The CPT® Code 93602 refers to the procedure known as intra-atrial recording, which is a diagnostic test used to assess the electrical activity within the atria of the heart. This procedure is particularly important for identifying conditions such as atrial flutter or atrial fibrillation, which may not be detectable through standard transthoracic electrocardiography (ECG). During the procedure, the physician obtains recordings from the atria, which are the upper chambers of the heart, to evaluate their electrical function. The process involves accessing the heart through veins, typically the femoral or jugular veins, where the skin is prepped, and the veins are punctured to insert sheaths. Using continuous fluoroscopic guidance, guidewires are carefully advanced into the heart, followed by the placement of catheters that are used to record the electrical activity. The recordings obtained are crucial for diagnosing arrhythmias and understanding the heart's electrical conduction system. After the procedure, the physician analyzes the recordings and generates a written report detailing the findings, which aids in determining the appropriate management for the patient’s condition.

The intra-atrial recording procedure (CPT® Code 93602) is indicated for the evaluation of specific cardiac conditions that may not be adequately assessed through non-invasive methods. The primary indications for this procedure include:
The intra-atrial recording procedure involves several critical steps to ensure accurate recordings of the heart's electrical activity. The steps are as follows:
After the intra-atrial recording procedure is completed, the patient may be monitored for any immediate complications related to the access site or the procedure itself. The physician will review the recordings and provide a detailed report, which may guide further management or treatment options for the patient. Patients are typically advised on any necessary follow-up appointments or additional testing that may be required based on the findings of the intra-atrial recording.

| 26 | Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number. | 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. | 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. | 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.) | GC | This service has been performed in part by a resident under the direction of a teaching physician | Q6 | Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
