Full Answer
The anterior cranial fossa supports the frontal lobes of the brain. It includes the olfactory grooves where the sense of smell is perceived. The middle part of the anterior cranial fossa forms the roof of the nasal cavity, whereas the outer parts of the anterior cranial fossa form the roofs of the orbits. Meningioma is a common tumor in this area.
The majority of middle cranial fossa tumors are meningiomas; among these, sphenoid wing meningiomas are the most common. The first successful removal of a lateral sphenoid wing meningioma was described in 1774 by Louis A.
Middle Cranial Fossa: The middle portion of the cranial floor is known as the middle cranial fossa (includes the Greater Sphenoid Wing). The middle cranial fossa supports the temporal lobes of the brain and forms the outer walls of the orbits. The bone of the middle cranial fossa separates the ear from the brain.
Currently, only one CPT code exists which describes an endoscopic endonasal approach to a skull base tumor; it is 62165 [ Neuroendoscopy, intracranial; with excision of a pituitary tumor, transnasal or trans-sphenoidal approach].

A meningioma is a primary central nervous system (CNS) tumor. This means it begins in the brain or spinal cord. Overall, meningiomas are the most common type of primary brain tumor. However, higher grade meningiomas are very rare.
The posterior fossa is a small space in the skull, found near the brainstem and cerebellum. The cerebellum is the part of the brain responsible for balance and coordinated movements. The brainstem is responsible for controlling vital body functions, such as breathing.
Grade II (atypical): Approximately 15 percent to-20 percent of meningiomas are atypical, which means that the tumor cells do not appear typical or normal. Atypical meningiomas are neither malignant (cancerous) nor benign, but may become malignant at some point. Grade II meningiomas also tend to recur and grow faster.
Planum sphenoidale meningiomas are extra-axial slow-growing tumors arising from the roof of the sphenoid sinus and the area between the optic nerves and the anterior clinoid processes. Enlargement of this meningiomas usually pushes the optic nerves dorsally and caudally causing vision loss as a primary manifestation.

The ICD code D32 is used to code Meningioma. Meningiomas are a diverse set of tumors arising from the meninges, the membranous layers surrounding the central nervous system. They arise from the arachnoid "cap" cells of the arachnoid villi in the meninges. These tumors usually are benign in nature; however, a small percentage are malignant.
These tumors usually are benign in nature; however, a small percentage are malignant. Many meningiomas produce no symptoms throughout a person's life, and if discovered, require no treatment other than periodic observation. Typically, symptomatic meningiomas are treated with either radiosurgery or conventional surgery.
Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified ( C25.9 ). Neoplasms. Approximate Synonyms. Benign neoplasm of meninges.
All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm. Morphology [Histology] Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, ...
Currently, only one CPT code exists that describes an endoscopic endonasal procedure for resection of a skull base tumor - 62165 [Neuroendoscopy, intracranial; with excision of a pituitary tumor, transnasal or trans-sphenoidal approach]. CPT 62165 is a global service code which means the code includes the approach, tumor resection and direct closure of the operative field.
Presently, there are no existing CPT codes that accurately describe endoscopic endonasal surgery (also known as extended endonasal approach) for removal of a skull base tumor. The endoscopic endonasal pituitary tumor removal code (62165) is intended only for resection of pituitary tumors via this approach. Therefore, per CPT guidelines, an unlisted code must be reported for the endoscopic endonasal approach for removal of non-pituitary neoplastic, vascular or infectious lesions at the base of the skull.
Modifier 82 is used when a faculty surgeon assists another faculty surgeon and a qualified resident is not available. The primary faculty surgeon is responsible for documenting, in the operative note, the presence of the faculty assistant surgeon as well as the unavailability of a qualified resident. Modifier 80 is used for an assistant surgeon in a non-resident setting.
Common tumors in this region are chordoma, chondrosarcoma and meningioma. Foramen Mangum: At the base of the skull lies this large, bony opening, through which the lowest portion of the brain joins and becomes continuous with the spinal cord.
Frontal sinuses, which are located in the forehead; and. Sphenoid sinuses, which are located deep behind the nose. Nasopharynx: Behind the nasal cavity and above the soft palate (the back portion of the roof of the mouth) lies the nasopharynx. This is the top portion of the pharynx, which is the passageway that runs from behind ...
The skull base forms the roof of the parapharyngeal space. The most common tumors in the parapharyngeal space are salivary gland tumors, paragangliomas (or vascular tumors) and tumors of the lower cranial nerves.
The lower cranial nerves designated as IX, X and XI pass from the brain through the jugular foramen into the neck. Clivus: Deep within the head lies the floor of the cranial cavity, which contains the brain. The bone in the central portion of this cranial floor is known as the clivus.
The anterior cranial fossa supports the frontal lobes of the brain. It includes the olfactory grooves where the sense of smell is perceived. The middle part of the anterior cranial fossa forms the roof of the nasal cavity, whereas the outer parts of the anterior cranial fossa form the roofs of the orbits.
Jugular Foramen: The jugular foramen is an opening in the skull base that contains several vital structures. It is located underneath the temporal bone. Blood drains from the brain down to the jugular vein in the neck by passing through the jugular foramen. The lower cranial nerves designated as IX, X and XI pass from the brain through ...
Infratemporal Fossa: This is the space that lies behind the maxilla (the upper jaw) and below the side wall of the skull. It contains several nerves that give sensation to the face, the muscles used for chewing, and several blood vessels, including the carotid artery and the jugular vein. Tumors in this location can come from the ear, ...
The middle cranial fossa is the site of several tumors. These tumors are primarily intracranial, arising from the meninges or cranial nerves, such as meningiomas or schwannomas, while other tumors, such as chordomas and chondrosarcomas, may arise from the bones and cartilages.
The middle cranial fossa is formed by the sphenoid and temporal bones. The anterior border of this fossa consists of the sphenoid wing and anterior clinoid process. Posteriorly, it is limited by the superior border of the petrous temporal bone with the sulcus for the superior petrous sinus, and the dorsum sella of the sphenoid bone.
The middle cranial fossa is a common site of origin for meningiomas. This region can be represented as a rectangular open bowl rising to terminate in three distinct “ridges” and an open back.
