R03.0

Elevated blood-pressure reading, without diagnosis of hypertension

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R03.0 is a billable code used to indicate a diagnosis of elevated blood-pressure reading, without diagnosis of hypertension.

Key Diagnostic Point:

R03.0 is used to classify elevated blood pressure readings that do not meet the criteria for a diagnosis of hypertension. This code is applicable when a patient presents with a blood pressure reading that is higher than normal but does not fulfill the diagnostic criteria for hypertension, which typically requires multiple elevated readings over time. Elevated blood pressure can be a transient condition influenced by various factors such as stress, anxiety, physical activity, or recent consumption of caffeine or nicotine. It is crucial for healthcare providers to assess the context of the elevated reading, including the patient's medical history, lifestyle factors, and any accompanying symptoms. Proper documentation is essential to differentiate between isolated elevated readings and those indicative of chronic hypertension, ensuring appropriate management and follow-up. This code serves as a flag for potential cardiovascular risk and may prompt further evaluation or monitoring.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between transient elevated readings and chronic hypertension.
  • Need for thorough documentation of patient history and context.
  • Potential for misclassification if not properly assessed.
  • Variability in blood pressure readings based on situational factors.

Audit Risk Factors

  • Inadequate documentation of the circumstances surrounding the elevated reading.
  • Failure to follow up on elevated readings leading to misdiagnosis.
  • Coding elevated readings without appropriate clinical context.
  • Misinterpretation of isolated readings as chronic conditions.

Specialty Focus

Internal Medicine

Documentation Requirements

Document the patient's blood pressure readings, any relevant symptoms, and the context of the readings (e.g., stress, recent activity).

Common Clinical Scenarios

Routine check-ups where patients present with elevated readings but no history of hypertension.

Billing Considerations

Consider lifestyle factors and family history that may contribute to elevated readings.

Emergency Medicine

Documentation Requirements

Document the acute presentation, vital signs, and any immediate interventions taken.

Common Clinical Scenarios

Patients presenting with elevated blood pressure due to acute stress or pain.

Billing Considerations

Ensure that the elevated reading is not part of a hypertensive emergency.
