ICD-10 Code L85.2 – Keratosis punctata (palmaris et plantaris) (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L85.2 – Keratosis punctata (palmaris et plantaris)
What it is
L85.2 identifies keratosis punctata of the palms and soles, a disorder marked by small, keratotic pits or papules on thick skin. It is a descriptive diagnosis for localized hyperkeratosis.
Clinical signs
Findings usually include multiple tiny, punctate, rough lesions on the palmar or plantar surfaces. Clinical features vary; refer to documentation if the record does not clearly describe the distribution or appearance.
When to use this code
Use L85.2 when the provider documents keratosis punctata specifically involving the palms, soles, or both. It fits charted cases where the diagnosis is established clinically and no more specific alternate condition is recorded.
If the note only says “hyperkeratosis” or “skin thickening” without this named condition, check documentation before coding. Code the documented diagnosis, not a presumed equivalent.
Do not use for
Do not use this code for diffuse calluses, nonspecific dry skin, or other keratotic disorders that are not documented as keratosis punctata. Check documentation if the site or diagnosis is unclear.
Coding tip
Look for the exact phrase “keratosis punctata (palmaris et plantaris)” or a clearly matching provider diagnosis before assigning L85.2.
