About ICD-9-CM 758.81
758.81 is an ICD-9-CM diagnosis code for other conditions due to sex chromosome anomalies. 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 8 ICD-10-CM codes, such as Q97.0 (Karyotype 47, XXX), Q97.1 (Female with more than three X chromosomes) and Q97.2 (Mosaicism, lines with various numbers of X chromosomes). All of these are approximate matches, so review the record to pick the right one.
