Billing and Coding: Low frequency, non-contact, non-thermal ultrasound

CPT 97610 (low-frequency, non-contact, non-thermal ultrasound, e.g., MIST) is described as a wound care therapy used to atomize liquid and deliver ultrasound to the wound bed. When CPT 97610 is used to treat the same wound as active wound care management or wound debridement codes (97597, 97598, 97602, 97605, 97606), it is included in payment and not separately reimbursed; the policy does not specify additional documentation or frequency limits.

"Low-frequency, non-contact, non-thermal ultrasound (CPT 97610) is used for wound care to deliver continuous low-frequency ultrasonic energy and to atomize and deliver liquid to the wound bed."
