What 97036 covers
This service covers therapeutic immersion in a Hubbard tank, a large tank used to treat one or more body areas with water. Physical therapists and other qualified therapy clinicians may use it during rehabilitation when tank-based hydrotherapy is part of the treatment plan, including care involving multiple extremities or a larger body area. The code represents the water modality, not active exercise performed in a pool or tank.
Report one unit for each 15 minutes of service, supported by documentation of the treatment provided and its duration. Distinguish this service from localized whirlpool treatment and from active aquatic exercise. Medicare treats it as a therapy service rather than separate professional and technical components, so it is not split with a professional-component modifier. Under the therapy multiple procedure payment reduction, practice expense is reduced for the second and later therapy units furnished on the same day.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

97036 billing questions
When should this code be chosen instead of whirlpool therapy?
Use this code for Hubbard tank treatment. Whirlpool therapy is a separate modality; select the code that matches the equipment and treatment actually provided.
How are units reported?
The code is reported in 15-minute units. Document the treatment duration to support the units billed.
Can active aquatic exercise be reported with this service?
This code represents the tank modality, while aquatic exercise is an active therapeutic procedure. Report both only when each distinct service was provided and documented.
Should modifier 26 be appended?
No. Medicare treats this as a therapy service, not as separate professional and technical components.
What happens to payment when multiple therapy units are billed on the same day?
Medicare reduces the practice expense for the second and later therapy units furnished that day under the therapy multiple procedure payment reduction.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
