About ICD-9-CM 654.91
654.91 is an ICD-9-CM diagnosis code for other and unspecified abnormality of organs and soft tissues of pelvis, delivered, with or without mention of antepartum condition. 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 7 ICD-10-CM codes, such as O34.29 (Maternal care due to uterine scar from other previous surgery), O34.81 (Maternal care for other abnormalities of pelvic organs, first trimester) and O34.82 (Maternal care for other abnormalities of pelvic organs, second trimester). All of these are approximate matches, so review the record to pick the right one.
