CPT Code 97034 | Contrast Baths

CPT 97034 is a code for contrast bath therapy, a treatment method involving alternating hot and cold water immersion with alleviating joint or muscle soreness, swelling, and inflammation. Each 15-minute session counts as one unit.


The CPT book defines CPT 97034 as: “Application of a modality to 1 or more areas; contrast baths, every 15 minutes.”


Contrast bath therapy, also referred to as hot/cold immersion therapy, is a highly effective treatment method utilized by healthcare providers to alleviate soreness, swelling, and inflammation in the joints or muscles.

This technique involves immersing the affected limb or joint in alternating hot and cold water, which causes the blood vessels to dilate and constrict.

This alternate dilation and constriction of the blood vessels lead to increased circulation in the damaged tissue, leading to a rapid recovery.

The therapy may be performed on one or multiple affected areas in a single session, with each 15-minute session counted as one unit.

It is a well-established therapy with a long history of success, and it has been proven to be an effective solution for a wide range of conditions.

It is also a relatively non-invasive procedure, making it a great alternative to more aggressive treatments such as surgery or injections.

The therapist begins by immersing the affected limb or joint in hot water, typically around 104°F, for three to five minutes.

This is followed by immersion in cold water, typically around 50°F, for one to three minutes.

The alternating hot and cold immersions are repeated for the duration of the session, with the therapist’s frequency and duration determined by the therapist based on the specific needs of the patient.
