Low level laser therapy

Coverage decision

L&I does not cover low level laser therapy for any condition due to the lack of evidence showing effectiveness.

Low level laser therapy (LLLT) is a light source treatment that generates light of a single wavelength. LLLT emits no heat, sound, or vibration. Instead of producing a thermal effect, LLLT may act via nonthermal or photochemical reactions in the cells, also referred to as photobiology or biostimulation. LLLT devices include the gallium arsenide (GaAs), gallium aluminum arsenide infrared semiconductor (GaAlAs), and helium neon (HeNe) lasers.

Athletic trainers, chiropractors, practitioners of alternative medicines, and physical therapists have used LLLT to treat a variety of disorders. Indications include carpal tunnel syndrome, joint disorders and tendinopathies, lateral and medial epicondylitis, osteoarthritis, low back pain, ankle sprains, venous ulcers, and decubitus ulcers.
