The ICD-10-CM code L51.9 might also be used to specify conditions or terms like coccidioidomycosis with erythema multiforme, drug-induced erythema multiforme, erythema multiforme, erythema multiforme co-occurrent with ulcer of oral mucous membrane, erythema multiforme due to malignancy , erythema multiforme minor, etc.
Unspecified diagnosis codes like L51.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
