Code Description

ICD-10 O14.02 is a billable code used to indicate a diagnosis of mild to moderate pre-eclampsia, second trimester.

Key Diagnostic Point:

Mild to moderate pre-eclampsia is characterized by the onset of hypertension and proteinuria after 20 weeks of gestation. In the second trimester, this condition may present with blood pressure readings of 140/90 mmHg or higher, along with protein levels in the urine exceeding 300 mg in a 24-hour collection. Symptoms may include mild headaches, visual disturbances, and swelling. It is crucial to monitor the mother and fetus closely, as pre-eclampsia can progress to severe pre-eclampsia or eclampsia, which poses significant risks to both. Management typically involves close observation, lifestyle modifications, and possibly the administration of magnesium sulfate to prevent seizures. The condition requires careful documentation of blood pressure readings, proteinuria levels, and any symptoms experienced by the patient to ensure accurate coding and appropriate care.

Complexity Factors

  • Differentiating between mild and severe pre-eclampsia
  • Accurate measurement and documentation of blood pressure and proteinuria
  • Monitoring for progression to HELLP syndrome
  • Understanding magnesium sulfate protocols and indications

Audit Risk Factors

  • Inadequate documentation of blood pressure and protein levels
  • Failure to note symptoms that may indicate progression
  • Misclassification of pre-eclampsia severity
  • Inconsistent use of magnesium sulfate protocols

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Documentation must include detailed blood pressure readings, proteinuria results, and any symptoms experienced by the patient.

Common Clinical Scenarios

Patients presenting with elevated blood pressure during routine prenatal visits, or those with a history of hypertension.

Billing Considerations

Ensure that all clinical findings are documented to support the diagnosis and management plan.

Maternal-Fetal Medicine

Documentation Requirements

High-risk pregnancy documentation must include comprehensive assessments of maternal and fetal well-being.

Common Clinical Scenarios

Management of patients with a history of pre-eclampsia or those with multiple risk factors.

Billing Considerations

Close monitoring for signs of progression to severe pre-eclampsia or HELLP syndrome is essential.
