Effective Holter and Event Monitor reimbursement in Cardiology Billing

Cardiology practices are involved with several medical equipment and devices that are used for patient treatment. Among these devices, Holter and event monitors are two major technologies used by cardiologists. A Holter monitor is a small, wearable, battery-powered device that is used to record the heart’s electrical activity. Event monitoring includes coding and billing for long-term outpatient cardiac rhythm tracking. It is activated during symptoms or automatically by the device. Both Holter and event monitoring are billed under specific CPT codes in the cardiology billing process. The application of the codes depends on the type of monitoring, duration, and whether the interpretation is included. For an effective reimbursement of both Holter and event monitoring, it is important to know the correct application of coding and billing methods.

Understanding the CPT codes for enhanced cardiology billing

Holter monitoring

In case of Holter monitoring, CPT codes 93224-93227 are used for recording, analysis, and interpretation of services. Mentioned below is the breakdown of the relevant codes:

• 93224 - This code is used for the application, removal, and analysis of a Holter monitor for up to 48 hours. It is used when a single entity performs all technical and professional components, usually inside a physician’s office.
• 93225 - This code is applicable to 12-lead Holter monitoring with application, removal, and analysis, also for up to 48 hours. It includes medical services like patient education, recording, and disconnection. There is inclusion of technical components, and the code is used when a physician or facility only performs the recording.
• 93226 and 93227 – These codes are less commonly used for variations for extended Holter monitoring beyond 48 hours, requiring specific payer guidelines. CPT 93226 is used for the technical component of Holter monitoring, while CPT 93227 applies to the professional component.

Event monitoring

The primary CPT codes applicable for event monitoring include:

• 93268 – This is a global code which covers the following:

• Complete service including patient education
• Device supply
• 24-hour attendance
• Transmission receipts
• Final physician review and interpretation

This code must be billed only when the cardiology practice performs every component of the service. It is used for external, or auto-activated electrocardiographic (ECG) rhythm monitoring. This monitoring includes a memory loop along with a remote download capability for up to 30 days.

• 93270 – This code is applied for the recording, connection, and disconnection of an external and patient-activated cardiac monitor. It is used to bill the technical component that includes both patient instruction and disconnection. The patient must send at least one transmission for this code to be reportable. It is widely used for event monitoring, ambulatory ECG monitoring, and remote monitoring for up to 30 days.

• 93271 – This involves the use of an external ECG event monitor worn for up to 30 days to record heart rhythm activity. The device can be activated by the patient during symptoms and may also automatically detect abnormal rhythms. It includes memory loop recording, remote data transmission, continuous 24-hour monitoring, and professional analysis of the transmitted cardiac data. While 93270 covers the hookup and recording aspect, 93271 covers the monitoring, receipt of transmission, and analysis.

What are the key challenges?

Holter monitoring

1. Incorrect selection of codes – Claim denials often occur due to the incorrect application of the code 93224, when the practice only performed part of the service. Selecting the wrong code based on monitoring duration, type of monitor, and global or split components are the major reasons behind denials.
2. Medical necessity – The lack of symptom documentation (syncope, palpitations), that are essential to justify the test, leads to claim denials. Claims may also be denied if the diagnosis codes are vague or non-covered. Some of the common examples include:

• Using unspecified chest pain without arrhythmia suspicion
• Screening diagnoses without symptoms

3. Date of service (DOS) – Cardiology billing complications increase because of the chances of hook-up and delayed interpretation. It is recommended to use the date of physician review as the DOS for 93227. The payer policies differ on which DOS to apply, when claims become billable, and whether all components must be completed first.

Event monitoring

1. Lack of medical necessity - An event monitor was ordered for a patient with intermittent dizziness and submitted under ICD-10 code R42 (dizziness and giddiness). Documentation failed to demonstrate that a standard Holter monitor had been attempted, considered inadequate, or unlikely to capture symptoms due to their infrequent occurrence.
2. Confusion between event and other monitoring services – One of the major reasons behind claim denials in event monitoring is the incorrect selection of CPT codes. Event monitoring is often confused with Holter monitoring, mobile cardiac telemetry (MCT), and implantable loop recorders. Cardiologists often bill telemetry codes instead of event monitor codes. The incorrect application of global services and duration codes often results in claim denials and audits.

Addressing these challenges is a big task, often difficult for the in-house billing teams. This is when the outsourced healthcare billing companies offer expert solutions in transforming the challenges into profits, with their experienced and trained staff.

Outsourcing as the best option for enhanced cardiology billing
