeutic and medically necessary, supported by documented treatment plans. Each participant must have individualized goals and progress notes with start/stop times, treatment techniques, and outcomes to prevent claim denials.
- Review Your Contracts: Examine insurance contracts to identify reimbursement rates for CPT 90853 (behavioral/mental health) or 97150 (PT/OT/ST). Use this information to structure groups efficiently and determine whether to continue or renegotiate sessions.
- Maintain Accurate Attendance Records: Bill only for participants who actually attended. Clearly define and document attendance consistently to prevent billing errors.
- Batch Your Billing by Payer: When groups include clients with multiple insurers, submit claims by payer rather than by individual client. This streamlines processing and ensures adherence to each payer’s specific rules.
- Use Proper CPT Codes: Use 90853 for behavioral or mental health group therapy. Use 97150 for PT/OT/ST groups, reporting one unit per patient per session. Note that CPT 97150 is limited to one unit per session per client, and combined therapy services may not exceed 4 units per day in certain Texas programs.
- Apply Required Modifiers: Use modifier 95 for telehealth sessions only if the payer allows reimbursement with the correct POS codes. Verify discipline-specific modifier requirements with your payer before submitting claims. Append modifier 59 when billing both individual and group therapy sessions on the same day.
- Prior Authorization: Obtain authorization from the MCO before starting recurring sessions. Clearly explain clinical necessity, emphasizing that group therapy offers peer support and social learning not available in individual sessions.
- Understand Your Group Composition: Verify whether payers reimburse for your specific group type, such as trauma-focused or occupational therapy. Some insurers restrict reimbursement based on diagnosis or therapeutic modality.
- Optimize Group Size: Maximize the number of participants within program limits without compromising therapy quality. Verify group size limits with your specific MCO.
- Consider a Hybrid Model: Offer both insurance-based and private-pay groups. Insurance groups maintain accessibility, while private-pay groups allow clinical flexibility and simpler billing, diversifying revenue streams.
- Track Outcomes and Progress: Measure and document each participant’s progress consistently to justify ongoing therapy and support higher reimbursement.
- Leverage Telehealth When Appropriate: Telehealth can increase attendance and access. Ensure proper modifiers and POS codes are used only if the payer reimburses group therapy via telehealth.
- Audit and Review Regularly: Conduct internal audits to identify documentation gaps, coding errors, or missed billing opportunities, and correct issues promptly to maximize revenue while remaining compliant.
Medicaid Insurance for Group Therapy in Texas
Texas Medicaid operates through Managed Care Organizations (MCOs) rather than a single state program. Each MCO has different rates and policies.
Medicaid Rules for Group Therapy:
- Must be clinically necessary, prescribed, and supervised by a licensed therapist in constant attendance.
- Individualized treatment plans and thorough documentation are required.
- CRS programs limit group size to 10; verify limits with other MCOs.
- CPT 90853 is billed once per day per patient; use modifier 59 only when billing a separate individual psychotherapy session on the same day.
- CPT 97150: Billed one unit per patient per session. Combined PT/OT therapy is limited to 4 units per day in SHARS programs; verify limits with other programs.
- Prior authorization may be required for recurring sessions to contact your MCO before initiating recurring group therapy.
- For CRS programs, one hour of individual therapy or two hours of group therapy counts as one hour toward a tier.

Private Insurance for Group Therapy in Texas
Private insurance often follows CPT guidelines for group therapy, but coverage may vary by payer, diagnosis, therapy modality, and session type.
Private Insurance Rules for Group Therapy:
- CPT 90853 for behavioral health group therapy; CPT 97150 for PT, OT, or speech therapy groups
- Documentation must include individualized treatment goals, interventions, and participant progress
- Group size, session duration, and prior authorization requirements vary by insurer
- Modifiers such as 95 for telehealth or discipline-specific codes may be required; verify requirements before submitting
- Each participant should be billed separately, and attendance must be documented
- Private insurance may reimburse only for clinically necessary sessions; recreational or educational groups are not covered
- Maintain accurate records to prevent claim denials
Reimbursement Rates for Group Therapy Billing in Texas
Reimbursement rates for CPT 90853 (group therapy) vary depending on payer contracts, provider credentials, and geographic location. Nationally, commercial and private insurance reimbursements typically range from $30 to $65 per participant per session.
While specific Texas data is limited, available benchmarks suggest a reasonable estimate for Texas providers falls in the range of $30 to $50 per participant per session. Actual reimbursement varies significantly by MCO, contract terms, group size, and network status. Verify rates directly with your contracted MCO, as reimbursement may differ from these estimates.
