Other acquired deformities of musculoskeletal system and connective tissue (M95) ICD-10-CM
The M95 code range covers other acquired deformities of musculoskeletal system and connective tissue with 12 ICD-10-CM diagnosis codes. 10 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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 M95 range.
Craniosynostoses
Premature closure of one or more CRANIAL SUTURES. It often results in plagiocephaly. Craniosynostoses that involve multiple sutures are sometimes associated with congenital syndromes such as ACROCEPHALOSYNDACTYLIA; and CRANIOFACIAL DYSOSTOSIS.
Muscle Rigidity
Continuous involuntary sustained muscle contraction which is often a manifestation of BASAL GANGLIA DISEASES. When an affected muscle is passively stretched, the degree of resistance remains constant regardless of the rate at which the muscle is stretched. This feature helps to distinguish rigidity from MUSCLE SPASTICITY. (From Adams et al., Principles of Neurology, 6th ed, p73)
Pectus Carinatum
A developmental anomaly characterized by abnormal anterior protrusion of the STERNUM and adjacent COSTAL CARTILAGE.
Plagiocephaly
The condition characterized by uneven or irregular shape of the head often in parallelogram shape with a flat spot on the back or one side of the head. It can either result from the premature CRANIAL SUTURE closure (CRANIOSYNOSTOSIS) or from external forces (NONSYNOSTOTIC PLAGIOCEPHALY).
Plagiocephaly, Nonsynostotic
A deformity of the SKULL that is not due to bone fusion (SYNOSTOSIS), such as craniosynostoses, and is characterized by an asymmetric skull and face. It is observed with an increased frequency in INFANTS after the adoption of supine sleeping recommendations to prevent SUDDEN INFANT DEATH SYNDROME.
About the M95 Code Range
ICD-10 code M95 covers various other acquired deformities of the musculoskeletal system and connective tissue. These codes identify specific deformities that develop after birth and affect bones, cartilage, or soft tissues in different body areas.
This section includes detailed codes such as M95.0 for acquired deformity of the nose, capturing conditions like saddle nose and nasal hump, and the M95.1 series for different forms of cauliflower ear, a common acquired deformity of the ear’s pinna. The codes also address deformities of the head (M95.2), neck (M95.3), chest and ribs (M95.4) including pectus excavatum and barrel chest, pelvis (M95.5), and other musculoskeletal deformities not specified elsewhere (M95.8). When the site or details are unclear, M95.9 provides a code for unspecified acquired musculoskeletal deformities. Medical coders use these codes to report acquired structural changes like deformities from injuries, postural abnormalities, or surgical sequelae accurately, ensuring clear communication in clinical documentation and billing.
Questions About This Page
How many billable codes are in the M95 range?
Of the 12 codes in this range, 10 are billable and valid for claim submission from October 1, 2025 through September 30, 2026. Category header codes group them but cannot be reported on claims.
What does the M95 range classify?
The range classifies other acquired deformities of musculoskeletal system and connective tissue. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
