Billing tips

Document all components: comprehensive mapping (at minimum right atrial, His bundle, RV, and CS recordings), induction attempts, pacing maneuvers from at least two sites, and any ablation performed
Impact: Missing documentation of any required component can result in complete denial of $791.20 or downcoding to simpler EP study codes worth $300-500 less
Do not separately bill ablation code 93656 when performed during the same session as 93653—ablation is included in comprehensive EP evaluation with treatment
Impact: Unbundling will trigger denial of 93656 ($1,200+ code) and potential audit; 93653 already includes treatment component
Ensure documentation specifies SVT mechanism identified (AVNRT, AVRT, atrial tachycardia) and response to treatment before claiming this code
Impact: Vague documentation may result in downcoding to diagnostic-only code 93620 ($550) representing 30% revenue loss
Bill only once per session regardless of number of SVT foci treated or ablation lesions created during that single procedure
Impact: Multiple units will be denied; comprehensive nature of code already accounts for complexity
When performed in facility setting, verify proper place of service code (22 for outpatient hospital, 24 for ASC) as both settings reimburse at $791.20
Impact: Incorrect POS may delay payment or trigger audit review
If diagnostic study only is performed without treatment attempt (patient wishes to defer or contraindication identified), bill 93620 instead of 93653
Impact: Using 93653 without treatment component documented will result in denial or request for refund upon audit

Frequently asked questions

What is the Medicare reimbursement rate for CPT 93653 in 2025?

The 2025 Medicare national average reimbursement for CPT 93653 is $791.20 for both facility and non-facility settings. This is based on 24.46 total RVUs (15 work RVU + 6.08 PE RVU + 3.38 MP RVU) multiplied by the 2025 conversion factor of 32.3465.

Can I bill CPT 93653 and 93656 together for SVT ablation?

No, you should not bill 93653 and 93656 together. CPT 93653 is a comprehensive code that includes both the electrophysiology evaluation and treatment (ablation) of SVT. Billing both codes together constitutes unbundling and will result in denial of the separately billed ablation code.

What is the difference between CPT 93653 and 93620?

CPT 93653 is a comprehensive EP evaluation with treatment of SVT, including ablation when performed, while 93620 is a comprehensive EP evaluation without treatment/ablation. Use 93653 when you perform diagnostic evaluation and therapeutic intervention (ablation) in the same session; use 93620 for diagnostic study only without treatment.

How many RVUs is CPT code 93653 worth?

CPT 93653 has 24.46 total RVUs in 2025, broken down as: 15 work RVUs, 6.08 practice expense RVUs, and 3.38 malpractice RVUs. This makes it one of the highest-valued electrophysiology procedure codes.

What documentation is required to bill CPT 93653?

Documentation must include: comprehensive intracardiac mapping from multiple sites (minimum RA, His, RV, CS), pacing from at least 2 sites, induction attempts, specific SVT mechanism identified, ablation details if performed, post-ablation testing results, and medical necessity justification. Missing any key element can result in denial or downcoding.

Can CPT 93653 be billed bilaterally or with multiple units?

No, CPT 93653 should only be billed as one unit per session regardless of how many SVT foci are treated or how many ablation lesions are created. The comprehensive nature of the code accounts for all work performed during that procedural session. Billing multiple units will result in denial.

Who can perform and bill for CPT 93653?

CPT 93653 should only be performed and billed by physicians who are board-certified in cardiology with advanced fellowship training and certification in clinical cardiac electrophysiology. The physician must personally perform the comprehensive evaluation, mapping, and any therapeutic intervention, not just supervise.
