Intra-atrial pacing
CPT code 93610 covers intra-atrial pacing, a diagnostic heart procedure where a cardiologist temporarily paces the heart from inside the upper chambers (atria) to evaluate electrical function or induce abnormal heart rhythms for diagnostic purposes.
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
Bill 93610 separately from comprehensive EP study codes (93619-93622) only when pacing is performed independently, not as integral component of mapping/ablation
Impact: Prevents $152.03 denial due to bundling; most payers consider intra-atrial pacing included in comprehensive EP studies
Document exact pacing protocol including cycle lengths, number of stimuli, and specific diagnostic purpose (e.g., SNRT, AVNRT induction)
Impact: Reduces audit risk and supports medical necessity; inadequate documentation causes 30-40% of payment delays
Verify facility versus non-facility status as both rates are identical at $152.03 for 2025, eliminating place-of-service payment differential
Impact: Eliminates concern about POS coding errors that typically affect reimbursement by 15-30% for other codes
When performed with diagnostic EP study, ensure separate dictation clearly distinguishing intra-atrial pacing from routine His bundle recordings
Impact: Supports modifier 59 use when appropriate; can preserve additional $152.03 when medically necessary and distinct
Bill on same claim as venous access codes (36000-36011) only if separate access site used specifically for pacing catheter
Impact: Avoids bundling edits; however, most payers include venous access in EP procedure payment, risking $50-$100 denial
For Medicare patients, verify LCD coverage requirements specific to electrophysiology studies in your MAC jurisdiction
Impact: Prevents denial of entire $152.03 payment; coverage varies by MAC with some requiring pre-authorization for non-emergent cases
