About ICD-9-CM 658.01

658.01 is an ICD-9-CM diagnosis code for oligohydramnios, 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 3 ICD-10-CM codes, such as O41.01X0 (Oligohydramnios, first trimester, not applicable or unspecified), O41.02X0 (Oligohydramnios, second trimester, not applicable or unspecified) and O41.03X0 (Oligohydramnios, third trimester, not applicable or unspecified). All of these are approximate matches, so review the record to pick the right one.
