The CPT® Code 33269 refers to the thoracoscopic exclusion of the left atrial appendage (LAA), a procedure that is particularly relevant for patients diagnosed with non-valvular atrial fibrillation (NVAF) who are at an elevated risk for thrombus formation or stroke, especially when oral anticoagulation therapy is not a viable option. The LAA is a small, pouch-like structure located in the left atrium of the heart, which can be a site for blood clots to form, potentially leading to serious complications such as stroke. The procedure aims to completely close off or remove the LAA to mitigate this risk. The LAA exhibits considerable anatomical variability, categorized into four distinct morphological groups: the 'chicken wing' type, characterized by a bend in the proximal end of the dominant lobe; the 'windsock' type, which features a long main lobe exceeding 4 cm; the 'cauliflower' type, which has a limited length of less than 4 cm and lacks forked lobes; and the 'cactus' type, which has a dominant central lobe with secondary extension lobes. The unique size and shape of the LAA, along with factors such as the pressure or loading status of the heart and whether the patient is in sinus rhythm or atrial fibrillation, play a crucial role in determining the most appropriate closure method. In practice, the thoracoscopic approach typically involves the deployment of a clip under general anesthesia. This minimally invasive technique requires the placement of thoracoscopic ports between the ribs on the left side of the chest, allowing for the insertion of an endoscope. The clip is then carefully positioned at the base of the LAA, with its correct placement verified through transesophageal echocardiography, ensuring the effectiveness of the procedure in preventing potential thrombus formation.

The thoracoscopic exclusion of the left atrial appendage (CPT® Code 33269) is indicated for patients with specific conditions and risk factors. The primary indications for this procedure include:
The procedure for thoracoscopic exclusion of the left atrial appendage involves several critical steps, which are detailed as follows:
Following the thoracoscopic exclusion of the left atrial appendage, patients typically require monitoring in a recovery area until the effects of anesthesia wear off. Post-procedure care may include pain management, monitoring for any complications, and ensuring the patient is stable before discharge. Patients may also need follow-up appointments to assess recovery and the effectiveness of the procedure. It is essential to provide education on signs of potential complications, such as bleeding or infection, and to discuss any necessary lifestyle modifications or additional treatments that may be required following the procedure.

| AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | 22 | Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service. | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 53 | Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use). | 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. | 62 | Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate. | 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.) | 80 | Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s). | 81 | Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number. | 82 | Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s). | CR | Catastrophe/disaster related | 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) | Q0 | Investigational clinical service provided in a clinical research study that is in an approved clinical research study | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
