Electrical Stimulation for Chronic Wounds

Coverage decision

L&I or self-insurer covers electrical stimulation for specific wound indications with prior authorization.

Background

Electrical stimulation passes electric currents through a wound to accelerate wound healing via angiogenesis promotion, collagen synthesis and epithelial cell migration.

In this technique, one electrode is place on the skin near the wound and the other electrode is applied to saline-moistened guaze over the wound. As a conductive medium, saline allows the electric current to pass through the wound.

Four classes of devices are used and differentiated by type of current:

  1. Low-intensity direct current (LIDC).
  2. High voltage pulsed current (HVPC).
  3. Alternative current (AC).
  4. Transcutaneous electrical nerve stimulation (TENS).
Covered indications
  • Stage III and IV pressure ulcers.
  • Arterial ulcers.
  • Diabetic ulcers.
  • Venous stasis ulcers.
Prior authorization criteria

Prior authorization is required when electrical stimulation for chronic wounds is provided on an outpatient basis.

This technique will be authorized if the wound has not improved following 30 days of standard wound therapy. In addition to electrical stimulation, standard wound care must continue.

Criterion for continuing treatment beyond 30 days

A licensed medical personnel must provide documentation of wound measurements that show improvement has occured within the past 30 days.

Billing codes
HCPCS CodeDescription
G0281Electrical stimulation, (unattended), to 1 or more areas, for chronic Stage III and Stage IV pressure ulcers, arterial ulcers, diabetic ulcers, and venous stasis ulcers not demonstrating measurable signs of healing after 30 days of conventional care, as part of a therapy plan of care.
