The CPT® Code 61330 refers to the procedure known as "Decompression of orbit only, transcranial approach." This surgical intervention is specifically designed to relieve pressure within the orbit, which is the bony cavity that houses the eye. The transcranial approach involves accessing the orbit through the skull, typically by removing a portion of the frontal bone. This method allows surgeons to reach the superomedial aspect of the orbit, which is crucial for addressing various lesions or defects located at the orbital apex, optic canal, or those that may involve both the orbit and adjacent intracranial structures. The procedure is characterized by a bicoronal incision, which is made across the scalp, enabling the reflection of the scalp to expose the underlying bone. The careful placement of burr holes and the use of a bone saw facilitate the removal of the frontal bone while preserving the orbital rim, allowing for adequate access to the affected areas. Throughout the procedure, meticulous attention is given to the dura mater, the protective covering of the brain, to prevent injury and ensure proper reconstruction of the orbital structures post-operation. This comprehensive approach is essential for alleviating pressure on critical ocular components, including the eye and optic nerve, thereby restoring function and alleviating symptoms associated with orbital compression.

The procedure coded as CPT® 61330 is indicated for various conditions that necessitate the decompression of the orbit. These indications may include:
The procedure for CPT® 61330 involves several critical steps to ensure effective decompression of the orbit. The steps are as follows:
Post-procedure care following CPT® 61330 involves monitoring for any complications and ensuring proper recovery. Patients may require observation for signs of infection, bleeding, or neurological deficits. Pain management is typically addressed, and follow-up appointments are scheduled to assess healing and the success of the decompression. Rehabilitation may be necessary depending on the extent of the procedure and the underlying condition being treated. Patients are advised on activity restrictions to promote healing and prevent complications during the recovery phase.

| 50 | Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 58 | Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78. | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | 80 | Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s). | GC | This service has been performed in part by a resident under the direction of a teaching physician | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) |
