Gestational edema with proteinuria, first trimester

This code signifies the presence of swelling due to fluid retention (edema) accompanied by protein in the urine (proteinuria) occurring during the first trimester of pregnancy. It indicates a hypertensive disorder of pregnancy that has not yet progressed to pre-eclampsia.

Assign this code when documentation confirms new onset edema and proteinuria in a pregnant patient within the first 13 weeks of gestation, without other signs or symptoms of pre-eclampsia (e.g., hypertension). Supporting documentation would include urinalysis results showing proteinuria and physical exam findings of edema.

• Do not use this code if hypertension is also present; consider codes for pre-eclampsia.
• Ensure the documentation clearly specifies "first trimester" for accurate trimester-specific coding.
• Distinguish from gestational edema without proteinuria (O12.0-) or gestational proteinuria without edema (O12.1-).
