Abnormal findings on dx imaging of skull and head, NEC

This code signifies non-specific, abnormal findings identified during imaging studies of the skull and head that do not have a more precise diagnostic code. It indicates an imaging abnormality that requires further investigation or is not yet definitively diagnosed.

Use this code when imaging reports (e.g., CT, MRI, X-ray) describe an abnormality of the skull or head, such as an uncharacterized mass, calcification, or structural anomaly, for which a more specific diagnosis is not provided. It is appropriate when the finding is not definitively identified as an intracranial space-occupying lesion.

• Do not use this code if the imaging report explicitly identifies an intracranial space-occupying lesion; refer to the Excludes1 note.
• Always query the provider for a more specific diagnosis if possible, as this code represents an unspecified finding.
• Sequence this code as a secondary diagnosis when a definitive primary diagnosis related to the patient's symptoms or reason for imaging is known.
