Keratosis punctata (palmaris et plantaris)
ICD-10 L85.2 is a billable code used to indicate a diagnosis of keratosis punctata (palmaris et plantaris).
Keratosis punctata (palmaris et plantaris) is a benign dermatological condition characterized by the presence of small, keratinized papules on the palms of the hands and the soles of the feet. These lesions are typically firm, yellowish, and may vary in size, often resembling tiny corns or calluses. The condition is thought to arise from localized hyperkeratosis due to friction, pressure, or irritation, leading to the formation of these punctate keratotic lesions. The anatomy involved primarily includes the epidermis, where keratinocytes proliferate excessively, resulting in the characteristic appearance. Disease progression is generally slow, and while keratosis punctata is not associated with significant morbidity, it can cause discomfort or pain, particularly in weight-bearing areas. Diagnostic considerations include a thorough clinical examination and, if necessary, a biopsy to rule out other skin disorders such as plantar warts or other forms of keratosis. The condition is often self-limiting, but treatment may involve topical keratolytics or mechanical debridement to alleviate symptoms.

L85.2 specifically covers keratosis punctata occurring on the palms and soles. It is characterized by small, hard, keratinized lesions and is distinct from other keratotic conditions such as keratosis pilaris or actinic keratosis.
L85.2 should be used when the lesions are specifically located on the palms and soles and exhibit the punctate keratotic appearance. It is important to differentiate it from other keratotic conditions that may not be localized to these areas.
Documentation should include a detailed clinical examination noting the location, size, and appearance of the lesions, as well as any symptoms reported by the patient. Treatment plans and responses should also be documented to support the diagnosis.
