2015
Non-Billable Code

There are 5 ICD-9-CM codes below 642.4 that define this diagnosis in greater detail. Do not use this code on a reimbursement claim.

Clinical Information

Pregnancy induced hypertensive states, including eph gestosis when edema and proteinuria accompany hypertension; other hypertensive disorders that develop during pregnancy or the puerperium are preeclampsia and eclampsia, either of which may be superimposed upon chronic hypertensive vascular or renal disease
Toxemia occurring in women in the second half of their pregnancy, characterized by hypertension, and usually by edema and proteinuria, but without the convulsions and coma associated with eclampsia

642.4 Excludes

albuminuria in pregnancy, without mention of hypertension (646.2)
edema in pregnancy, without mention of hypertension (646.1)

Applies To

Hypertension in pregnancy, childbirth, or the puerperium, not specified as pre-existing, with either albuminuria or edema, or both; mild or unspecified
Pre-eclampsia:
- NOS
- mild
Toxemia (pre-eclamptic):
- NOS
- mild
