Code Description

ICD-10 O14.13 is a billable code used to indicate a diagnosis of severe pre-eclampsia, third trimester.

Key Diagnostic Point:

Severe pre-eclampsia is a serious pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, typically occurring after 20 weeks of gestation. In the third trimester, the condition can escalate rapidly, leading to severe maternal and fetal complications. Clinical features of severe pre-eclampsia include blood pressure readings of 160/110 mmHg or higher, significant proteinuria, and symptoms such as severe headaches, visual disturbances, and upper abdominal pain. HELLP syndrome, a severe form of pre-eclampsia, involves hemolysis, elevated liver enzymes, and low platelet count, posing additional risks to both mother and fetus. Management often includes the administration of magnesium sulfate to prevent seizures, alongside antihypertensive medications to control blood pressure. Close monitoring of both maternal and fetal well-being is essential, and delivery is often the definitive treatment to mitigate risks associated with this condition.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Differentiating between mild and severe pre-eclampsia
  • Identifying associated conditions like HELLP syndrome
  • Understanding the implications of magnesium sulfate administration
  • Navigating documentation requirements for high-risk pregnancies

Audit Risk Factors

  • Inadequate documentation of blood pressure readings
  • Failure to document symptoms associated with severe pre-eclampsia
  • Misclassification of pre-eclampsia severity
  • Lack of clarity on treatment protocols like magnesium sulfate use
