01.2 Craniotomy And Craniectomy
Decompressive craniectomy is a neurosurgical procedure in which part of the skull is removed to allow a swelling brain room to expand without being squeezed. It is performed on victims of traumatic brain injury, stroke and other conditions associated with raised intracranial pressure. Us…
The new codes are for describing the infusion of tixagevimab and cilgavimab monoclonal antibody (code XW023X7), and the infusion of other new technology monoclonal antibody (code XW023Y7).

Why ICD-10 codes are important
Resection is similar to excision except it involves cutting out or off, without replacement, all of a body part. Resection includes all of a body part or any subdivision of a body part having its own body part value in ICD-10-PCS, while excision includes only a portion of a body part.

A Craniectomy is similar to a craniotomy as both procedures involve removing a portion of the skull, the difference is that after a craniotomy the bone is replaced and after a craniectomy the bone is not immediately replaced.

Root Operation “Resection” This root operation would be selected when the physician removes all of a body part without replacement. When resection of an organ is completed, no portion of that specific organ is left behind.

Root Operation C: Extirpation The definition for the root operation Extirpation provided in the 2013 ICD-10-PCS Reference Manual is “Taking or cutting out solid matter from a body part.” The solid matter contained in the definition may be an abnormal byproduct of a biological function or a foreign body.
The following crosswalk between ICD-10-PCS to ICD-9-PCS is based based on the General Equivalence Mappings (GEMS) information:
The ICD-10 Procedure Coding System (ICD-10-PCS) is a catalog of procedural codes used by medical professionals for hospital inpatient healthcare settings. The Centers for Medicare and Medicaid Services (CMS) maintain the catalog in the U.S. releasing yearly updates.
To illustrate the point about skin incisions being required, the Winter 1993 issue of the CPT Assistant states the following about the anterior cranial fossa approach code (61580) that is frequently misused to report an endoscopic procedure:
The existing open (involving skin incisions) skull base surgery CPT codes were implemented in 1994, which was prior to skull base surgery being performed via an endoscopic endonasal approach (without skin incisions). The existing skull base codes are valued for an open procedure involving major skin incisions and soft tissue dissection. Endoscopic endonasal techniques were not in use prior to 1994 when the open skull base codes were introduced into CPT.
The adjacent tissue transfer codes (14xxx) are described by CPT as surgically freeing skin and subcutaneous tissue and/or fascia; therefore, these codes are also not appropriate for reporting a nasoseptal flap.
Currently, there are no other CPT codes to report a skull base procedure when performed endoscopically through an endonasal approach. Therefore, an unlisted procedure code must be reported.
The CPT Assistant, Spring 1993 describes the typical use of the secondary repair codes in two situations: 1) where a plastic/reconstructive surgeon performs the service, or 2) for repair of a postoperative cerebrospinal fluid leak.
The first situation occurs when a plastic/reconstructive surgeon performs reconstruction of a more extensive dura/surgical defect at the same operative session as skull base surgeons have removed the tumor and were unable to close the defect primarily. This situation, which may have been common in the early 1990's when these codes were created, is extremely rare in today's clinical practice. The closure performed at the time of the procedure is included in the global surgical package for the otolaryngologist or neurosurgeon when an intradural open definitive skull base resection code is used (e.g., 61601).
In an endoscopic endonasal procedure, a rhinotomy for access to the skull base is not performed. The definitive procedure codes presume an open approach as this was the standard in 1994 when the codes were written. Therefore, it is not appropriate to report an existing skull base code for an endoscopic endonasal procedure.
