About ICD-9-CM 649.41
649.41 is an ICD-9-CM diagnosis code for epilepsy complicating pregnancy, childbirth, or the puerperium, 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 4 ICD-10-CM codes, such as O99.351 (Diseases of the nervous system complicating pregnancy, first trimester), O99.352 (Diseases of the nervous system complicating pregnancy, second trimester) and O99.353 (Diseases of the nervous system complicating pregnancy, third trimester). All of these are approximate matches, so review the record to pick the right one.
