Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the L83 range.

Acanthosis Nigricans

A circumscribed melanosis consisting of a brown-pigmented, velvety verrucosity or fine papillomatosis appearing in the axillae and other body folds. It occurs in association with endocrine disorders, underlying malignancy, administration of certain drugs, or as in inherited disorder.

Hirsutism

A condition observed in WOMEN and CHILDREN when there is excess coarse body hair of an adult male distribution pattern, such as facial and chest areas.

About the L83 Code Range

ICD-10 code L83 is specifically used for identifying and documenting acanthosis nigricans, a skin condition characterized by dark, thickened patches commonly found in body folds and creases. This code helps distinguish this disorder from other skin conditions in medical records and billing.

Acanthosis nigricans often occurs in association with insulin resistance, as seen in type 2 diabetes, and can appear in various forms including drug-induced pigmentation and malignant variants. The code L83 covers a range of related presentations such as "insulin receptor defect," "diabetic dermopathy," and "drug-induced acanthosis nigricans," terms commonly used interchangeably in clinical settings. Including these synonyms aids medical coders in accurately assigning the correct ICD-10 code when patients present with related symptoms or underlying causes like extreme insulin resistance or genetic insulin signaling defects. This code also encompasses rarer syndromes linked to acanthosis nigricans, ensuring comprehensive classification in clinical documentation.
