CPT® Code 61750

Stereotactic biopsy, aspiration, or excision is a minimally invasive procedure designed to obtain tissue samples or remove lesions from deep within the brain that are not accessible through traditional open surgical techniques. This procedure is particularly useful for targeting intracranial lesions, such as tumors or other abnormal masses, that require precise localization for effective treatment. A specialized frame is securely attached to the patient's skull to stabilize the head and ensure accuracy during the procedure. Imaging techniques, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans, are employed to create detailed maps of the brain, allowing healthcare professionals to identify the exact location of the lesion. In some cases, angiography may also be utilized to visualize blood vessels in the area of interest. To perform a biopsy, a stereotactic biopsy apparatus is aligned with the coordinates obtained from the imaging studies, guiding the insertion of a biopsy probe through a small incision made in the scalp. The probe is carefully advanced to the targeted lesion, where tissue samples are collected for pathological examination. In cases where aspiration of fluid is necessary, a stereotactic aspiration device is used instead of a biopsy probe. For excision procedures, specialized surgical instruments are introduced through one or more burr holes to remove the lesion in a piecemeal manner. After the procedure, the burr hole is typically filled with bone wax to promote healing, and the incision in the skin is closed. The stereotactic frame is then removed, completing the procedure. It is important to note that CPT® Code 61750 is used when the procedure is performed without the assistance of CT or MRI guidance, while CPT® Code 61751 is designated for procedures that utilize these imaging modalities.
