Chloasma
ICD-10 L81.1 is a billable code used to indicate a diagnosis of chloasma.
Chloasma, also known as melasma, is a common skin condition characterized by the appearance of brown or gray-brown patches on the skin, primarily on the face. It is most prevalent in women, particularly during pregnancy or with the use of oral contraceptives, due to hormonal changes that stimulate melanin production. The condition typically affects areas exposed to sunlight, such as the cheeks, forehead, and upper lip. The pathophysiology involves an increase in melanocyte activity, leading to hyperpigmentation. Diagnosis is primarily clinical, based on the characteristic appearance of the lesions, although a Wood's lamp examination may be used to differentiate between epidermal and dermal pigmentation. Disease progression can vary; while some cases resolve spontaneously, others may persist or worsen with sun exposure or hormonal fluctuations. Treatment options include topical agents like hydroquinone, tretinoin, and sunscreen, as well as procedural interventions such as chemical peels or laser therapy. However, recurrence is common, necessitating ongoing management and preventive measures.

L81.1 specifically covers chloasma or melasma, which is primarily associated with hormonal changes, sun exposure, and certain medications. It does not include other forms of hyperpigmentation or skin discoloration.
L81.1 should be used when the clinical presentation is consistent with chloasma, particularly in patients with a history of hormonal changes or sun exposure. It should not be used for other hyperpigmentation disorders without clear differentiation.
Documentation should include a detailed clinical history, examination findings, and any relevant hormonal assessments. Photographic evidence may also support the diagnosis and treatment plan.
