Code Description

ICD-10 O12.03 is a billable code used to indicate a diagnosis of gestational edema, third trimester.

Key Diagnostic Point:

Gestational edema refers to the accumulation of excess fluid in the tissues during pregnancy, particularly in the third trimester. This condition is characterized by swelling, primarily in the lower extremities, and can also affect the hands and face. It is important to note that gestational edema can occur without the presence of hypertension or proteinuria, distinguishing it from conditions such as preeclampsia. The pathophysiology of gestational edema is often related to increased blood volume and hormonal changes that occur during pregnancy, leading to fluid retention. Clinically, it is essential to monitor the extent of edema and differentiate it from more serious conditions that may require intervention. Management typically involves lifestyle modifications, such as elevating the legs, reducing salt intake, and ensuring adequate hydration. Regular follow-up is crucial to ensure that the edema does not progress to more severe complications.

Frequently Asked Questions

What is the difference between gestational edema and preeclampsia?

Gestational edema is characterized by swelling without hypertension or proteinuria, while preeclampsia involves elevated blood pressure and protein in the urine, indicating a more serious condition.
