CPT 97610 Low‑Frequency Ultrasound Reimbursement | OpenPayer

Summary & Overview

CPT 97610: Low‑Frequency Ultrasound Therapy for Wound Healing

CPT code 97610 designates provider‑administered low‑frequency ultrasound therapy intended to promote wound healing. The service is used in wound care management for patients with chronic or nonhealing wounds and is clinically significant because it represents a noninvasive adjunctive therapy aimed at reducing healing time and complications. Nationally, uptake is shaped by payer coverage policies, evidence standards for efficacy, and site‑of‑service patterns.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coverage considerations and common claim practices for these payers, benchmark utilization notes where available, and the clinical context in which the therapy is applied. The publication outlines how the procedure is billed, typical settings of care, and operational aspects relevant to revenue cycle teams and clinicians managing wound services.

This analysis provides practical reference material: a clinical description of the service, typical sites of care, payer coverage landscape, and topics for further policy review. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 97610 describes the use of a low‑frequency ultrasound device applied by a provider to promote wound healing. The procedure is a therapeutic wound treatment that uses mechanical energy from low‑frequency ultrasound to debride, stimulate tissue, and enhance healing in chronic or acute wounds.

Service type: Therapeutic wound care using low‑frequency ultrasound
Typical site of service: Outpatient wound care clinic, physician office, or outpatient hospital setting

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult with a chronic, nonhealing lower-extremity wound such as a diabetic foot ulcer or venous stasis ulcer that has failed standard care (debridement, infection control, offloading/compression, and advanced dressings) over a period of weeks to months. The provider evaluates the wound in the outpatient wound clinic or skilled nursing facility, documents wound size, depth, presence of necrotic tissue, exudate, surrounding skin condition, and prior treatments. After confirmation that the wound is appropriate for adjunctive therapy, the clinician uses a low-frequency therapeutic ultrasound device applied directly to the wound bed and periwound tissues to attempt to promote healing. Typical workflow: wound assessment and measurement, wound cleansing and selective debridement as needed, documentation of indications and prior therapies, selection of 97610 for low-frequency ultrasound treatment, application of the device per manufacturer instructions, post-treatment dressing, and scheduling of follow-up visits to monitor response. Typical sites of service are outpatient wound clinics, physician offices, hospital outpatient departments, and skilled nursing facilities. The patient is often seen serially (multiple sessions over days to weeks) with progress notes documenting changes in wound dimensions and response to therapy.
