Gestational edema with proteinuria, third trimester

This code signifies the presence of swelling due to fluid retention during the third trimester of pregnancy, accompanied by proteinuria. It indicates a specific form of gestational edema where protein is detected in the urine, but without the elevated blood pressure characteristic of pre-eclampsia.

Apply this code when documentation confirms edema and proteinuria in a pregnant patient during her third trimester, and pre-eclampsia has been ruled out. This diagnosis is typically made after urinalysis reveals significant protein and physical examination notes generalized swelling.

• Ensure documentation explicitly states "third trimester" and "proteinuria" in conjunction with edema.
• Differentiate carefully from pre-eclampsia (O14.x) which includes hypertension; this code is for edema with proteinuria without hypertension.
• Always sequence this code as a secondary diagnosis following the appropriate code for the current pregnancy status (e.g., O09.x).
