About 97113: Aquatic therapeutic exercise, each 15 minutes
Report aquatic therapeutic exercise for direct, one-on-one treatment in a pool when water supports strengthening, range of motion, balance, or mobility goals.
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.

97113 billing questions
When should 97113 be reported instead of 97110?
Use 97113 when exercise is performed in a pool and the water is part of the therapeutic intervention. Use 97110 for land-based therapeutic exercise.
Can aquatic therapy be billed for a group class in the pool?
97113 requires direct one-on-one contact. For group-directed pool exercise provided to two or more patients simultaneously, report the untimed group therapy code 97150 instead.
How are units counted for 97113?
Count direct one-on-one treatment minutes. Under Medicare's 8-minute rule, 8 to 22 minutes supports one unit and 23 to 37 minutes supports two units when 97113 is the only timed therapy service; when multiple timed services are furnished, determine total units from their combined timed minutes and allocate units to the services performed.
Should gait or balance work done in the pool be coded separately as 97116 or 97112?
Water walking and balance exercises performed as part of aquatic therapy are included in 97113 for those minutes. Separate 97116 or 97112 units require distinct treatment time for the respective intervention.
What documentation supports medical necessity for aquatic rather than land therapy?
Document why the water environment supports treatment, such as pain or limited weight-bearing tolerance during land exercise. Record the exercises performed, direct treatment minutes, and their connection to the patient's goals.
Does the therapy reduction apply to every 97113 unit?
No. Medicare reduces the practice expense portion for second and later therapy units on the same day, including additional 97113 units; it does not reduce every unit solely because 97113 was reported.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
