Is M41 a billable ICD-10-CM code?

No. M41 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does M41 sit in the tabular list?

Diseases of the musculoskeletal system and connective tissue (M00-M99), in the block Deforming dorsopathies (M40-M43).

What cannot be coded together with M41?

M41 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

M41

M41 — Scoliosis

Non-billable headerICD-10-CM

M41 is a non-billable header ICD-10-CM code for scoliosis. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

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

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

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

Includes

Conditions this code covers.

kyphoscoliosis

Other codes that can never be billed with M41

These codes carry an Excludes1 note pointing at M41. 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 alone.

M40Kyphosis and lordosis
Q67.5Congenital deformity of spine

Risk adjustment

M41 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.

Code to one of these instead M41

8 child codes. Green means billable.
