Other acquired deformities of musculoskeletal system and connective tissue (M95)
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.

Instructional Notations
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
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
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.
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.
