CPT 92960: Cardioversion Coding & Billing Guide [2026]

Getting paid for cardioversion should be simple. The doctor shocks the heart, the rhythm resets, and you bill the code. However, payers regularly deny claims based on medical necessity, modifier issues, or claims that the procedure is bundled in with other services.

For the CPT code 92960, new rules are now in effect for 2026. For example, if you don't submit one of two required diagnosis codes or you fail to subtract the sedation time from the total time, you may lose some of your revenues.

This guide has been developed to provide you with the exact steps to bill the cardioversion procedure using CPT code 92960, to successfully pass audits, and to maintain a healthy revenue cycle.

What is CPT Code 92960?

First, we will review the official definition, so you can use this wording when submitting appeals to a payer who has denied a claim.

CPT 92960: Cardioversion, elective, electrical conversion of arrhythmia; external.

In plain English, the definition for CPT 92960 states:

This CPT code is used to report an external procedure, i.e., the physician applies pads or paddles to the patient's chest and uses an electrical shock to correct an abnormal heart rhythm (such as Atrial Fibrillation).

Important considerations when billing CPT 92960:

External only: The pads must be applied to the patient's skin.

Elective: The procedure was generally scheduled.

Electrical:The use of drugs (pharmacologic cardioversion) does not meet the requirements of this CPT code.

The Big Mix-Up: 92960 vs. 92961

Coding personnel generally do not understand this distinction. This is a matter of physical location, and not solely an issue of complexity.

Rule of Thumb:

Was the physician required to make an incision into the chest?

• Yes: Charge 92961.
• No: Charge CPT Code 92960.

If you have a difficult time differentiating between these operative note types, you can use our medical coding services to assess your documentation and assist in preventing undercoding.

Is It an Emergency or Elective?

This is when the code becomes difficult to interpret. Cardioversion can be performed in the Emergency Department by doctors who believe that their patients are unstable.

Can you bill 92960 in the ER?

Yes. Although the code description states "elective" the AMA and CMS allow the use of CPT code 92960 for emergency defibrillation when a patient has an identifiable arrhythmia such as A-Fib or SVT.

The Trap:

You cannot charge 92960 during cardiac arrest (CPR). If the patient has cardiac arrest (flatlines), the physician will administer a shock as a part of CPR; however, the services rendered during CPR are contained within the critical care codes (99291, 99292) or CPR code (92950). Only bill 92960 if the patient has a distinct, shockable rhythm and the doctor performs a dedicated cardioversion.

2026 Reimbursement & RVUs

Money Matters. Medicare adjusts the Relative Value Units (RVUs) every year. The 2026 annual adjustment focuses on the "work RVU," which is the amount of money for the doctor’s time and skills.

• Work RVU (Approximate): 1.80 – 2.00 range (Always check the final MPFS release).
• Malpractice RVU: ~0.15.
• Global Period: 0 Days.

What this means:

The 0 day global period allows you to bill for the procedure today. This eliminates the need to wait until the post op window closes before billing additional services. However, because the global period is 0 days, you are unable to add in bundled follow up care to this code.

If you find payments falling below these guidelines, it might be time to audit your contracts. Our medical accounts receivable services team often finds that payers use outdated fee schedules to underpay these claims.

Approved ICD-10 Codes (Medical Necessity)

Payers will auto-deny CPT code 92960 if you link it to a generic code like "Chest Pain" (R07.9). You must prove the patient had an arrhythmia that required a shock.

Here are the most common medically necessary diagnoses for 2026:

• I48.0: Paroxysmal atrial fibrillation
• I48.11: Longstanding persistent atrial fibrillation
• I48.19: Other persistent atrial fibrillation
• I48.20: Chronic atrial fibrillation, unspecified
• I47.1: Supraventricular tachycardia (SVT)
• I49.9: Cardiac arrhythmia, unspecified (Use sparingly; payers hate unspecified codes).

