Abnormal brain scan

This code indicates an abnormal finding on a diagnostic imaging study of the brain, such as a CT scan, MRI, or nuclear medicine scan. It signifies that the radiologist or interpreting physician has identified a deviation from normal brain anatomy or function based on the imaging results. This could include findings like lesions, atrophy, edema, or vascular abnormalities.

This code is appropriate when a brain imaging study reveals an abnormal finding, but a more specific diagnosis cannot yet be definitively established. It is often used as a preliminary diagnosis while further investigation or clinical correlation is pending. Documentation should clearly state "abnormal brain scan" or describe a non-specific abnormal finding on a brain imaging report.

• Do not use this code if a more specific diagnosis (e.g., cerebral infarction, brain tumor) is documented and confirmed by the imaging.
• Sequence this code as a primary diagnosis when the abnormal scan is the reason for the encounter, or as a secondary diagnosis when it's an incidental finding.
• Always review the full radiology report for definitive findings before assigning this non-specific code.
