About ICD-9-CM V12.3
V12.3 is an ICD-9-CM diagnosis code for personal history of diseases of blood and blood-forming organs. 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 one ICD-10-CM code, Z86.2 (Personal history of diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism). The match is approximate, so confirm it against the record.
