CPT® Code 61548

The procedure described by CPT® Code 61548 involves the surgical removal of the pituitary gland or a pituitary tumor using a transnasal or transseptal approach. The pituitary gland is a small, pea-sized endocrine gland located at the base of the skull, specifically in a depression known as the sella turcica, which is situated just behind the bridge of the nose. This gland plays a crucial role in regulating various hormonal functions in the body. Accessing the pituitary gland can be achieved through different surgical approaches, including intracranial, transnasal, or transseptal methods. The transnasal or transseptal approach, as indicated in this code, involves entering the nasal cavity to reach the pituitary gland or tumor. This method is less invasive compared to the intracranial approach, which typically requires a more extensive surgical procedure involving incisions in the scalp and manipulation of the brain tissue. The transnasal approach allows for direct access to the pituitary region while minimizing trauma to surrounding structures, thereby facilitating the excision of the tumor or gland with potentially reduced recovery time for the patient.
