M41.129

M41.129 — Adolescent idiopathic scoliosis, site unspecified

Billable / specific codeICD-10-CM

Excludes1 inherited from the categories above M41.129

Written on M41 — Scoliosis

congenital scoliosis NOS (Q67.5)
congenital scoliosis due to bony malformation (Q76.3)
postural congenital scoliosis (Q67.5)
kyphoscoliotic heart disease (I27.1)

Excludes2 inherited from the categories above M41.129

Also inherited, and the opposite of Excludes1: these conditions are not part of M41.129, but a patient can have both, so you may code both.

Written on M41 — Scoliosis

postprocedural scoliosis (M96.89)
postradiation scoliosis (M96.5)

Other codes that can never be billed with M41.129

These codes carry an Excludes1 note pointing at M41.129. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M41.129 alone.

M40Kyphosis and lordosis

Risk adjustment

M41.129 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
