Hypertrichosis (L68)
Hypertrichosis codes in ICD-10-CM cover a range of conditions characterized by abnormal hair growth patterns. These codes, beginning with L68, are used to classify various forms of excessive hair growth, from generalized to localized and specific subtypes like hirsutism.
The primary code, L68, represents hypertrichosis broadly, while more detailed codes such as L68.0 specify hirsutism, commonly known as excessive hair growth in women, linked to conditions like insulin receptor defects or drug use. Other codes like L68.1 define acquired forms such as acquired hypertrichosis lanuginosa, often associated with anorexia nervosa. L68.2 addresses localized hypertrichosis, describing excessive hair growth confined to specific regions like the face or limbs. Additional categories include L68.3 for polytrichia and L68.8 for other specified types, covering rare syndromes and non-androgenic hypertrichosis variants. When the hair growth pattern isn't clearly classified, L68.9 is used for unspecified hypertrichosis, including drug-induced or malnutrition-related hair changes. Understanding these codes assists medical coders and healthcare professionals in accurately documenting diverse presentations of abnormal hair growth within the ICD-10 coding system.
Instructional Notations
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- excess hair
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.
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.
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. It is the result of elevated ANDROGENS from the OVARIES, the ADRENAL GLANDS, or exogenous sources. The concept does not include HYPERTRICHOSIS, which is an androgen-independent excessive hair growth.
Hypertrichosis
Excessive hair growth at inappropriate locations, such as on the extremities, the head, and the back. It is caused by genetic or acquired factors, and is an androgen-independent process. This concept does not include HIRSUTISM which is an androgen-dependent excess hair growth in WOMEN and CHILDREN.
Microstomia
A congenital defect in which the mouth is unusually small. (Dorland, 27th ed)
