642.42 — Mild or unspecified pre-eclampsia, delivered, with mention of postpartum complication

642.42 is an ICD-9-CM diagnosis code for mild or unspecified pre-eclampsia, delivered, with mention of postpartum complication. 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 O14.02 (Mild to moderate pre-eclampsia, second trimester), O14.03 (Mild to moderate pre-eclampsia, third trimester) and O14.05 (Mild to moderate pre-eclampsia, complicating the puerperium). All of these are approximate matches, so review the record to pick the right one.
