Code Description

ICD-10 O14.1 is a billable code used to indicate a diagnosis of severe pre-eclampsia.

Key Diagnostic Point:

Severe pre-eclampsia is a serious pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, most often the liver and kidneys. It typically occurs after the 20th week of gestation and can lead to significant maternal and fetal morbidity if not managed appropriately. The condition is defined by a blood pressure reading of 160/110 mmHg or higher, along with the presence of proteinuria (excess protein in urine) or other severe features such as elevated liver enzymes, low platelet count, or severe headaches. HELLP syndrome, which stands for Hemolysis, Elevated Liver enzymes, and Low Platelet count, is a severe manifestation of pre-eclampsia that requires immediate medical intervention. Management often includes the administration of magnesium sulfate to prevent seizures, antihypertensive medications to control blood pressure, and timely delivery of the baby, which is the only definitive cure for pre-eclampsia. Close monitoring of both maternal and fetal well-being is essential during this critical period.

Complexity Factors

  • Differentiating between mild and severe pre-eclampsia
  • Identifying and documenting associated conditions like HELLP syndrome
  • Understanding the nuances of magnesium sulfate administration protocols
  • Navigating the timing and method of delivery in severe cases

Audit Risk Factors

  • Inadequate documentation of blood pressure readings
  • Failure to document the presence of proteinuria
  • Misclassification of pre-eclampsia severity
  • Lack of clear treatment protocols followed
