About the O10–O16 Code Range
Swelling, protein in the urine, and high blood pressure during pregnancy, childbirth, or after delivery appear here. The categories separate pre-existing high blood pressure from conditions that arise during pregnancy.
O10 groups pre-existing high blood pressure by type and associated heart or kidney disease. Pre-eclampsia is a pregnancy complication involving high blood pressure and protein in the urine, with or without swelling. O11 combines pre-existing high blood pressure with pre-eclampsia. O12 separates pregnancy-related swelling, protein in the urine, and both together, without high blood pressure.
O13 describes pregnancy-induced high blood pressure without significant protein in the urine. O14 distinguishes pre-eclampsia by severity and identifies HELLP syndrome. Eclampsia means heightened reflexes, seizures, or coma beginning in someone already diagnosed with pre-eclampsia. O15 separates eclampsia during pregnancy, labor, and the period after childbirth. O16 describes unspecified maternal high blood pressure. Subdivisions of O11, O13, and O16 distinguish pregnancy trimester, childbirth, and the period after childbirth.
