About coding mucinosa alopecia
The ICD-10-CM code for mucinosa alopecia is L65.2 (Alopecia mucinosa).
Within L65 (other nonscarring hair loss), L65.2 is specifically for alopecia mucinosa. Related codes cover Telogen effluvium (L65.0), Anagen effluvium (L65.1), 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).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
