Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 97113 covers

Aquatic therapy uses exercise in a pool, where buoyancy reduces joint loading and water provides resistance. Physical therapists, occupational therapists, and supervised therapy assistants provide it to patients who have difficulty tolerating land-based activity, including those recovering from joint replacement or managing osteoarthritis or neurologic weakness. Treatment may include water walking, resisted limb movements, balance drills, and flexibility exercises. The clinician provides direct one-on-one contact, whether working from the pool deck or in the water.

Report 97113 in 15-minute units based on direct treatment time, not the patient's total time in the pool. Documentation should identify the exercises, direct treatment minutes, and why the aquatic environment supports the plan of care. For Medicare, identify the therapy discipline with GP or GO, as appropriate, and determine units using the total timed therapy minutes furnished that day. This therapy service has no separate professional component for modifier 26. Under Medicare's therapy multiple procedure payment reduction, the practice expense portion is reduced for the second and later therapy units on the same day, including additional 97113 units.
