Code Description

ICD-10 O15.00 is a billable code used to indicate a diagnosis of eclampsia complicating pregnancy, unspecified trimester.

Key Diagnostic Point:

Eclampsia is a severe complication of pregnancy characterized by the onset of seizures in a woman with preeclampsia, which is marked by hypertension and proteinuria. The condition can occur at any point during pregnancy, labor, or the postpartum period. Eclampsia poses significant risks to both the mother and fetus, including maternal morbidity and mortality, fetal distress, and preterm delivery. Management of eclampsia typically involves stabilization of the mother, seizure control with medications such as magnesium sulfate, and often an emergency delivery if the condition is severe or unresponsive to treatment. Neurologic complications may arise, including cerebral edema, intracranial hemorrhage, and long-term neurological deficits. Accurate coding of eclampsia is crucial for appropriate treatment reimbursement and tracking of maternal health outcomes.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Differentiating between eclampsia and other hypertensive disorders of pregnancy.
  • Understanding the timing of onset in relation to pregnancy trimesters.
  • Documenting seizure management and emergency interventions accurately.
  • Identifying associated complications and co-morbidities.

Audit Risk Factors

  • Inadequate documentation of seizure activity and management.
  • Failure to document the trimester of pregnancy.
  • Misclassification of eclampsia severity.
  • Omission of associated conditions such as HELLP syndrome.

Frequently Asked Questions

What is the difference between eclampsia and preeclampsia?

Preeclampsia is characterized by high blood pressure and protein in the urine during pregnancy, while eclampsia is the occurrence of seizures in a patient with preeclampsia. Eclampsia is a more severe condition that requires immediate medical intervention.

How is eclampsia managed during labor?

Management during labor includes continuous monitoring of maternal and fetal status, administration of magnesium sulfate for seizure prophylaxis, and preparation for potential emergency delivery if seizures occur.
