Extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) are terms that refer to advanced medical procedures used to provide long-term support for patients with severe heart and lung dysfunction. These procedures typically last from three to ten days and involve the circulation of blood outside the body through an artificial lung, which oxygenates the blood before returning it to the patient's bloodstream. In the case of veno-venous (V-V) ECMO/ECLS, blood is drawn from a large central vein, oxygenated, and then returned to the venous system. This method is particularly useful for patients whose lungs are unable to provide adequate oxygenation. Conversely, veno-arterial (V-A) ECMO/ECLS involves drawing blood from a central vein and returning it to a major artery, which is beneficial for patients with both cardiac and respiratory failure. The initiation of ECMO/ECLS is a complex process that requires a thorough evaluation of the patient's condition, including various diagnostic tests such as laboratory analyses, imaging studies like X-rays, and echocardiograms. Additionally, a neurological assessment may be performed, especially in neonates. It is essential to obtain informed consent from the patient or their family prior to the procedure. The setup involves preparing the necessary equipment, including the ECMO pump, anticoagulation (ACT) machine, and associated tubing, as well as ensuring that the ECMO bed is ready. Medications and blood products are also procured to support the patient's needs during the procedure. Once all preparations are complete and the medical team is in position, cannulation of the vessels is performed, allowing for the commencement of ECMO/ECLS therapy. The initiation of V-V ECMO/ECLS can be performed by qualified healthcare professionals such as neonatologists, pediatric intensivists, surgeons, or interventional cardiologists, with continuous monitoring provided by a perfusion specialist around the clock. The specific CPT® code 33946 is designated for billing physician services related to the initiation of V-V ECMO/ECLS, while CPT® code 33947 is used for V-A ECMO/ECLS initiation.

Extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) are indicated for patients experiencing severe respiratory or cardiac failure that cannot be managed by conventional therapies. The following conditions may warrant the initiation of V-V ECMO/ECLS:
The initiation of veno-venous (V-V) ECMO/ECLS involves several critical procedural steps to ensure the safe and effective support of the patient’s respiratory function. The process begins with a comprehensive evaluation of the patient’s medical condition, which includes obtaining informed consent from the patient or their family. This is followed by a series of diagnostic tests, such as laboratory tests, imaging studies, and neurological evaluations, to assess the patient's suitability for ECMO therapy.
Following the initiation of V-V ECMO/ECLS, the patient requires continuous monitoring by a perfusion specialist to ensure the effectiveness of the therapy and to manage any potential complications. The medical team must regularly assess the patient's hemodynamic status, oxygenation levels, and overall response to the ECMO support. Adjustments to the ECMO settings may be necessary based on the patient's condition. Additionally, ongoing laboratory tests and imaging studies may be performed to evaluate the patient's progress and to make informed decisions regarding the continuation or modification of the ECMO therapy. The duration of ECMO support typically ranges from three to ten days, depending on the patient's recovery and underlying condition.

| 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). | 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. | 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). | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | CR | Catastrophe/disaster related | GC | This service has been performed in part by a resident under the direction of a teaching physician | GW | Service not related to the hospice patient's terminal condition | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
