About coding Telogen effluvium
The ICD-10-CM code for Telogen effluvium is L65.0 (Telogen effluvium).
Within L65 (other nonscarring hair loss), L65.0 is specifically for Telogen effluvium. Related codes cover Anagen effluvium (L65.1), alopecia mucinosa (L65.2), other specified nonscarring hair loss (L65.8) and nonscarring hair loss, unspecified (L65.9).
Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).
