ICD-10 Code L53.1 – Erythema annulare centrifugum (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L53.1 – Erythema annulare centrifugum
What it is
L53.1 identifies erythema annulare centrifugum, a skin eruption that forms expanding ring-shaped or arc-shaped red patches. You use this code when the diagnosis is documented as this specific reactive dermatosis.
Clinical signs
Typical findings include annular or polycyclic erythematous lesions with central clearing and outward spread. Clinical features vary; refer to documentation.
When to use this code
Use L53.1 when the provider documents erythema annulare centrifugum by name, including suspected or confirmed cases recorded in the chart. It may also fit when the note describes classic annular, migrating plaques and the diagnosis is stated clearly. Check documentation if the rash is nonspecific.
Do not use for
Do not use this code for other annular rashes, fungal infections, or unspecified erythema unless the provider names erythema annulare centrifugum. If the diagnosis is unclear, check documentation.
Coding tip
Code the condition only when the provider links the rash to erythema annulare centrifugum, not just to “ring-shaped rash.”
