What 93291 covers
This service evaluates an implanted subcutaneous cardiac rhythm monitor, often called an implantable loop recorder, during an in-person device check. Device clinic staff retrieve stored information, and a physician or other qualified practitioner reviews and interprets recorded events and reports the findings. These monitors may be used to investigate intermittent symptoms such as syncope or palpitations when rhythm information is needed over time.
Report 93291 for the in-person interrogation and analysis of the subcutaneous monitor, not simply for changing its programmed settings. The record should identify the device and support the in-person evaluation, data review, interpretation, and report. Billing without a modifier represents the global service; modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service, including equipment and staff. When multiple cardiovascular diagnostic procedures are performed, the CMS multiple-procedure reduction applies to this code’s technical component.
