CPT® Code 61601

Resection or excision of neoplastic, vascular or infectious lesion of base of anterior cranial fossa; intradural, including dural repair, with or without graft

The CPT® Code 61601 refers to the surgical procedure involving the resection or excision of neoplastic, vascular, or infectious lesions located at the base of the anterior cranial fossa. This procedure is performed intradurally, which means it involves accessing the area beneath the dura mater, the protective membrane covering the brain. The operation includes dural repair, which is essential for maintaining the integrity of the central nervous system and preventing complications such as cerebrospinal fluid leaks. The procedure may be conducted with or without the use of graft materials, depending on the specific requirements of the case. The anterior cranial fossa is accessed through a separately reported approach, allowing for a thorough examination and treatment of lesions that may affect critical structures such as the olfactory bulb, cranial nerves, and blood vessels. The careful execution of this procedure is vital to ensure the preservation of these structures while effectively removing the lesion and repairing any dural defects that may arise during the operation.
