This section covers 37 ICD-10-CM codes (L49-L54) for urticaria and erythema, including exfoliation due to erythematous conditions according to extent of body surface involved, urticaria, and erythema multiforme. 33 of these are billable codes usable on a claim; the rest are non-billable header categories that require a more specific child code.
