Code Description

ICD-10 O14.12 is a billable code used to indicate a diagnosis of severe pre-eclampsia, second trimester.

Key Diagnostic Point:

Severe pre-eclampsia is a serious pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, most often the liver and kidneys. In the second trimester, this condition can manifest with severe hypertension (blood pressure ≥160/110 mmHg), proteinuria, and symptoms such as severe headaches, visual disturbances, and upper abdominal pain. The presence of severe features may also indicate the development of HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets), which can lead to significant maternal and fetal morbidity. Management typically involves close monitoring, antihypertensive medications, and the administration of magnesium sulfate to prevent seizures. The timing and mode of delivery are critical decisions that depend on the severity of the condition and gestational age. Prompt recognition and treatment are essential to improve outcomes for both the mother and the fetus.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Differentiating between mild and severe pre-eclampsia based on clinical features.
  • Understanding the implications of HELLP syndrome and its management.
  • Navigating the use of magnesium sulfate protocols and their documentation.
  • Recognizing the need for timely intervention and potential delivery planning.

Audit Risk Factors

  • Inadequate documentation of blood pressure readings and proteinuria.
  • Failure to document the presence of severe features or HELLP syndrome.
  • Incorrect coding of the gestational age at diagnosis.
  • Lack of clarity in treatment protocols, especially regarding magnesium sulfate administration.

Frequently Asked Questions

What are the key features that differentiate severe pre-eclampsia from mild pre-eclampsia?

Severe pre-eclampsia is characterized by significantly elevated blood pressure (≥160/110 mmHg), severe symptoms such as headaches and visual disturbances, and potential organ dysfunction, including HELLP syndrome, whereas mild pre-eclampsia has lower blood pressure and fewer severe symptoms.
