Gestational [pregnancy-induced] edema and proteinuria without hypertension (O12)

The ICD-10 code O12 and its subcodes identify various forms of gestational edema and proteinuria that occur during pregnancy without the presence of hypertension. These codes are used to specify the timing and nature of these pregnancy-induced conditions.

The section covers conditions such as gestational edema and gestational proteinuria, which may be recorded independently or together, indicated by codes from O12.0 to O12.2 with additional specificity by trimester or related to childbirth and the postpartum period. For example, O12.00 represents gestational edema without hypertension in any trimester, sometimes called “gestational edema without hypertension,” while O12.10 denotes gestational proteinuria, also known as “persistent gestational proteinuria” or “albuminuria in pregnancy without hypertension.” The combined condition of gestational edema with proteinuria; also recognized as “pregnancy-induced edema and proteinuria without hypertension”; is coded under O12.20 and related extensions.

These ICD-10 codes help healthcare providers and coders accurately document and manage pregnancy complications that involve swelling and abnormal protein in urine but exclude high blood pressure, aiding in proper tracking and treatment during different pregnancy stages.
