When healthcare providers, billing specialists or RCM teams search for a reliable CPT code 93798 guide, they’re looking for clarity on how to bill, document, and get reimbursement for physician-supervised outpatient cardiac rehabilitation with continuous ECG monitoring. This guide will cover the code definition, key requirements, common pitfalls, and how leveraging an expert partner can help maximise reimbursement—while pointing you to the in-depth resource.

What is CPT 93798?
The code CPT Code 93798 sits within the “Other Cardiovascular Procedures” range printed by the American Medical Association (AMA).
Specifically, 93798 is defined as: “Physician services for outpatient cardiac rehabilitation; with continuous electrocardiographic (ECG) monitoring (per session).”
In simple terms: when a patient participates in a supervised cardiac rehab session with continuous ECG monitoring, the supervising physician’s service is captured by 93798.

Key Coding & Documentation Requirements
Here are major points any “CPT code 93798 guide” should highlight:
Continuous ...
... ECG Monitoring – The defining feature of 93798. Documentation must show the patient was under ECG monitoring for the session.

*Supervising Physician Availability – A physician (or qualified provider under supervision) must directly supervise the session. Some payers require immediate availability.

*Qualifying Diagnoses / Medical Necessity – Examples: myocardial infarction, coronary bypass, valve surgery, stable angina. Medicare policy lists specific ICD-10 codes that support medical necessity.

*Session Duration & Frequency – According to the American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR), a session billed as 93798 must monitor ECG for the entire session (for example 60 minutes) to qualify.

*Modifiers & Multi-Service Days – If on the same day the provider also did a separate evaluation/management (E/M) service, modifier -25 may be needed. If two cardiac rehab sessions occur on one day, coding separate entries (one 93798 plus one 93797) may apply.

*Payer Variations – Hospital-based outpatient CR programs may reimburse 93798 and 93797 at the same rate, but physician-based settings and private payers may differ.

Common Mistakes & How to Avoid Denials
Any solid “CPT code 93798 guide” will emphasise frequent pitfalls:
Using 93798 when ECG monitoring is not continuous (should use 93797 instead).

*Missing documentation of continuous ECG monitoring or physician supervision.

*Failing to attach the correct ICD-10 diagnosis codes that support medical necessity.

*Incorrect or missing modifier usage (leading to bundling or denied separate services).

*Not verifying payer-specific rules for cardiac rehab session limits, authorisations, and documentation.

To avoid these mistakes: maintain a checklist of the above requirements, conduct periodic internal audits, train your coding and billing staff, and align with your RCM team’s denial-prevention protocols.
