Other melanin hyperpigmentation
ICD-10 L81.4 is a billable code used to indicate a diagnosis of other melanin hyperpigmentation.
L81.4 refers to 'Other melanin hyperpigmentation,' a dermatological condition characterized by an abnormal increase in melanin production in the skin, leading to darkened patches or spots. This condition can occur in various anatomical regions, including the face, arms, and other sun-exposed areas. Common clinical presentations include lentigines, post-inflammatory hyperpigmentation, and other localized or diffuse areas of increased pigmentation. The disease progression can vary, with some patients experiencing stable pigmentation while others may see changes in size or color over time. Diagnostic considerations include a thorough patient history, physical examination, and, if necessary, skin biopsy to rule out other conditions such as melanoma or other skin disorders. It is essential to differentiate L81.4 from other hyperpigmentation codes, such as L81.0 (melasma) and L81.1 (solar lentigines), to ensure accurate coding and treatment planning.

L81.4 encompasses various forms of melanin hyperpigmentation not classified elsewhere, including post-inflammatory hyperpigmentation, drug-induced pigmentation, and other less common forms. It is essential to evaluate the patient's history and clinical presentation to determine the specific type.
L81.4 should be used when the hyperpigmentation does not fit the criteria for other specific codes like L81.0 or L81.1. It is crucial to document the absence of other known causes of hyperpigmentation to justify the use of this code.
Documentation should include a detailed patient history, physical examination findings, and any relevant diagnostic tests. Photographic evidence may also be beneficial to illustrate the condition's extent and characteristics.
