What should patients know about the diagnostic process?
Diagnosis of Erythema Multiforme is typically clinical, based on the classic appearance of "target" lesions on the skin. Because Erythema Multiforme can be triggered by medications or underlying infections, your physician may perform a skin biopsy or blood work to rule out other dermatological conditions. Understanding your specific ICD-10 code can help you better communicate your history to specialists.
