M41 is a non-billable ICD-10-CM category code for scoliosis, so it cannot be submitted on claims. Use a more specific code from this category instead, such as M41.00, M41.02, M41.03, and M41.04.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to M41: its own notes plus those printed at Chapter 13. A note printed at a category, block or chapter applies to every code under it.

Includes

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

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

  • M40 Kyphosis and lordosis
    kyphoscoliosis (M41.-)

Excludes2 1

These codes carry an Excludes2 note naming M41: its condition is not part of those codes, and both may be reported when the patient has both.

Clinical InformationClinical

  • Scoliosis

    an appreciable lateral deviation in the normally straight vertical line of the spine. (dorland, 27th ed)

Patient EducationClinical

Scoliosis

Scoliosis causes a sideways curve of your backbone, or spine. These curves are often S- or C-shaped. Scoliosis is most common in late childhood and the early teens, when children grow fast. Girls are more likely to have it than boys. It can run in families. Symptoms include leaning to one side and having uneven shoulders and hips.

Questions About M41Overview

What is the ICD-10 code for scoliosis?

M41 is the ICD-10-CM category for scoliosis, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is M41 (Scoliosis) a billable code?

No. This is a category header that groups the codes for scoliosis, and headers cannot be submitted on claims. Claims for scoliosis need a more specific code from this category, such as M41.00, M41.02, and M41.03.

Can M41 be reported with Q67.5?

Not as a rule. The Excludes1 note on M41 lists "congenital scoliosis NOS (Q67.5)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
