Pustulosis palmaris et plantaris

This code represents a chronic, sterile inflammatory skin condition characterized by recurrent pustules on the palms of the hands and soles of the feet. It is a distinct form of psoriasis, often associated with smoking and thyroid disorders, and can cause significant discomfort and functional impairment.

Use this code when documentation clearly indicates a diagnosis of pustulosis palmaris et plantaris. This diagnosis is typically made based on clinical presentation, often confirmed by biopsy showing sterile pustules and psoriasiform changes. It should be used for both initial diagnoses and subsequent encounters for management of this specific condition.

• Ensure the documentation specifies "palmaris et plantaris" to differentiate from other forms of pustular psoriasis.
• Do not confuse with other localized pustular conditions, such as dyshidrotic eczema or bacterial infections, which would require different codes.
• Consider co-morbidities like psoriasis vulgaris (L40.0) or thyroid disease when present, and code them separately.
