In simple words: This code describes swelling and protein in the urine during pregnancy, but without high blood pressure.It's only used for the mother's medical record.

This code is used to classify cases of gestational edema (swelling) accompanied by proteinuria (protein in the urine) during pregnancy.It is specifically for instances where these conditions occur without the presence of hypertension (high blood pressure).This diagnosis should only be applied to maternal records and not to newborn records.The presence and severity of edema and proteinuria should be documented.

Example 1: A 30-year-old pregnant woman at 26 weeks gestation presents with significant lower extremity edema and a urine dipstick showing 2+ protein. Blood pressure is within normal limits. Code O12.2 is appropriate., A 25-year-old pregnant woman at 32 weeks gestation reports mild ankle swelling and increased urination.Urinalysis reveals 1+ protein. Blood pressure is normal.Code O12.2 is assigned.Further monitoring is advised., A 35-year-old patient at 38 weeks gestation presents with facial swelling and generalized edema.Urinalysis shows moderate proteinuria.Blood pressure remains stable. Code O12.2 is assigned along with additional codes as clinically indicated to fully reflect the patient's condition.

Complete documentation of the physical examination focusing on edema (location, severity), urinalysis results with quantification of protein, blood pressure readings, and gestational age are necessary.Any other relevant findings or comorbidities should be documented.

** This code should be used cautiously and in conjunction with comprehensive clinical documentation.It's important to distinguish this code from conditions involving hypertension (O14) or pre-existing hypertension with superimposed proteinuria (O11).
