1. CPT Code 97110 Description
CPT Code 97110 refers to Therapeutic Exercise, a widely used physical therapy (PT) and rehabilitation code. It involves exercises designed to improve strength, flexibility, endurance, range of motion (ROM), and overall functional mobility.
This code is commonly billed by physical therapists, occupational therapists, and chiropractors for patients recovering from injuries, surgeries, or chronic conditions such as arthritis, stroke, or musculoskeletal disorders.

2. What Is CPT Code 97110?

Sports injuries (e.g., ACL tears, tendonitis)
Example of 97110 Application:
A patient recovering from a total hip replacement may perform:
-
Seated leg presses (strengthening)
-
Hip abduction/adduction exercises (ROM improvement)
-
Stationary cycling (endurance building)
Each 15-minute block of supervised exercise can be billed under 97110.

4. CPT Code 97110 Billing Guidelines
To avoid claim denials, follow these billing rules:
A. Medical Necessity Documentation
-
Initial evaluation must justify the need for therapeutic exercise.
-
Progress notes should show measurable improvement (e.g., increased strength, reduced pain).
B. Time-Based Billing
-
8 minutes = 1 unit (Medicare’s 8-minute rule).
-
Multiple units can be billed if the session exceeds 23+ minutes.
C. Common Denial Reasons
-
Lack of functional goals in documentation.
-
Unbundling (billing 97110 with 97140 without separate justification).
-
Exceeding maximum allowed units per session.
5. What Is Procedure Code 97110?
Procedure Code 97110 is identical to CPT 97110—both refer to Therapeutic Exercise. Some electronic health records (EHR) systems may label it differently, but the billing structure remains the same.
6. CPT Code 97110 Reimbursement
Reimbursement depends on:
-
CMS (Medicare) Fee Schedule
-
Private Payer Contracts
-
State Medicaid Policies
Maximizing Reimbursement Tips:
✔ Use modifiers (e.g., -59 for distinct services).
✔ Combine with other codes (e.g., 97530 – Therapeutic Activities) if justified.
✔ Avoid duplicate billing (e.g., 97110 + 97112 for overlapping services).
7. CPT Code 97110 and 97140: Key Differences
| Factor | 97110 (Therapeutic Exercise) | 97140 (Manual Therapy) |
|---|---|---|
| Definition | Active patient participation | Passive therapist manipulation |
| Examples | Resistance bands, squats | Joint mobilization, massage |
| Billing Time | 15-min increments | 15-min increments |
| Can Be Combined? | Yes (if separately justified) | Yes (with modifier -59) |
Best Practice: Use 97110 + 97140 only if the treatments address different impairments (e.g., strength + joint stiffness).
8. Conclusion
CPT Code 97110 is essential for rehabilitative care, covering strength, flexibility, and mobility exercises. Proper documentation, adherence to billing rules, and understanding payer policies ensure optimal reimbursement. Combining it with 97140 (Manual Therapy) can enhance treatment efficacy when appropriately justified.
