Other congenital malformations (Q80-Q89)

ICD-10 codes Q80–Q89 categorize a wide range of congenital malformations affecting skin, integument, breast, phakomatoses, malformation syndromes, and other body systems. These codes are used to precisely document birth defects and hereditary syndromes involving structural and functional abnormalities present from birth.

This range includes codes for specific skin disorders like congenital ichthyosis (Q80) with types such as Ichthyosis vulgaris and Lamellar ichthyosis, and epidermolysis bullosa types (Q81), which cause skin fragility. It also covers hereditary lymphedema (Q82.0), xeroderma pigmentosum (Q82.1) characterized by UV sensitivity, and ectodermal dysplasias (Q82.4) involving abnormalities in hair, nails, teeth, and sweat glands. Congenital breast malformations appear under Q83, while Q84 addresses various integumentary system defects including alopecia and nail abnormalities. The phakomatoses category (Q85) includes neurofibromatosis types 1 and 2 and tuberous sclerosis, known for benign tumors affecting skin and nervous tissue. The syndromes subdivision (Q86-Q87) documents malformation syndromes caused by exogenous factors and genetic syndromes like Prader-Willi syndrome (Q87.11) and Marfan syndrome (Q87.4), including manifestations in cardiovascular, skeletal, and ocular systems. Finally, Q89 captures miscellaneous congenital malformations such as asplenia and situs inversus.

These codes assist medical professionals and coders in identifying and recording a spectrum of complex congenital conditions, connecting common terms like “fetal alcohol syndrome,” “accessory nipple,” and “congenital alopecia” to specific ICD-10 codes ensuring accurate diagnosis and data tracking.
