Coronary thrombolysis is a medical procedure aimed at dissolving blood clots that obstruct coronary arteries, which can lead to serious cardiovascular events such as heart attacks. The procedure described by CPT® Code 92975 involves the direct administration of a thrombolytic agent through an intracoronary infusion. This method is typically performed when a patient presents with acute coronary syndrome, characterized by symptoms such as chest pain, shortness of breath, or other signs of myocardial ischemia. The procedure begins with the insertion of a catheter from a major access vessel, commonly the femoral or brachial artery, which is then navigated to the site of the thrombus within the coronary artery. Once the catheter is positioned correctly, a thrombolytic agent—such as streptokinase, alteplase, or reteplase—is infused directly into the artery to facilitate the breakdown of the clot. Following the infusion, contrast material is injected to conduct a selective coronary angiography, allowing the physician to visualize the artery and confirm that the thrombus has been effectively dissolved and that blood flow is restored. This procedure is critical in managing acute coronary events and improving patient outcomes by restoring perfusion to the heart muscle.

Coronary thrombolysis by intracoronary infusion (CPT® Code 92975) is indicated for patients experiencing acute coronary syndrome, which may manifest as:
The procedure for coronary thrombolysis via intracoronary infusion involves several critical steps:
Following the intracoronary thrombolysis procedure, patients are typically monitored for any complications, such as bleeding at the access site or signs of re-occlusion of the artery. Continuous cardiac monitoring is essential to assess the patient's heart function and detect any arrhythmias. Patients may also require additional medications, such as antiplatelet agents, to prevent further clot formation. The expected recovery period can vary based on the individual patient's condition and response to the procedure, but close follow-up is necessary to ensure optimal outcomes and manage any potential complications.

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). | 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. | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | LD | Left anterior descending coronary artery | RC | Right coronary artery | 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 |
