What 97034 covers
Contrast bath therapy alternates immersion of a body area in warm and cool water as a therapeutic modality. Physical and occupational therapists commonly provide it in outpatient rehabilitation settings, often for a hand, foot, or other extremity. The treatment differs from a hot or cold pack because the area is immersed in alternating-temperature water rather than treated with a pack.
Report one unit for each 15-minute increment supported by the treatment record. Documentation should identify the treated area, the contrast-bath intervention, the time provided, and its therapeutic purpose and response. This is a therapy service; a professional component modifier does not apply. Under the therapy multiple procedure payment reduction, CMS reduces practice expense 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.

97034 billing questions
How is this different from hot or cold pack therapy?
Contrast baths involve alternating warm and cool water immersion. Code 97010 describes hot or cold pack treatment, not alternating-temperature immersion.
How many units should be reported?
The code is reported in 15-minute units. Document the treatment time and the area treated to support the units billed.
Can a professional component modifier be appended?
No. CMS identifies this as a therapy service for which the professional component modifier does not apply.
How does the therapy multiple procedure payment reduction affect this service?
CMS reduces practice expense for the second and later therapy units furnished on the same day. The reduction applies to practice expense, not the work component.
When would 97022 be a better fit?
Use 97022 for whirlpool therapy involving agitated water. Code 97034 is for alternating warm and cool water immersion.
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.
