CPT Code 33285: Insertion of a Subcutaneous Cardiac Rhythm Monitor

Read more on the documentation requirements and billing guidelines of CPT code 33285 for accurate coding and billing.

What is CPT 33285?

CPT code 33285 pertains to the procedure of placing an insertable cardiac monitor, specifically a subcutaneous cardiac rhythm monitor, to continuously track heart activity for irregularities or cardiac arrhythmias. This extended cardiac monitoring solution provides an alternative to continuous inpatient cardiac telemetry and continuous inpatient ECG monitoring for patients requiring long-term cardiac surveillance.

Unlike mobile cardiac outpatient telemetry systems that require external devices, the subcutaneous monitor offers seamless extended cardiac monitoring without the limitations of traditional monitoring periods. The device provides accessible ECG data storage that can be transmitted to a central monitoring station for comprehensive analysis.

During the procedure, the device is programmed with optimal permanent programmed values tailored to the patient's specific cardiac monitoring needs. This approach offers advantages over mobile cardiac telemetry systems by providing continuous, uninterrupted monitoring without patient compliance concerns associated with external devices.
