ICD-10-CMIntracranial space-occupying lesion found on diagnostic imaging of central nervous system
This code signifies the presence of an abnormal mass or growth within the cranial cavity, identified through imaging studies of the brain or spinal cord. It indicates a finding that occupies space and could potentially exert pressure on surrounding neural structures, but the specific nature (e.g., tumor, cyst, hematoma) is not yet definitively known.
Use this code when diagnostic imaging (e.g., MRI, CT scan) reveals an intracranial lesion that is not yet definitively diagnosed as benign or malignant, or when the specific pathology is still under investigation. Documentation should clearly state "space-occupying lesion," "mass," or "lesion" identified on imaging, without a more specific diagnosis.
