Chiropractic ICD-10-CM codes

Medicare covers chiropractic manipulation only for subluxation, so claims must lead with an M99.0 segmental and somatic dysfunction code matched to the treated region: M99.01 cervical, M99.02 thoracic, M99.03 lumbar, M99.04 sacral, M99.05 pelvic. The region of the M99.0 code must correspond to the regions counted in the CMT procedure code, and mismatches are a routine denial reason.

Pair the dysfunction code with a secondary diagnosis that establishes medical necessity: cervicalgia (M54.2), low back pain (M54.50, or M54.59 for other specified), lumbago with sciatica (M54.41 right, M54.42 left), radiculopathy (M54.12 cervical, M54.16 lumbar), or cervicogenic-type headache (G44.209, or R51.9 when unspecified). Sciatica alone uses M54.30 to M54.32.

Acute trauma cases add chapter 19 sprain and strain codes with the required 7th character: S13.4XXA (cervical sprain, the whiplash code), S16.1XXA (cervical muscle strain), S33.5XXA (lumbar sprain), and S39.012A (lumbar strain). Use A while the condition is under active treatment and D once care shifts to the healing phase. Degenerative findings that explain chronic cases include M47.812 and M47.816 (spondylosis without myelopathy, cervical and lumbar), M50.30 and M51.26 for disc disorders, and M48.061 and M48.062 for lumbar stenosis.
