About ICD-9-CM 647.23

647.23 is an ICD-9-CM diagnosis code for other venereal diseases of mother, complicating pregnancy, childbirth, or the puerperium, antepartum condition or complication. 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 O98.311 (Other infections with a predominantly sexual mode of transmission complicating pregnancy, first trimester), O98.312 (Other infections with a predominantly sexual mode of transmission complicating pregnancy, second trimester) and O98.313 (Other infections with a predominantly sexual mode of transmission complicating pregnancy, third trimester). All of these are approximate matches, so review the record to pick the right one.
