CPT® Code 33285

The CPT® Code 33285 refers to the procedure of inserting a subcutaneous cardiac rhythm monitor (ICM), which is a device designed to continuously monitor the heart's rhythm over an extended period. This device functions similarly to a long-term Holter monitor, specifically aimed at detecting episodes of atrial fibrillation. The ICM utilizes automated algorithms to identify abnormal QRS signals, which are indicative of irregular heart rhythms. One of the key features of this device is its ability to transmit patient data wirelessly to healthcare providers, allowing for remote monitoring and timely intervention if necessary. The use of a subcutaneous cardiac rhythm monitor is particularly indicated for patients who present with transient symptoms that may suggest a cardiogenic origin, such as dizziness, syncope (loss of consciousness), chest pain, and palpitations. These symptoms may place patients at a higher risk for serious conditions like atrial fibrillation, stroke, or heart failure. The procedure not only involves the physical insertion of the device but also includes programming it to ensure accurate data collection and performance verification, making it a comprehensive approach to cardiac monitoring.
