About coding severe pre-eclampsia
The ICD-10-CM code for severe pre-eclampsia is O14.1 (Severe pre-eclampsia). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O14.1.
Within O14 (pre-eclampsia), O14.1 is specifically for severe pre-eclampsia. Related codes cover mild to moderate pre-eclampsia (O14.0), HELLP syndrome (O14.2) and unspecified pre-eclampsia (O14.9).
To report this condition, pick the subcode that matches the documentation: O14.10 (unspecified trimester), O14.12 (second trimester), O14.13 (third trimester), O14.14 (complicating childbirth) and O14.15 (complicating the puerperium).
Don't report O14.1 together with the conditions in its Excludes1 note: HELLP syndrome (O14.2-).
