Resection of Malignant Neoplasm of Infratemporal Fossa
The patient was admitted for surgical treatment of a left infratemporal fossa malignancy with perineural invasion. It appears that the patient underwent en bloc resection of the tumor. The surgeon excised the infratemporal fossa tumor using a preauricular approach, including left parotidectomy with facial nerve dissection; left modified radical neck dissection level 1, 2, 3, and 4; and resection of neoplastic lesion involving fibroconnective tissue, with sacrifice of the hypoglossal nerve, spinal accessory nerve, internal jugular vein, and external carotid artery. Areas resected included: the head, face, lower jaw and neck, facial nerves, vessels, and muscles. Should ICD-10-PCS codes be assigned for all of the sites excised? How is this surgery coded? ...

Article Overview
This premium article explains how to approach ICD-10-PCS coding for a complex head and neck cancer resection centered in the infratemporal fossa. It is relevant to inpatient coders, HIM professionals, and auditors who handle operative reports involving multi-structure tumor removal, neck dissection, and related anatomic sites. The article covers how the operative narrative is interpreted, how the procedure is characterized at a high level, and how the coding discussion is framed for this type of case.
Why This Topic Matters
Complex oncologic surgeries in the head and neck region can involve several connected anatomic areas, making accurate procedure classification important for inpatient coding and record abstraction. This article helps readers understand the scope of the surgery and the type of coding analysis applied to such cases.
