About ICD-9-CM 634.01
634.01 is an ICD-9-CM diagnosis code for spontaneous abortion, complicated by genital tract and pelvic infection, incomplete. 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 2 ICD-10-CM codes, such as O03.0 (Genital tract and pelvic infection following incomplete spontaneous abortion) and O03.37 (Sepsis following incomplete spontaneous abortion). All of these are approximate matches, so review the record to pick the right one.
