R94.39

Abnormal result of other cardiovascular function study

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

Code Description

ICD-10 R94.39 is a billable code used to indicate a diagnosis of abnormal result of other cardiovascular function study.

Key Diagnostic Point:

The ICD-10 code R94.39 is used to classify abnormal results from cardiovascular function studies that do not fall under more specific categories. These studies may include various diagnostic tests such as echocardiograms, stress tests, or Holter monitoring, which assess the heart's function and performance. Abnormal results can indicate a range of cardiovascular issues, including arrhythmias, ischemic heart disease, or heart failure. Symptoms associated with these abnormalities may include chest pain, palpitations, shortness of breath, or fatigue. The interpretation of these results requires careful clinical correlation with the patient's history and physical examination findings to determine the underlying cause and appropriate management. It is crucial for healthcare providers to document the specific nature of the abnormal findings and any related symptoms to ensure accurate coding and billing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying conditions that can lead to abnormal results.
  • Need for comprehensive documentation linking symptoms to test results.
  • Variability in test types and interpretations across different specialties.
  • Potential overlap with other cardiovascular codes, requiring careful differentiation.

Audit Risk Factors

  • Inadequate documentation linking abnormal results to specific symptoms.
  • Failure to specify the type of cardiovascular study performed.
  • Misuse of the code when more specific codes are applicable.
  • Lack of follow-up documentation or treatment plans related to abnormal findings.

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Documentation should include the type of cardiovascular study performed, the specific abnormal findings, and any related symptoms or clinical context.

Common Clinical Scenarios

Patients presenting with atypical chest pain, fatigue, or palpitations undergoing stress testing or echocardiography.

Billing Considerations

Ensure that the clinical significance of the abnormal findings is clearly documented to support the use of R94.39.

Emergency Medicine

Documentation Requirements

Acute care documentation must detail the patient's presenting symptoms, the cardiovascular studies performed, and the interpretation of results.

Common Clinical Scenarios

Patients with acute chest pain or syncope undergoing immediate cardiovascular evaluation.

Billing Considerations

Rapid documentation is essential; ensure that abnormal findings are linked to the patient's acute presentation.

Coding Guidelines

Inclusion Criteria

Use R94.39 When

Frequently Asked Questions

What types of studies are included under R94.39?

R94.39 encompasses various cardiovascular function studies, including but not limited to echocardiograms, stress tests, and Holter monitoring, as long as the results are abnormal and not classified elsewhere.

How do I ensure accurate coding for abnormal cardiovascular findings?

Accurate coding requires clear documentation linking the abnormal findings to the patient's symptoms, specifying the type of study performed, and ensuring that no more specific codes are applicable.
