Acupuncture for Chronic Low Back Pain

How does acupuncture help chronic low back pain? Acupuncture alleviates pain by stimulating nerve endings to release natural painkillers like endorphins, reducing inflammation through vagus nerve activation, enhancing blood flow for tissue repair, and shifting the nervous system from a stress response to a restorative state.

What is the difference between acupuncture and dry needling?

Both acupuncture and dry needling use thin needles, but they differ in method and coverage. Acupuncture relies on Traditional Chinese Medicine to influence energy flow (Qi) through acupoints, while dry needling focuses on treating muscle trigger points to relieve pain. Licensed acupuncturists provide acupuncture services, while physical therapists deliver dry needling treatments.

For billing purposes, Medicare and some commercial payers reimburse acupuncture only under strict conditions. Additionally, Medicare does not cover dry needling, and insurers frequently deny claims even when providers bill CPT codes 20560 or 20561. Clear documentation must distinguish between the two services to prevent denials, particularly when providers perform both during the same session.
