Disseminated superficial actinic porokeratosis (DSAP)

This code represents a chronic, inherited skin disorder characterized by multiple, small, annular, hyperkeratotic lesions with a distinctive raised border and central atrophy. These lesions typically appear on sun-exposed areas of the skin, such as the extremities, shoulders, and back. DSAP is a variant of porokeratosis, distinguished by its widespread distribution and exacerbation by UV light exposure.

Use this code for patients diagnosed with disseminated superficial actinic porokeratosis. This diagnosis is typically made clinically based on the characteristic appearance of the lesions and their distribution. Documentation should clearly describe the presence of multiple, annular, hyperkeratotic lesions with central atrophy, particularly on sun-exposed skin, consistent with DSAP.

• Differentiate from other forms of porokeratosis (e.g., classic porokeratosis of Mibelli, linear porokeratosis) which have distinct ICD-10-CM codes.
• Ensure documentation specifies "disseminated superficial actinic" to support the specificity of this code.
• Consider coding for associated conditions, such as actinic keratosis, if present and documented.
