Gestational proteinuria, third trimester

This code signifies the presence of proteinuria that develops during pregnancy, specifically identified in the third trimester, without evidence of hypertension or other signs of pre-eclampsia. It indicates isolated protein in the urine during the later stages of gestation.

Use this code when documentation clearly states gestational proteinuria occurring in the third trimester, and there is no mention of elevated blood pressure or other pre-eclamptic features. This diagnosis is typically made after ruling out other causes of proteinuria.

• Differentiate from pre-eclampsia (O14.x) which includes hypertension.
• Ensure the trimester is explicitly documented; if not specified, query the provider.
• Code also any associated conditions or complications, if applicable.
