About coding HELLP syndrome

The ICD-10-CM code for HELLP syndrome is O14.2 (HELLP syndrome). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O14.2.

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.
