Other congenital malformations of integument (Q84)
ICD-10 code Q84 covers various rare congenital malformations of the skin, hair, and nails. These codes specify distinct inherited or developmental defects affecting the integumentary system, including alopecia, nail abnormalities, and other skin-related malformations present from birth.
The category includes Q84.0 for congenital alopecia, which encompasses conditions such as congenital localized or generalized alopecia and related syndromes like Marie Unna syndrome and ichthyosis-associated alopecia. Q84.1 and Q84.2 describe congenital hair disorders, including unique patterns like pili torti and woolly hair, as well as hypertrichosis and uncombable hair syndrome. Nail abnormalities are detailed under Q84.3 (anonychia), Q84.4 (congenital leukonychia), Q84.5 (enlarged or hypertrophic nails), and Q84.6 (other nail malformations), covering conditions such as pachyonychia congenita and various dystrophies. Q84.8Q84.9 is used when a congenital integument malformation is present but not specifically classified.
These ICD-10 codes provide precise classification for coding and tracking uncommon congenital integument defects, helping clinicians and coders identify and document detailed conditions like congenital alopecia, nail dystrophies, and hair shaft abnormalities accurately.

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.
