Disseminated superficial actinic porokeratosis (DSAP)
ICD-10 L56.5 is a billable code used to indicate a diagnosis of disseminated superficial actinic porokeratosis (dsap).
Disseminated superficial actinic porokeratosis (DSAP) is a benign skin condition characterized by the development of small, superficial keratotic lesions that typically appear on sun-exposed areas of the skin, particularly the forearms and lower legs. The lesions are often described as having a raised, keratotic border with a central atrophic area, resembling a ring. DSAP is thought to be related to chronic sun exposure and is more common in individuals with fair skin. The condition usually manifests in middle-aged adults and may progress slowly over time, with new lesions appearing while existing ones may persist. Diagnosis is primarily clinical, supported by a thorough history of sun exposure and the characteristic appearance of the lesions. In some cases, a biopsy may be performed to rule out other conditions such as squamous cell carcinoma or actinic keratosis. Management typically involves sun protection measures and, in some cases, topical therapies such as 5-fluorouracil or cryotherapy to reduce lesion visibility.

L56.5 specifically covers disseminated superficial actinic porokeratosis, which is characterized by multiple superficial keratotic lesions primarily due to sun exposure. It is distinct from other actinic conditions such as actinic keratosis or porokeratosis of Mibelli.
L56.5 should be used when the clinical presentation aligns with disseminated superficial actinic porokeratosis, particularly when lesions are widespread and superficial, differentiating it from localized or more severe forms of actinic keratosis.
Documentation should include a detailed clinical examination noting the appearance and distribution of lesions, patient history of sun exposure, and any treatments attempted. A biopsy report may also be beneficial to confirm the diagnosis.
