ICD-10 Code L49.6 – Exfoliation due to erythematous condition involving 60-69 percent of body surface (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L49.6 – Exfoliation due to erythematous condition involving 60-69 percent of body surface
What it is
This code identifies exfoliation, or widespread skin peeling, caused by an erythematous condition affecting 60% to 69% of body surface. Use it when documentation links the desquamation to a red, inflammatory skin disorder.
Clinical signs
Expect diffuse erythema with skin scaling or peeling over a large body area. Clinical features vary; refer to documentation for the underlying erythematous condition and the stated percentage of body surface involved.
When to use this code
Use this code when the record clearly states exfoliation due to an erythematous condition and specifies 60% to 69% body surface involvement. It fits cases where the extent is documented more precisely than a general rash or dermatitis. If the percentage or cause is not recorded, check documentation before assigning this code.
Do not use for
Do not use this code for exfoliation without a documented erythematous cause or when body surface involvement falls outside 60% to 69%. Do not guess the percentage from appearance alone.
Coding tip
Confirm both the cause and the exact body surface range in the note before coding L49.6.
