Code Description

ICD-10 O15.0 is a billable code used to indicate a diagnosis of eclampsia complicating pregnancy.

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 seizures can occur before, during, or after labor and are often a result of cerebral edema or other neurological complications associated with severe hypertension. Management of eclampsia typically involves stabilizing the patient, controlling seizures with medications such as magnesium sulfate, and addressing the underlying hypertension. Emergency delivery may be necessary to prevent further complications for both the mother and the fetus. Neurologic complications can include stroke, permanent neurological deficits, or even maternal mortality if not managed promptly. The condition requires immediate medical attention and a multidisciplinary approach to ensure the safety of both the mother and the newborn.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Differentiating between eclampsia and other seizure disorders
  • Understanding the timing of seizures in relation to labor and delivery
  • Managing co-existing conditions such as gestational hypertension
  • Documentation of seizure frequency and duration

Audit Risk Factors

  • Inadequate documentation of seizure activity
  • Failure to document the timing of seizures in relation to delivery
  • Misclassification of eclampsia severity
  • Lack of clarity in the management plan for eclampsia

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Detailed records of maternal vital signs, seizure activity, and treatment protocols.

Common Clinical Scenarios

Management of eclampsia during labor, postpartum seizures, and stabilization of the mother.

Billing Considerations

Accurate documentation of the timing of seizures and interventions is critical for coding.

Maternal-Fetal Medicine

Documentation Requirements

Comprehensive records of maternal-fetal assessments, including fetal monitoring during seizures.

Common Clinical Scenarios

High-risk pregnancies with preeclampsia leading to eclampsia.

Billing Considerations

Consideration of fetal outcomes and maternal health in coding decisions.

Coding Guidelines

Inclusion Criteria

Use O15.0 When
  • Follow the ICD
  • CM guidelines for coding eclampsia, ensuring that the diagnosis is supported by clinical documentation of seizures and associated conditions
  • The use of additional codes for hypertension and other complications may be necessary

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 requiring immediate medical intervention.
