Medicare coverage. As of the LCD revision effective January 1, 2024, the Medicare TENS policy (L33802) lists headache, and temporomandibular joint (TMJ) pain, as conditions for which TENS therapy "is not considered to be reasonable and necessary." Other plans set their own rules; check with your plan.
Does Medicare cover a TENS unit for headache?
No. The Medicare TENS policy, local coverage determination (LCD) L33802, lists headache among the conditions for which TENS is not considered reasonable and necessary. The text below is from the revision effective for services performed on or after January 1, 2024.
The policy says: “Examples of conditions for which TENS therapy is not considered to be reasonable and necessary are (not all-inclusive): headache visceral abdominal pain pelvic pain temporomandibular joint (TMJ) pain.” The list is not complete, and other plans set their own rules. Medicare Advantage, Medicaid, VA, workers’ compensation and commercial plans may differ, so check with your plan.

Our guide on TENS for neck, shoulder and headache covers this in more detail.
Where must TENS pads not go?
Two safety pages name places on the head and neck where TENS should not be used. Their wording differs, so read each one.
The NHS says: “Do not use TENS on your neck, mouth or eyes.” The University of Iowa Health Care page lists, under “Do not use TENS on:”, these items: “Any part of your head or face” and “Any part of your throat.”
The NHS wording says “neck” without limits. The University of Iowa wording says “throat.” They do not say the same thing. Do not guess which parts of the neck are allowed. Ask your clinician or physical therapist to mark safe areas for you. Our post on where not to put TENS pads lists more places.
Can a TENS unit be used for neck pain at all?
The University of Iowa Health Care page lists “Back and neck pain” among the types of chronic pain for which a TENS “may be used.” Its page also shows an illustration of sensor placement on the neck and back. That does not mean any neck area is safe. The same page says not to use TENS on any part of your throat, head or face.
The NHS, which says “Do not use TENS on your neck, mouth or eyes,” is stricter. Because the two pages differ, the safe choice is to ask your clinician before any placement near your neck. Our pad placement guide explains how to read placement advice.
What causes neck pain, and what can help besides a TENS unit?
Our blog covers neck and posture topics in plain terms: the epidemic of text neck, how to correct posture problems and long-term effects of bad posture. These posts are general reading, and they do not replace a visit with your clinician. Read the glossary entry on text neck.
For other options, see our guide to pain management without opioids. Ask your doctor before you try any new device or exercise for head or neck pain.
What safety rules apply to everyone?
The NHS says: “Do not use TENS if: you have epilepsy; you have a pacemaker; you’re pregnant, unless your doctor or midwife tells you to.” The University of Iowa Health Care page says to stop using TENS and talk with your doctor if you have skin irritation, headache, dizziness or nausea.
Follow your clinician’s instructions and your device’s instructions. Do not use TENS while you sleep, drive or use machinery. See our TENS unit safety guide. Learn the term contraindication in the glossary.
When should I see a clinician first?
See a clinician before you use a TENS unit if you are not sure what causes your pain. The NHS says: “If you’re not sure what’s causing your pain, see a healthcare professional before using a TENS machine.” Head and neck pain can have many causes, and a TENS unit will not find them.
