Code Description

ICD-10 O14.90 is a billable code used to indicate a diagnosis of unspecified pre-eclampsia, unspecified trimester.

Key Diagnostic Point:

Unspecified pre-eclampsia is a condition characterized by hypertension and proteinuria that occurs after 20 weeks of gestation. It is a significant complication of pregnancy that can lead to severe maternal and fetal morbidity if not managed appropriately. The diagnosis of pre-eclampsia is made when a pregnant woman presents with elevated blood pressure (≥140/90 mmHg) and protein in the urine (≥300 mg in a 24-hour urine collection). The unspecified trimester designation indicates that the exact timing of the onset of pre-eclampsia is not documented, which can complicate management and coding. Pre-eclampsia can progress to severe features, which include symptoms such as severe headaches, visual disturbances, and elevated liver enzymes, and may lead to HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets), a life-threatening condition. Magnesium sulfate is often administered to prevent seizures in women with severe pre-eclampsia or eclampsia. Accurate coding requires thorough documentation of the patient's clinical status, treatment protocols, and any complications that arise during the course of care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and severity of pre-eclampsia.
  • Need for precise documentation of symptoms and laboratory findings.
  • Differentiation between pre-eclampsia and other hypertensive disorders of pregnancy.
  • Potential for progression to severe features or HELLP syndrome.

Audit Risk Factors

  • Inadequate documentation of blood pressure readings.
  • Failure to document proteinuria or laboratory results.
  • Lack of clarity regarding the trimester of diagnosis.
  • Misclassification of pre-eclampsia severity.

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Documentation must include blood pressure readings, proteinuria results, and any symptoms indicative of severe pre-eclampsia.

Common Clinical Scenarios

A patient presenting with elevated blood pressure and proteinuria during a routine prenatal visit.

Billing Considerations

Consideration of the patient's history and risk factors for pre-eclampsia, such as obesity or previous hypertensive disorders.

Maternal-Fetal Medicine

Documentation Requirements

Detailed documentation of maternal and fetal monitoring, including ultrasound findings and laboratory tests.

Common Clinical Scenarios

Management of a high-risk pregnancy with pre-eclampsia and monitoring for progression to severe features.

Billing Considerations

Focus on the management of complications and coordination of care between obstetricians and maternal-fetal specialists.

  • 10 coding guidelines, pre
  • eclampsia must be coded based on the severity and trimester
  • Documentation must support the diagnosis, including blood pressure readings and proteinuria results
  • The unspecified trimester code is used when the timing of the diagnosis is not clearly documented

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of pre-eclampsia, enabling better tracking of maternal and fetal outcomes. The granularity of the codes helps in understanding the severity and management of the condition.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of pre-eclampsia, enabling better tracking of maternal and fetal outcomes. The granularity of the codes helps in understanding the severity and management of the condition.

Reimbursement & Billing Impact

Frequently Asked Questions

What is the difference between pre-eclampsia and gestational hypertension?

Pre-eclampsia is characterized by hypertension and proteinuria, while gestational hypertension involves elevated blood pressure without proteinuria. Accurate coding requires clear documentation of these distinctions.
