Code Description

ICD-10 O12.02 is a billable code used to indicate a diagnosis of gestational edema, second trimester.

Key Diagnostic Point:

Gestational edema refers to the swelling that occurs during pregnancy, particularly in the second trimester, due to fluid retention. This condition is characterized by the accumulation of excess fluid in the body's tissues, leading to swelling, particularly in the lower extremities. Unlike preeclampsia, gestational edema in this context does not involve hypertension or significant proteinuria. It is essential to monitor the patient's symptoms and ensure that the edema is not indicative of underlying complications such as gestational hypertension or other cardiovascular issues. Clinical management may include lifestyle modifications, such as increased physical activity, dietary changes, and elevation of the legs to reduce swelling. Regular follow-up visits are crucial to assess the progression of edema and to rule out any potential complications. Accurate documentation of the patient's symptoms, the absence of hypertension, and any interventions provided is vital for proper coding and billing.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between gestational edema and other forms of edema.
  • Monitoring for signs of hypertension or proteinuria.
  • Documenting the absence of hypertension accurately.
  • Understanding the implications of gestational edema on maternal and fetal health.

Audit Risk Factors

  • Inadequate documentation of symptoms and treatment.
  • Failure to differentiate from preeclampsia.
  • Misclassification of the severity of edema.
  • Inaccurate coding of associated conditions.
