Diagnosis Overview

What is Abnormal Echocardiogram?
Essential facts and insights about Abnormal Echocardiogram

Key Clinical Considerations:

  • Presence of abnormal findings on diagnostic imaging of heart
  • Patient experiencing symptoms such as chest pain, shortness of breath, or irregular heartbeats

Clinical Information

Clinical Criteria & Documentation Requirements

  • Detailed description of the abnormal findings on the echocardiogram
  • Documentation of patient's symptoms and clinical history
  • Specific location and nature of the abnormality

Coding Guidelines

Usage Guidelines & Examples

  • R93.1 is used for abnormal findings on diagnostic imaging of heart, while I50.9 is used for heart failure, unspecified
  • R93.1 should be used when the abnormality is detected through imaging, but the patient may not have symptoms. I50.9 is used when the patient has heart failure symptoms, regardless of imaging results

Code Exclusions
