About O14.2

O14.2 is the ICD-10-CM diagnosis code for HELLP syndrome. It belongs to category O14 (pre-eclampsia), block O10-O16 (edema, proteinuria and hypertensive disorders in pregnancy, childbirth and the puerperium) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within O14 (pre-eclampsia), O14.2 is specifically for HELLP syndrome. Related codes cover mild to moderate pre-eclampsia (O14.0), severe pre-eclampsia (O14.1) and unspecified pre-eclampsia (O14.9).

To report this condition, pick the subcode that matches the documentation: O14.20 ((HELLP), unspecified trimester), O14.22 ((HELLP), second trimester), O14.23 ((HELLP), third trimester), O14.24 (complicating childbirth) and O14.25 (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.
