ICD-10-CM O13: Gestational [pregnancy-induced] Hypertension Without Significant Proteinuria Overview
The diagnoses in this group represent new-onset hypertension occurring after 20 weeks of pregnancy without clinically significant proteinuria or features of preeclampsia. These codes target hypertensive disorders specific to pregnancy and the puerperium and relate to maternal cardiovascular and obstetric care. Accurate coding matters because it supports appropriate reimbursement and ensures the medical record reflects pregnancy-specific risk for monitoring and care coordination.
