ICD-10 Code L53.2 – Erythema marginatum (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L53.2 – Erythema marginatum
What it is
Erythema marginatum is a distinctive skin rash coded when documentation identifies this specific erythematous eruption. It is a descriptive diagnosis, so use it only when the record names it directly.
Clinical signs
Clinical features vary; refer to documentation. The rash is typically annular or serpiginous, with a pale center and a red, raised border.
When to use this code
Use L53.2 when the clinician documents erythema marginatum as the diagnosis or a confirmed finding. It may appear in notes describing a characteristic migratory rash, but you should code only what is explicitly stated. If the chart is nonspecific, check documentation.
Do not use for
Do not use this code for nonspecific erythema, hives, or other rashes without clear documentation of erythema marginatum. If the condition is only suspected, not confirmed, check documentation.
Coding tip
Match the code to the exact documented rash name; do not infer erythema marginatum from appearance alone.
