How much does it cost to switch medical billing companies?

Budget for a one-time setup or implementation fee plus 30–90 days of overlap where you pay both the old and new vendor on aging claims. Ongoing pricing is usually 4–9% of collections, so a cardiology practice collecting $600,000 a year runs $24,000–$54,000 annually. Get setup, per-claim, and reporting fees itemized in writing before signing.

How long does it take to switch cardiology billing companies?

Credentialing, clearinghouse re-enrollment, and payer EDI setup typically drive a 30–60 day migration. In a clean switch, A/R days hold under 45 and cash flow smooths inside 60 days. Watch the share of receivables past 90 days weekly — a top-quartile operation keeps it under 15%. If that number climbs past 20%, escalate to your named account owner immediately.

What percentage of collections should a cardiology billing company charge?

Most US practices pay 4–9% of net collections, with cardiology often landing mid-range because echo, stress testing, and cath lab claims (93306, 93458) carry heavier documentation and modifier requirements than primary care. Flat per-claim pricing exists but shifts denial risk to you. Compare all-in cost, not headline rate, and confirm the 85%+ denial resubmit benchmark is contractual.

What is a good A/R days number for a cardiology practice?

Under 45 days is the benchmark for a well-run outsourced RCM operation per MGMA 2024 practice-operations data, with less than 15% of total receivables aging past 90 days. If your current biller sits at 55–70 days, roughly two extra weeks of cardiology revenue is tied up in unworked claims — often $40,000–$80,000 for a mid-size group.

How do I compare medical billing companies without sitting through sales pitches?

Ask every candidate the same three questions on the first call: quoted A/R days, denial resubmit rate, and percentage of receivables over 90 days — all specific to your specialty, not company-wide averages. A partner without specialty-level data has given you the answer. Through medoutbound, matched and vetted billing partners reach out within one business day, with no obligation to proceed.

Switching Cardiology Billers: 30-day Cost & 90-day A/R Impact

TL;DR

Switching cardiology billers typically costs 30–90 days of parallel-run overhead plus any one-time setup fee, on top of outsourced RCM pricing that generally runs 4–9% of collections. For a solo cardiologist collecting $600,000–$900,000 annually, that fee alone is roughly $24,000–$81,000. A well-run migration holds A/R under 45 days, keeps under 15% of receivables past 90 days, and sustains an 85%+ denial resubmit rate. Ask candidates to quote those three numbers against your actual CPT profile — 93000, 93306, 93458 — before you sign, and expect cash flow to smooth inside 60 days.

Switching medical billing partners feels risky because most practice managers have never seen a clean one. When the migration is planned well, A/R holds and cash-flow smooths out inside 60 days. Compare partners without a sales pitch — matched shops reach out within one business day.

The migration numbers that actually matter

Two metrics tell you whether a switch is going smoothly or quietly bleeding cash. Watch these; the rest is noise.

If a candidate partner won't quote these three by specialty in the first call, they don't have the data — which is the answer.

Every practice that puts off a switch for "risk" ends up doing it under duress. Planned migrations preserve A/R; forced ones don't.

Three fits to check on a demo call

Do they know your specialty by CPT profile, not by name? Cardiology and family practice claim mixes look nothing alike; a partner who can't discuss modifier patterns will learn on your revenue.
Do you get one owner or a ticket queue? A named contact shortens rework loops from days to hours.
What's included in the quote, all-in? Setup, per-claim fees, and reporting line items should be spelled out — surprise invoices are the #1 partner complaint on peer forums.

CPT/ICD Codes Cardiology Billers Must Master

Below is a working reference of codes cardiology billers touch most often, alongside the denial triggers that show up first in a partner review. Fee-schedule numbers are national Medicare Physician Fee Schedule (2024–2025) ballparks; actual reimbursement varies by Medicare Administrative Contractor jurisdiction and payer contract.

CPT 93454 · Coronary Angiography without Left Heart Catheterization

National Medicare payment ballpark: ~$450–600 (2024–2025 PFS, national physician component only; facility rates differ substantially, MAC-dependent). Denial triggers cluster around missing modifier -26 for the professional-only component and imaging-appropriateness edits when the referring diagnosis is unspecified. Cardiology billers must know when to reach for 93458 instead (adds LV angiography).

CPT 93458 · Coronary Angiography with Left Ventricular Angiography

National Medicare payment ballpark: ~$550–750 (2024–2025 PFS, MAC-dependent). Higher-value sibling of 93454. Common billing error: coding 93454 + a separate LV angiography code when the bundled 93458 is the correct single-code descriptor. Unbundling triggers post-payment audits with claw-back risk, so partner selection should probe how the biller handles the 93454 vs 93458 decision.

CPT 92928 · Percutaneous Coronary Intervention, Single Vessel

National Medicare payment ballpark: ~$1,200–1,800 for the professional component (2024–2025 PFS, MAC-dependent). Multi-vessel add-on codes (92929) carry separate payment rules and modifier-59 requirements. Denials often trace back to insufficient documentation of vessel-specific medical necessity or missing prior authorization for elective indications. Ask how a prospective biller structures pre-service authorization tracking.

CPT 78452 · Myocardial Perfusion Imaging, SPECT, Multiple Studies

National Medicare payment ballpark: ~$220–340 for the professional component (2024–2025 PFS, MAC-dependent). Requires supervision level documentation, appropriate-use criteria attestation (CMS AUC program), and specific stress-agent documentation. Common denial: missing the imaging appropriateness modifier under the AUC program. Confirm the billing partner tracks AUC ordering compliance.
