About ICD-9-CM 757.4
757.4 is an ICD-9-CM diagnosis code for specified anomalies of hair. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 3 ICD-10-CM codes, such as Q84.0 (Congenital alopecia), Q84.1 (Congenital morphological disturbances of hair, not elsewhere classified) and Q84.2 (Other congenital malformations of hair). All of these are approximate matches, so review the record to pick the right one.
