Disorders of skin appendages (L60-L75)

ICD-10 codes L60-L75 cover disorders affecting skin appendages, including nails, hair, and sweat glands. These codes specify conditions such as diverse nail abnormalities, various forms of hair loss, and sweat gland disorders, helping to precisely capture clinical diagnoses.

This range includes detailed codes for nail disorders (L60-L62) like ingrowing nails, onycholysis (nail separation), nail dystrophy, and yellow nail syndrome. For instance, paronychia due to ingrown nails is coded under L60.0. Hair loss codes (L63-L66) classify alopecia areata types including totalis and universalis, androgenic alopecia (male and female pattern baldness coded in L64), and scarring hair loss or cicatricial alopecia. Syndromes such as alopecia mucinosa and drug-induced hair loss are also included. The chapter further details follicular disorders (L73) like pseudofolliculitis barbae and hidradenitis suppurativa. Sweat gland issues (L74-L75) span conditions such as miliaria (heat rash), anhidrosis (lack of sweating), hyperhidrosis (excessive sweating), and apocrine sweat disorders including bromhidrosis and chromhidrosis. Each condition is linked with synonyms to aid coders, such as “prickly heat” for miliaria rubra (L74.0) or “female pattern alopecia” for androgenic alopecia variants. These codes support accurate classification of skin appendage diseases crucial for treatment and insurance processes.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
