    Clinical & Coding Specifications

    Clinical Context

    A middle-aged patient presents to a physical medicine and rehabilitation clinic with persistent lumbar radiculopathy and chronic low back pain after conservative care. The clinician selects a two-channel interferential current stimulator to deliver transcutaneous electrical stimulation to bilateral paraspinal and gluteal regions to reduce pain and improve function. The clinical workflow includes: initial evaluation and documentation of pain location, intensity, prior treatments, and goals; placement of two-channel electrodes over target muscle groups or dermatomes; device parameter selection (carrier frequency, beat frequency, intensity) and a typical 15–30 minute supervised treatment; monitoring for patient tolerance and skin integrity during application; documentation of time, settings, electrode placement, and response; and scheduling of follow-up sessions or transition to home-use modalities if appropriate. Typical sites of service are outpatient physical therapy clinics, physician office-based therapy suites, and ambulatory rehabilitation centers. Typical patient scenarios also include postoperative rehabilitation for joint procedures, chronic shoulder pain with myofascial components, and neuropathic pain adjunctive treatment.
