CPT Code 97150: Group Therapeutic Procedures

CMS 2026 Update — CPT 97150

Group therapeutic procedures (CPT 97150) remain covered when documentation clearly demonstrates group-based goals and appropriate patient selection. CMS reiterates the need for individualized assessment and documentation of each participant’s response for CY2026.

What is CPT 97150?

CPT 97150 represents Group Therapeutic Procedures — a code used for billing therapeutic procedures conducted in a group setting, where the therapist is not providing one-on-one attention to any single patient. This code is applicable when the focus is on group dynamics and collective therapeutic goals.

Typical uses: This code is used in settings such as physical therapy clinics, rehabilitation centers, and wellness programs where patients benefit from shared therapeutic activities.

In short: CPT 97150 = Group therapy sessions.

When to Use CPT 97150 (and When Not To)

Use 97150 for billing therapeutic procedures conducted in a group setting where the therapist is facilitating group activities rather than providing individualized attention.

• Report when multiple patients are engaged in similar therapeutic activities simultaneously.
• Ensure that the group therapy is part of a structured treatment plan with documented goals.

Do not use for individual therapy sessions or when the therapist provides one-on-one attention to a single patient during the session.

Clinical Examples

• Group balance training for fall prevention → 97150
• Individual gait training session → 97116

Medicare & Payer Reimbursement Rates

Medicare reimbursement for CPT 97150 is set through the CMS Physician Fee Schedule (MPFS), which CMS updates every year — the CY2026 final rule set the conversion factor at $33.5675 for qualifying APM participants and $33.4009 for all other providers, both increases over CY2025. The exact non-facility payment also depends on your locality’s Geographic Practice Cost Index, and commercial payers negotiate their own contracted rates rather than publishing one national figure. Because of this, the table below describes how each payer typically structures reimbursement rather than fixed dollar amounts — always confirm the current rate on your MAC’s published fee schedule or in your payer contract before billing.

Documentation Guidelines (CMS & MIPS Compliant)

Thorough documentation demonstrates medical necessity, skilled care, and functional intent. Include:

1. Functional goal (e.g., “Patient will improve balance through group exercises”).
2. Activity description — explicit tasks practiced, environment, and level of assistance.
3. Clinical rationale — why this activity addresses the patient’s deficit.
4. Time documentation — minutes per activity and total minutes (apply the 8-minute rule for units).
5. Patient response — tolerance, cues required, measurable progress.

Sample SOAP Note (De-identified)

S: Patient reports feeling more confident in group settings and enjoys the social interaction.
O: Participated in 30-minute group session focusing on balance and coordination exercises.
A: Demonstrated improved balance with fewer cues needed; able to perform tasks with moderate assistance.
P: Continue with group therapy twice weekly to enhance balance and social engagement.
  

Modifiers & Coding Tips

Claim tip: Ensure that group therapy is clearly documented as distinct from individual therapy to avoid denials.

Common Denials & How to Prevent Them

1. Lack of documentation — Fix: Ensure detailed notes on group activities and individual progress.
2. Incorrect modifier use — Fix: Apply modifiers correctly to indicate distinct services.
3. Medical necessity not established — Fix: Clearly document the therapeutic goals and outcomes for each patient.

Audit trigger: Repeated billing of group therapy without clear documentation of group dynamics and individual progress.

Region & Local Payer Notes

In Arizona, providers should be aware that Noridian MAC oversees Medicare claims. Ensure compliance with local policies and verify reimbursement rates with regional payers. Group therapy services may be subject to specific state regulations, so consult with local Medicaid offices for guidance.
