Does Humana Cover TENS / Electrotherapy? (2026 Guide)

How TENS Works for Joint Pain

Transcutaneous Electrical Nerve Stimulation (TENS) delivers low-voltage electrical impulses through electrodes placed on the skin near the painful joint. It works by:

1. Gate control theory: Electrical signals block pain signals from reaching the brain
2. Endorphin release: Stimulates natural pain-relieving chemicals
3. Reduced inflammation: Some evidence of anti-inflammatory effects at specific frequencies

Types of Electrotherapy

Getting Insurance to Cover Your TENS Unit

The key difference is prescription vs. over-the-counter. A TENS unit prescribed by your doctor and obtained through an approved DME supplier is a covered benefit. The same device purchased at Walgreens or Amazon is not.

Steps to get coverage:

1. Ask your doctor for a TENS unit prescription with diagnosis codes
2. Use a DME supplier enrolled in your insurance network
3. Keep documentation of medical necessity
4. For Medicare: use a CMS-enrolled DME supplier (check Medicare.gov supplier directory)

Evidence for TENS in Arthritis

TENS has moderate evidence for short-term OA pain relief. A 2019 Cochrane review found TENS provides clinically meaningful pain reduction for knee OA when used consistently. Best results occur with daily use of 20-40 minutes per session at appropriate intensity.
