ICD-10 Code L90.3 – Atrophoderma of Pasini and Pierini (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L90.3 – Atrophoderma of Pasini and Pierini
What it is
L90.3 identifies atrophoderma of Pasini and Pierini, a localized skin atrophy disorder. It is used when documentation specifically names this condition.
Clinical signs
Typical findings include well-defined, depressed patches of skin with thinning and a “cliff-drop” border. Clinical features vary; refer to documentation.
When to use this code
Use L90.3 when the provider documents atrophoderma of Pasini and Pierini as the diagnosis. Code it for confirmed localized dermal atrophy described by name in the record. If the note only says skin thinning or atrophy without this specific diagnosis, check documentation.
Do not use for
Do not use this code for nonspecific skin atrophy, scars, or other localized depressions unless the condition is explicitly identified as atrophoderma of Pasini and Pierini.
Coding tip
Confirm the exact diagnosis wording in the assessment, not just the physical description.
