Code Description

ICD-10 O14.0 is a billable code used to indicate a diagnosis of mild to moderate pre-eclampsia.

Key Diagnostic Point:

Mild to moderate pre-eclampsia is a pregnancy complication characterized by the onset of hypertension and proteinuria after 20 weeks of gestation. It is defined by systolic blood pressure readings of 140-159 mmHg or diastolic readings of 90-109 mmHg, along with proteinuria levels of 300 mg or more in a 24-hour urine collection. This condition can lead to serious complications for both the mother and fetus if not monitored and managed appropriately. Symptoms may include swelling, sudden weight gain, and headaches. Management typically involves close monitoring of blood pressure, fetal well-being, and may include the administration of magnesium sulfate to prevent seizures, especially if there are concerns about progression to severe pre-eclampsia or eclampsia. Regular prenatal visits and laboratory tests are crucial for early detection and intervention. The condition can resolve after delivery, but ongoing monitoring is essential to ensure maternal and fetal health.

  • Understanding the implications of proteinuria levels
  • Monitoring for progression to HELLP syndrome
  • Managing magnesium sulfate protocols and dosages

Audit Risk Factors

  • Inaccurate blood pressure readings documented
  • Failure to document proteinuria testing results
  • Inconsistent monitoring of maternal and fetal health
  • Lack of clear treatment plans or protocols followed

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

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

Common Clinical Scenarios

Patients presenting with elevated blood pressure during routine prenatal visits, or those with sudden weight gain and edema.

Billing Considerations

Ensure that all assessments are documented clearly to avoid confusion with severe pre-eclampsia or other hypertensive disorders.

Maternal-Fetal Medicine

Documentation Requirements

Detailed documentation of high-risk factors, fetal monitoring results, and any interventions performed.

Common Clinical Scenarios

Management of patients with a history of pre-eclampsia or those presenting with symptoms suggestive of progression.

Billing Considerations

Focus on the management of potential complications and the need for multidisciplinary care.
