Exfoliation due to erythematous conditions according to extent of body surface involved (L49) ICD-10-CM
The L49 code range covers exfoliation due to erythematous conditions according to extent of body surface involved with 11 ICD-10-CM diagnosis codes. 10 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

Exfoliation means skin peeling. Here, it results from an erythematous condition, one marked by redness.
