Abnormal findings on diagnostic imaging of other body structures (R93)

The ICD-10 code R93 and its subcodes describe abnormal findings detected through diagnostic imaging of various body structures when no specific diagnosis is yet established. These codes capture unexpected or unclear radiologic results across different organs and systems.

This section includes codes like R93.0 for unusual imaging of the skull or head (commonly known by terms such as MRI or CT of the head abnormal), R93.1 for heart and coronary circulation anomalies detected by echocardiogram or angiography, and R93.2 for abnormal liver or biliary tract imaging. Other subcategories cover the digestive tract (R93.3), urinary organs (R93.4), limbs (R93.6), and musculoskeletal system (R93.7). For example, imaging abnormalities in the kidneys are detailed under R93.42 and its more specific codes for right or left kidney findings. Additionally, R93.89 covers diverse abnormal radiologic densities and lesion shapes, aiding coders in assigning accurate codes for atypical imaging results. This section is essential for capturing findings like incidental opacities, masses, or unusual calcifications that require further clinical evaluation.
