New ICD-10 Codes for Gestational Diabetes and Pre-eclampsia in postpartum
Gestational Diabetes ICD-10 Codes: New codes have been added to indicate when gestational diabetes (diabetes that starts during pregnancy) is controlled by oral hypoglycemic drugs, during pregnancy, childbirth or in the puerperium:
O24.415 Gestational diabetes mellitus in pregnancy, controlled by oral hypoglycemic drugs
O24.425 Gestational diabetes mellitus in childbirth, controlled by oral hypoglycemic drugs
O24.435 Gestational diabetes mellitus in puerperium, controlled by oral hypoglycemic drugs
Pre-existing Hypertension, Gestational Edema/Proteinuria/Hypertension, Pre-eclampsia, Eclampsia and HELLP Syndrome. For the mentioned pregnancy complications, ‘complicating childbirth’ and ‘complicating puerperium’ have been added to the following codes:
O11.4 Pre-existing hypertension with pre-eclampsia, complicating childbirth
O11.5 Pre-existing hypertension with pre-eclampsia, complicating the puerperium
O12.04 Gestational edema, complicating childbirth
O12.05 Gestational edema, complicating the puerperium
O12.14 Gestational proteinuria, complicating childbirth
O12.15 Gestational proteinuria, complicating the puerperium
O12.24 Gestational edema with proteinuria, complicating childbirth
O12.25 Gestational edema with proteinuria, complicating the puerperium
O13.4 Gestational [pregnancy-induced] hypertension without significant proteinuria, complicating childbirth
O13.5 Gestational [pregnancy-induced] hypertension without significant proteinuria, complicating the puerperium
O14.04 Mild to moderate pre-eclampsia, complicating childbirth
O14.05 Mild to moderate pre-eclampsia, complicating the puerperium
O14.14 Severe pre-eclampsia complicating childbirth
O14.15 Severe pre-eclampsia, complicating the puerperium
O14.24 HELLP syndrome, complicating childbirth
O14.25 HELLP syndrome, complicating the puerperium
O14.94 Unspecified pre-eclampsia, complicating childbirth
O14.95 Unspecified pre-eclampsia, complicating the puerperium
O16.4 Unspecified maternal hypertension, complicating childbirth
O16.5 Unspecified maternal hypertension, complicating the puerperium
The below codes consist of a 4th or 5th character for childbirth and the puerperium. The exception to this rule is for eclampsia, which identifies the 4th character as ‘1’ for childbirth and ‘2’ for the puerperium:
O15.1 Eclampsia complicating labor
O15.2 Eclampsia complicating the puerperium
O15.9 Eclampsia, unspecified as to time period
For Eclampsia codes the word ‘in’ has been replaced with ‘complicating” to keep consistent with other complications within Chapter 15.
