Medicare coverage. The Medicare TENS policy does not name this area; coverage depends on your plan and your clinician's documentation. As of the LCD revision effective January 1, 2024, it covers TENS for "chronic, intractable pain or acute post-operative pain" when criteria are met.
How are TENS pads placed for shoulder, arm or hand pain?
Pads go on clean skin near the painful area, and your clinician should show you the exact spots. The NHS says: “Place the sticky pads onto clean skin, near the painful parts of your body. Leave a gap between the pads.” The University of Iowa Health Care page includes an illustration of sensor placement on the elbow and shoulder. It is an example from one health system.
| Question | What the sources say |
|---|---|
| Where do pads go? | Near the painful area, with a gap between pads (NHS) |
| Near the chest? | Do not use on both sides of the chest or trunk at the same time (University of Iowa) |
| With a pacemaker? | Do not use TENS (NHS, University of Iowa) |
| On the neck? | The NHS says not to use TENS on your neck |
Our guide to pad placement lists more rules. The guide on TENS for neck, shoulder and headache covers the shoulder in more detail.
Why do shoulder pads need extra care?
Shoulder pads can sit close to the chest and neck, and both areas have limits. The University of Iowa Health Care page lists “Both sides of the chest or trunk at the same time” among places not to use TENS. The NHS says: “Do not use TENS on your neck, mouth or eyes” and “Do not use TENS on your chest and back at the same time.”
Ask your clinician to mark safe areas for you. Do not move a pad across to a place that is not on your clinician’s plan. Turn the unit off before you move or remove pads, as the University of Iowa page advises. See our post on where not to put TENS pads.
Can I use a TENS unit with a pacemaker?
No. 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: “Do not use TENS if you have: A cardiac pacemaker or defibrillator.” It also lists “Any implanted metallic or electronic device.”
Read the glossary entries on cardiac pacemaker and implanted medical device. Our post on TENS units and pacemakers explains more. Tell every clinician about any implanted device.
What about carpal tunnel syndrome and hand pain?
Pad placement for hand or wrist pain depends on the cause, so ask your clinician where your pads should go. The glossary entry on carpal tunnel syndrome defines the term. Your clinician needs to find the cause of hand pain before any device is chosen.
If your clinician orders a trial, ask where the pads may go and for how long. Follow your clinician’s instructions and your device’s instructions. Do not use TENS on skin that is broken, irritated, infected or numb, as the NHS says.
What does Medicare say about this area?
The Medicare TENS policy, local coverage determination (LCD) L33802, does not name arm, shoulder or hand pain. As of the revision effective January 1, 2024, it says “A TENS is covered for the treatment of beneficiaries with chronic, intractable pain or acute post-operative pain when one of the following coverage criteria, I or II, are met.”
The policy also says “A TENS unit will be denied as not reasonable and necessary for acute pain (less than three months duration) other than for post-operative pain.” It lists headache as not reasonable and necessary. Coverage depends on your plan and your clinician’s documentation. Other plans differ, so check with your plan. Our insurance coverage guide explains the usual steps.
What can help alongside a TENS unit?
Your clinician may suggest posture changes, stretching or therapy. Our blog has general reading for the neck and shoulders: the epidemic of text neck, how to correct posture problems and health benefits of stretching regularly. These posts do not replace a visit with your clinician.
The University of Iowa Health Care page says TENS helps most during activities such as walking, doing chores, or exercise. Ask your clinician which activities are right for your arm, shoulder or hand.
Who else should not use a TENS unit?
The NHS says not to use TENS on irritated, broken, infected or numb areas of skin, while you sleep, in the bath or shower, or when driving or using tools or machinery. Follow your clinician’s instructions and your device’s instructions. Read our TENS unit safety guide.

Questions people ask
Where do TENS pads go for shoulder pain?
Your clinician or physical therapist should show you. The NHS says to place pads near the painful parts of your body with a gap between them. The University of Iowa page includes an elbow and shoulder illustration, but it is an example. Never place pads where your clinician says not to.
Can I use a TENS unit on my shoulder if I have a pacemaker?
No. The NHS says not to use TENS if you have a pacemaker. The University of Iowa Health Care page says not to use it with a cardiac pacemaker or defibrillator, or any implanted metallic or electronic device. Ask your clinician before any placement near your chest.
Does Medicare cover a TENS unit for arm, shoulder or hand pain?
The Medicare TENS policy (LCD L33802) does not name arm, shoulder or hand pain. It covers TENS for chronic, intractable pain or acute post-operative pain when criteria are met. Coverage depends on your plan and your clinician's documentation. Check with your plan.
Can I use a TENS unit for carpal tunnel syndrome?
Pad placement for carpal tunnel syndrome depends on the cause. See your clinician for a diagnosis. If your clinician orders a trial, ask where the pads may go and which areas are off limits.
