Transcutaneous Electrical Nerve Stimulation (TENS) is a trusted, clinically-proven, noninvasive therapy used for the management of, and relief from, chronic (long-term) intractable pain and post-surgical and post-trauma acute pain.

Indications for TENS

  • Relief of chronic (long-term) intractable pain
  • Reduce Muscle Guarding
  • Relief of post-surgical acute pain
  • Relief of post-trauma acute pain


To ensure the likelihood of reimbursement, justification of medical necessity for TENS must be substantiated; the following documentation should be provided to both CriterionMed and the patient’s insurance provider

  • Letter of Medical Necessity (prescription, diagnosis codes, ABN, etc.)
  • Treatment Records should include (if applicable):
    1. Therapy History – including records relative to treatment
    2. Presenting Symptoms and Complaints
    3. Diagnosis of Condition(s)
    4. Lab Test Results
    5. X-Rays/MRIs
    6. Patient Follow-Up Progress (i.e. successful use, compliance, etc.)
    7. Recommended Plan of Care

Ultimately, the clinician must exercise his or her own judgement when documenting treatment plans assessment.

Please contact Criterion if any of the above forms are required. A Criterion Representative will contact you directly if additional information regarding claims submission is required.

Additional Billing Codes

  • E0730 – Billing Code for the TENS unit itself.
  • 97002 – Physical therapy re-evaluation
  • 64550 – Application of surface (Transcutaneous) Neurostimulator – TENS/NMS. This is commonly referred to as “fitting.” The fitting process entails diagnosing, and instructing the patient as to where to place electrodes (box in area of treatment) and inform them of warning, etc.
  • 97032 – Application of a modality to one or more areas; electrical stimulation (manual), each 8-20 minutes (per area) [Modality used to apply electrical current to a specific area. Attended electrical stimulation is also referred to as manual stimulation Attended stimulation calls for the application of stimulation for shorter or more specific time frames and at varying degrees of current.] Example: If patient has two areas of pain (i.e. cervical and lumbar) you would spend 8-20 minutes on each area and bill for your time spent on each area.
  • 97014 – Electrical Stimulation (unattended) – (one or more areas) [The application of electrical stimulation to specific areas. The term unattended means that the patient is positioned and the appropriate type of stimulation is applied to an area, over a specific time period. Nerve and muscle stimulation can be useful in any disorder in which the patient has lost or never had adequate voluntary control over skeletal muscle. Until such time as the patient achieves useful control, it is most helpful to use this type of stimulation along with other interventions such as passive exercise.
