About ICD-9-CM 620.4
620.4 is an ICD-9-CM diagnosis code for prolapse or hernia of ovary and fallopian tube. 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 N83.40 (Prolapse and hernia of ovary and fallopian tube, unspecified side), N83.41 (Prolapse and hernia of right ovary and fallopian tube) and N83.42 (Prolapse and hernia of left ovary and fallopian tube). All of these are approximate matches, so review the record to pick the right one.
