About coding Desquamation
The ICD-10-CM code for Desquamation is R23.4 (Changes in skin texture).
Within R23 (other skin changes), R23.4 is specifically for changes in skin texture. Related codes cover Cyanosis (R23.0), Pallor (R23.1), Flushing (R23.2), spontaneous ecchymoses (R23.3), other skin changes (R23.8) and unspecified skin changes (R23.9).
