Accurate use of Cardioversion CPT Codes is essential for correct reimbursement, proper documentation, and compliance. Cardioversion — the medical procedure used to restore a normal heart rhythm — can be performed in synchronized and unsynchronized ways.
In this guide, we’ll break down these procedures and help you understand exactly which CPT codes to use in each case, avoid common errors, and stay updated on any code changes.
What Is Cardioversion?
Cardioversion is a medical procedure designed to restore a patient’s heart to a normal sinus rhythm.
It is commonly used to treat:
Atrial fibrillation (AFib)
Atrial flutter
Supraventricular tachycardia (SVT)
Other arrhythmias
Depending on the urgency and method, cardioversion may be synchronized or unsynchronized.
Understanding Cardioversion CPT Codes
Correct coding for cardioversion ensures that procedures are reimbursed properly and helps maintain accurate clinical documentation. Misuse of cardioversion CPT codes may lead to denied claims or compliance issues.
Synchronized Cardioversion CPT Codes
What Is Synchronized Cardioversion?
Synchronized cardioversion delivers an electrical shock precisely timed (synchronized) with the patient’s heart rhythm.
It is typically an elective procedure, performed in a controlled setting, with sedation if necessary.
Common Indications:
Stable atrial fibrillation
Atrial flutter
SVT that is not responsive to medications
CPT Code:
Documentation Tips:
Clearly document synchronization with R-wave
Specify sedation if used
Record indications for cardioversion
Include number of shocks delivered
Unsynchronized Cardioversion CPT Codes
What Is Unsynchronized Cardioversion?
Unsynchronized cardioversion is often referred to as defibrillation.
Shocks are delivered immediately without regard to heart rhythm timing.
Used primarily in emergency situations (e.g., pulseless ventricular tachycardia or ventricular fibrillation).
CPT Code:
Note: Emergency defibrillation in hospital settings is often included as part of critical care, ACLS, or emergency department services — it may not always be reported separately using CPT 92960 or 92961. Always follow payer guidelines.
Cheat Sheet: Cardioversion CPT Codes at a Glance
Common Coding Mistakes and How to Avoid Them
Using 92960 for emergency defibrillation — should be captured under critical care/E&M when appropriate.
Failing to document whether synchronization was performed.
Not recording indications or sedation details.
Using 92961 when no internal device is involved.
How to Stay Updated on Cardioversion CPT Codes
Refer to AMA CPT Updates annually.
Subscribe to payer bulletins and coding newsletters.
Utilize resources from organizations such as AAPC or AHIMA.
Attend coding webinars for cardiology procedures.
Conclusion
Accurate coding for cardioversion requires a clear understanding of the differences between synchronized and unsynchronized procedures, proper use of cardioversion CPT codes, and careful documentation. By applying these best practices, you can help ensure timely reimbursement, compliance, and quality reporting.
