Scoliosis (M41) ICD-10-CM
The M41 code range covers scoliosis with 65 ICD-10-CM diagnosis codes. 55 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- kyphoscoliosis
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- congenital scoliosis NOS Q67.5
- congenital scoliosis due to bony malformation Q76.3
- postural congenital scoliosis Q67.5
- kyphoscoliotic heart disease I27.1
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the M41 range.
Scoliosis
An appreciable lateral deviation in the normally straight vertical line of the spine. (Dorland, 27th ed)
About the M41 Code Range
ICD-10 code M41 covers all types of scoliosis, a condition where the spine curves abnormally sideways. This coding section is used to classify different forms of scoliosis, including infantile, juvenile, adolescent idiopathic, neuromuscular, thoracogenic, secondary, and other specified or unspecified types based on their cause or location on the spine.
The ICD-10 code for scoliosis helps specify the exact type and region affected, such as cervical, thoracic, lumbar, or lumbosacral areas. For example, M41.0 codes infantile idiopathic scoliosis, which includes synonyms like acquired scoliosis or idiopathic kyphoscoliosis, while M41.1 and M41.12 denote juvenile and adolescent idiopathic scoliosis, respectively. Codes like M41.4 address neuromuscular scoliosis, often associated with conditions like cerebral palsy or poliomyelitis. The detailed subcodes help medical coders accurately document scoliosis related to specific spine regions or causes, ensuring precise clinical and billing records. Using these detailed ICD-10 codes for scoliosis supports better tracking and treatment of spinal deformities across age groups and etiologies.
