Abnormal findings on diagnostic imaging of limbs

This code signifies an abnormal finding identified during diagnostic imaging (e.g., X-ray, MRI, CT scan, ultrasound) of any limb, including the upper and lower extremities. It indicates that an imaging study revealed a deviation from normal anatomy or physiology, but a more specific diagnosis is not yet established or available.

Use this code when diagnostic imaging of a limb reveals an abnormality, and the provider's documentation does not specify a definitive diagnosis. This is often an initial finding that requires further investigation or clinical correlation. Documentation should clearly state an abnormal finding on imaging of an upper or lower extremity.

• Do not use this code if a more specific diagnosis for the abnormal finding is documented (e.g., fracture, tumor, arthritis).
• This code is typically sequenced as a primary diagnosis when the abnormal finding is the reason for the encounter, or as a secondary diagnosis when it's an incidental finding.
• Ensure documentation specifies the limb involved and the type of imaging performed to support the code.
