Exfoliatn d/t erythemat cond w 90 or more pct of body surfc

This code signifies widespread skin peeling or shedding (exfoliation) that results from an underlying erythematous (reddened) skin condition. It specifically applies when 90% or more of the patient's total body surface area is affected by this extensive exfoliation.

Use this code for patients presenting with severe, generalized desquamation secondary to an inflammatory skin process, such as erythroderma or exfoliative dermatitis. Documentation must clearly indicate the extensive body surface area involvement (90% or greater) and the erythematous nature of the underlying condition.

• Ensure documentation explicitly states "90% or more" body surface area involvement; otherwise, a less specific code may be appropriate.
• This code describes the exfoliation due to the erythematous condition; a separate code for the underlying specific erythematous condition (e.g., psoriasis, drug eruption) should be sequenced first.
• Do not use for localized exfoliation or conditions where erythema is not the primary cause of the peeling.
