CPT 93654 covers a comprehensive electrophysiology study to evaluate and treat life-threatening ventricular tachycardia (VT), a dangerous abnormal heart rhythm originating in the lower chambers of the heart. This procedure involves mapping electrical pathways and attempting to induce and terminate the arrhythmia to guide treatment.
This calculator gives a typical-case estimate using standard Medicare modifier rules. Actual payment depends on payer policies, documentation, code-specific CMS status indicators, and locality. Verify before billing.

Billing tips
Document all attempted induction protocols including number of extrastimuli, drive cycle lengths, and sites of stimulation (RV apex, RVOT, multiple sites)
Impact: Missing induction documentation is the #1 reason for downcoding to 93620; can result in $600+ loss per case
93654 includes diagnostic EP study components; do not separately bill 93619, 93620, or 93621 on the same date of service
Impact: Prevents automatic denial and recoupment; these codes are bundled per NCCI edits
If ablation is performed during the same session, bill 93654 with ablation code 93656; both are separately reimbursable
Impact: Ensures full payment for both diagnostic evaluation ($953.57) and ablation procedure; combined reimbursement exceeds $2,000
Clearly document His bundle recording and both right and left ventricular pacing/recording to support comprehensive nature of study
Impact: Differentiation from limited studies prevents downcoding; maintains full RVU value of 29.48
Use time-based documentation showing total procedure time, fluoroscopy time, and duration of each component for medical necessity support
Impact: Strengthens medical necessity defense in audits; average procedure time should be 90-180 minutes for comprehensive VT evaluation
Bill in facility setting when performed in hospital; note that facility and non-facility rates are identical at $953.57 for 93654
Impact: No reimbursement difference but correct place of service code (22 or 24) is required to avoid denials
