For federal workers suffering from chronic pain, finding noninvasive treatments that assist the healing journey is vital. A TENS unit (Transcutaneous Electrical Nerve Stimulation) is often considered to help control pain without drugs. If your OWCP claim is accepted, you may wonder whether a TENS unit is covered and how to use it properly. This article explains both so you can make informed choices.
A TENS unit is a small portable device that delivers low voltage electric pulses through electrodes placed on the skin. The pulses aim to reduce pain signals sent to the brain or stimulate release of endorphins, the body’s natural painkillers. People use TENS for back, knee, shoulder, or nerve pain. It is considered an adjunctive pain relief tool but not a standalone cure.
Under OWCP rules, TENS unit supplies must be billed under HCPCS code A4595 and are no longer billed as individual services. That includes electrodes, conductive gel, batteries, and the unit itself. However the device and supplies must be considered necessary to give relief or reduce disability. OWCP examines whether the prescription is medically justified and tied to your accepted injury.
If your DOL doctor believes a TENS unit is necessary for your pain control, they should document it clearly and submit a request to OWCP through your claims examiner. The request must show how TENS use is medically needed and how it will help your symptoms. Support your request with prior treatments tried, pain severity logs, and objective findings. Be prepared for review and potential additional information requests.
Always place the electrodes on clean, dry skin and avoid broken or irritated skin. Start with low intensity and gradually increase to a comfortable level. Never use intensity that creates a sharp or burning pain. Use it for brief sessions (for example 20 to 30 minutes) and monitor your skin for irritation. Do not place electrodes over the eyes, across the heart, or on your neck or chest without guidance. Always follow your treating DOL doctor’s instructions.
TENS units can offer pain relief without relying entirely on medications, helping to reduce side effects from long-term drug use. They can be used during flareups like sciatica flare ups to help you remain functional, allowing you to engage more actively in rehabilitation. Some patients report improved quality of life, better sleep, and more control over pain levels. While not everyone responds, when used properly and documented, it can support your recovery.
If OWCP denies your TENS request, you can pursue other approved therapies. Physical therapy, oral or injection pain medications, nerve blocks, and modalities like ultrasound or electrical stimulation (with different billing codes) may be considered. Work with your DOL doctor to explore these options. Keep medical documentation of treatments tried and outcomes to support later appeals or new requests.
A TENS unit may or may not be approved depending on your medical evidence, documentation, and claim status. To ensure that you will get approved with the appropriate medical equipment that you need for your treatment, seek help from federal injury doctors in Mississippi that can assist you with any paperwork you need to get your OWCP case approved.

Frequently Asked Questions
For most people, yes. But there are important cautions: don’t use a TENS unit if you have a pacemaker or implanted electronic device, epilepsy, are pregnant in certain areas, or have certain skin conditions. Always check with your healthcare provider first.
Sometimes you might get skin irritation, redness, soreness, or a tingling feeling. If settings are too high or pads are placed incorrectly, you might feel discomfort or muscle twitching.
Many people use it 1-3 times a day, for about 20–60 minutes per session. It’s best to follow the guidance of your physical therapist or doctor. Overuse or using it too long can reduce effectiveness or lead to skin issues.
Pads should go around or near the painful area, not over open wounds, swollen or infected skin, or areas with numbness. You shouldn’t put them on your neck, throat, eyes, or chest in a way that passes across the heart.
