M41.03 — Infantile idiopathic scoliosis, cervicothoracic region
M41.03 is a billable, specific ICD-10-CM code for infantile idiopathic scoliosis, cervicothoracic region. It is valid for submission on a claim.
Excludes1 inherited from the categories above M41.03
These are not written on M41.03, but they bind it: a note on a category applies to every code beneath it. Billing M41.03 with anything listed here is a denial.
Excludes2 inherited from the categories above M41.03
Also inherited, and the opposite of Excludes1: these conditions are not part of M41.03, but a patient can have both, so you may code both.
Other codes that can never be billed with M41.03
These codes carry an Excludes1 note pointing at M41.03. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M41.03 alone.
- M40Kyphosis and lordosis
Risk adjustment
M41.03 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.
Medicare coverage
M41.03 is named in 16 Medicare coverage policies — 9 listing it as supporting medical necessity, and 7 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How M41.03 is indexed
