Cardiology Medical Billing Services
Cardiology claims mix high-frequency office visits with high-dollar diagnostic and interventional procedures — and payers scrutinize both closely. Flint RCM's cardiology accounts are staffed by coders fluent in the specialty's CPT ranges, bundling edits, and prior authorization requirements.
Specialty-specific pitfalls we watch for.
- Bundling edits between same-day diagnostic tests (echo, stress tests, EKGs) that trigger denials without correct modifier use
- Modifier −25 disputes when an E/M visit and a procedure happen on the same day — a leading cause of cardiology denials
- Prior authorization requirements for cardiac catheterization, nuclear stress testing, and elective interventional procedures
- Add-on code sequencing errors on interventional and structural heart procedures
- Device and implant documentation gaps that trigger high-dollar claim holds
- Coders trained specifically on CPT 93000–93799 (diagnostic) and 92920–92944 (interventional) code sets
- Authorization verification completed before elective procedures are scheduled, not after
- Modifier −25 and −59 documentation review built into pre-submission claim scrubbing
- Denial pattern tracking specific to bundling edits, with root-cause reporting back to your practice
What makes Cardiology coding different.
- CPT 93000–93799 (EKG, echocardiography, stress testing) paired correctly with the same-day E/M visit using modifier -25 where applicable
- CPT 92920–92944 (interventional/catheterization procedures) coded to the exact vessel and approach documented
- NCCI bundling edits checked between same-day cardiac tests before submission
What to confirm before the visit.
- Prior authorization confirmed before scheduling elective interventional procedures (catheterization, stent placement, ablation)
- Authorization verified for advanced imaging (nuclear stress test, cardiac MRI) against the exact CPT code planned
High-dollar interventional claims mean a single denial carries far more weight than in a routine-visit specialty — AR follow-up prioritizes cath lab and device claims ahead of routine visit claims, not on a first-in-first-out basis.
Our workflow for cardiology billing.
Documentation Review
Clinical notes are reviewed to confirm the diagnostic or interventional approach actually documented before coding begins.
Coding & Modifier Check
CPT selection and modifier -25 use are checked against the documented same-day service mix.
Prior Auth Confirmation
For interventional cases, authorization is confirmed before the procedure is scheduled, not after.
High-Value AR Tracking
Cath lab and device claims are followed up ahead of routine visit claims given their dollar value.
What shapes cardiology reimbursement.
Commercial payers and Medicare apply differing frequency limits on repeat diagnostic testing (like stress tests) — documentation needs to support medical necessity for each repeat study, not just the first one.
Cardiology billing, answered.
Do you handle both diagnostic and interventional cardiology billing?
Yes — our cardiology coders work across both diagnostic imaging/testing codes and interventional procedure codes, including the modifier logic that connects them when performed together.
How do you reduce bundling-edit denials on same-day testing?
Claims are scrubbed against current NCCI edit pairs before submission, and we track payer-specific patterns so recurring bundling denials get flagged and corrected at the source, not just appealed after the fact.
