Stereotactic radiosurgery (SRS) is a non-invasive medical procedure that utilizes advanced technology to deliver high doses of radiation precisely to targeted areas within the cranial cavity. This technique is particularly effective for treating complex cranial lesions, which may include tumors or other abnormal growths in the brain. The procedure employs various forms of radiation, including particle beams, gamma rays, or linear accelerators, to ensure that the radiation is concentrated on the lesion while minimizing exposure to surrounding healthy tissue. The use of a rigid stereotactic frame is essential, as it stabilizes the patient's head in a fixed position, allowing for accurate targeting of the radiation beams. Prior to the treatment, detailed imaging studies such as three-dimensional MRI or CT scans are conducted to visualize the lesion and assess its characteristics, including its location and volume. This meticulous planning is crucial for determining the appropriate radiation dose and for evaluating the potential risks to adjacent structures. Stereotactic radiosurgery is typically performed in conjunction with a primary procedure, and the code for each additional complex cranial lesion treated is designated as CPT® Code 61799, which is reported separately in addition to the primary procedure code.

The procedure of stereotactic radiosurgery (SRS) is indicated for the treatment of various complex cranial lesions. These may include:
The procedure of stereotactic radiosurgery involves several critical steps to ensure precision and effectiveness. Each step is designed to maximize the accuracy of radiation delivery to the targeted lesion while minimizing damage to surrounding healthy tissue.
After the completion of the stereotactic radiosurgery, patients are typically monitored for a short period to ensure there are no immediate complications. Post-procedure care may include instructions on managing any potential side effects, such as fatigue or mild headaches. Patients are often advised to follow up with their healthcare provider for ongoing assessment of the treatment's effectiveness and to monitor for any changes in their condition. The recovery process is generally quick, as SRS is a non-invasive procedure, allowing patients to resume normal activities shortly after treatment.

GC | This service has been performed in part by a resident under the direction of a teaching physician | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service | 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. | 76 | Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | 78 | Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.) | 79 | Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.) | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | GW | Service not related to the hospice patient's terminal condition | LT | Left side (used to identify procedures performed on the left side of the body) | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure |
