R94.3

Abnormal results of cardiovascular function studies

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

Code Description

ICD-10 R94.3 is a billable code used to indicate a diagnosis of abnormal results of cardiovascular function studies.

Key Diagnostic Point:

R94.3 is used to classify abnormal results from cardiovascular function studies, which may include tests such as echocardiograms, stress tests, and electrocardiograms (ECGs). These tests assess the heart's function and can reveal various abnormalities such as arrhythmias, ischemic changes, or structural heart disease. Abnormal findings may manifest as changes in heart rate, rhythm, or response to stress, indicating potential underlying cardiovascular conditions. The interpretation of these results requires careful clinical correlation with the patient's symptoms, history, and other diagnostic findings. Common causes of abnormal results include coronary artery disease, heart failure, valvular heart disease, and cardiomyopathies. Accurate coding necessitates a thorough understanding of the clinical context and the specific abnormalities identified during testing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in test types and interpretations
  • Need for correlation with clinical symptoms
  • Potential overlap with other cardiovascular codes
  • Documentation requirements for specificity

Audit Risk Factors

  • Inadequate documentation of test results
  • Failure to correlate findings with clinical symptoms
  • Misuse of the code for normal variants
  • Inconsistent coding across different providers

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed documentation of test results, clinical correlation, and any relevant patient history.

Common Clinical Scenarios

Patients presenting with chest pain, dyspnea, or palpitations undergoing cardiovascular testing.

Billing Considerations

Ensure that the documentation clearly states the abnormal findings and their clinical significance.

Emergency Medicine

Documentation Requirements

Acute care documentation must include immediate test results and any interventions taken.

Common Clinical Scenarios

Patients with acute chest pain or syncope requiring rapid cardiovascular assessment.

Billing Considerations

Document the urgency of the situation and any immediate actions taken based on abnormal findings.

Coding Guidelines

Inclusion Criteria

Electrocardiogram, ECG, routine ECG with at least 12 leads; with interpretation and report

Clinical Scenario

Used when an ECG is performed and abnormal results are documented.

Documentation Requirements

Ensure the ECG report is included in the patient's medical record.

Specialty Considerations

In cardiology, additional details about the patient's history and symptoms may be required.
