ICD-10 Code L41.8 – Other parapsoriasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L41.8 – Other parapsoriasis
What it is
L41.8 identifies other forms of parapsoriasis, a group of uncommon chronic scaly skin disorders. Use it when the record names parapsoriasis but does not fit a more specific subtype.
Clinical signs
Findings usually include persistent, patchy, scaly plaques or thin patches on the skin. Clinical features vary; refer to documentation, especially when the note distinguishes this from psoriasis or another dermatosis.
When to use this code
Use this code when the clinician documents other parapsoriasis, atypical parapsoriasis, or a parapsoriasis type not otherwise specified. It is also appropriate when the subtype is unclear but the diagnosis is clearly documented. Check documentation if the note suggests a different inflammatory or premalignant skin condition.
Do not use for
Do not use it for plaque psoriasis, pityriasis rosea, or nonspecific dermatitis. If the chart names a different exact diagnosis, code that condition instead.
Coding tip
Code L41.8 only when the provider explicitly documents parapsoriasis; vague descriptions of scaly rash need clarification.