Documentation Tip:

Your provider must document why the shock was necessary. A note saying "Patient shocked" is not enough. The note needs to say: "Patient in rapid A-Fib with hemodynamic instability. Decision made to perform synchronized cardioversion."

Correct Modifiers for CPT 92960

Modifiers give the payer details concerning the service provided at the session. There is no faster way to receive a denial than use the wrong modifier.

1. Modifier 25 (Significant, Separately Identifiable E/M)

Can you bill an office visit (99202–99215) on the same day as cardioversion?

Only when the doctor's decision to perform the procedure occurs during the visit can you bill an office visit.

• Example: Patient comes in for a check-up. Doctor diagnoses A-Fib and elects to shock immediately.
• Bill: 99214-25 AND 92960: When the patient was scheduled for the shock, you cannot bill the office visit.

2. Modifier 59 (Distinct Procedural Service)

If the doctor is going to provide another procedure on the same day which would normally be included with the procedure being performed, you will want to add the modifier 59.

• Example: The doctor completes a diagnostic cardiac catheterization, and then the patient develops A-Fib, and requires a shock.
• Bill: Cardiac catheterization code AND 92960-59.

3. Modifier 76 (Repeat Procedure)

There are times when one shock will not be enough. If the doctor delivers a shock to the patient, waits, and then delivers another shock in a different session (it is rare to see repeat cardioversions; however, it is common with other types of procedures), you may need to use this modifier.

• Note: Multiple shocks delivered in a single session typically warrant billing one unit of the CPT code 92960. Do not bill two units of 92960 simply because you pushed the button two times.

Can You Bill for Sedation?

Cardioversion may be painful. The patient usually gets sedated by the doctor.

The Rule:

CPT Code 92960 includes sedation but you are allowed to charge separately for it.

The Codes:

• 99152: Moderate sedation (first 15 minutes) provided by the same physician as the cardioversion.
• 99153: Every 15 minutes of moderate sedation after the first 15 minutes.

The Catch:

In order to charge 99152 for sedation, there has to be a trained "observer" (like a nurse) documented as being present during the procedure to observe the patient. There cannot be an independent observer documented then you will not get to charge for sedation.

You might find it too difficult to manage your sedation charges and that is why we at Human Medical Billing have experience with un-bundling these charged services so you can maximize how much money you earn.

Common Denial Reasons (And How to Fix Them)

In our denial management services we have reviewed thousands of denied claims for 92960. We found that the top three reasons that payers deny 92960 claims in 2025 are as follows:

1. Missing ECG Strips

The payer wants proof. They want to see the "Before" strip (showing A-Fib) and the "After" strip (showing Sinus Rhythm). If you do not attach these or have them on file, they will claw back the money.

2. Wrong Service Date

When a patient is admitted to the Emergency Department at 11:50PM and receives the cardioversion at 12:10AM, be sure to document the date of the service to be the date of the cardioversion, NOT the date of admission.

3. Provider Eligibility

Occasionally a mid-level provider (PA or NP) provides cardioversion without a doctor being present in the room. Some commercial insurance companies have restrictions against such. Our medical credentialing services verify that all PAs and NPs performing cardioversions are registered, approved, and have the authority to provide cardioversions to patients BEFORE they treat the first patient.

Final Steps for a Clean Claim

Cardioversion is extremely specific when it comes to billing. You will need the right diagnosis along with your rhythm strip(s), and you will need the correct modifiers to bill this procedure correctly.

Before you submit your claim, check off each item in the checklist below:

• Is it CPT code 92960 (External) or 92961 (Internal)?
• Did you attach an arrhythmia diagnosis (I48.x)?
• If you billed an E/M code, did you add modifier -25?
• Did you capture the sedation start and stop times?

Following these guidelines will minimize your number of denied claims as well as decrease the amount of time your office spends waiting for payment from Medicare.

While the regulations for 2026 are more stringent than those previously used, they can be managed by following the same steps as above. If you would rather spend less time worrying about these updates and more time focused on providing the best possible care to your patients, consider working with Human Medical Billing.
