About coding pre-eclampsia
The ICD-10-CM code for pre-eclampsia is O14.9 (Unspecified pre-eclampsia). The official index lists 14 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O14.9.
Within O14, choose O14.9 (Unspecified pre-eclampsia) only when documentation doesn't support a more specific option: mild to moderate pre-eclampsia (O14.0), severe pre-eclampsia (O14.1) and HELLP syndrome (O14.2).
To report this condition, pick the subcode that matches the documentation: O14.90 (unspecified trimester), O14.92 (second trimester), O14.93 (third trimester), O14.94 (complicating childbirth) and O14.95 (complicating the puerperium).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
