Cardiology Billing That Captures Every Dollar You've Earned

Cardiology revenue hinges on getting the professional/technical split right. Diagnostic echocardiography (CPT 93306, 93307, 93308) and transesophageal echo (93312–93318) are routinely split with modifier 26 for the professional read and TC for the technical component when the cardiologist interprets a study performed on hospital equipment — bill the global code in that setting and the claim is downcoded or denied. Nuclear stress testing (78451–78452) paired with the stress codes 93015–93018 must carry correct supervision and interpretation documentation, and the radiopharmaceutical is billed separately.

The catheterization lab is where most cardiology dollars leak. Diagnostic cath codes (93451–93461) and interventional PCI codes (92920–92944) follow strict bundling and multiple-procedure reduction rules; add-on services like FFR (93571) and IVUS (92978) are frequently dropped or sequenced incorrectly, costing 20–40% of the allowable. Device procedures — pacemaker and ICD insertions (33206–33249) — require precise lead-count and chamber documentation that payers audit aggressively.

Out-of-network exposure is highest for hospital-based and emergency cardiology, where patients can't choose their provider. REL1EF benchmarks interventional and EP claims against Fair Health and UCR data and works them through Zelis/Multiplan negotiation and NSA IDR where appropriate — recovering multiples of the initial payer offer on the same CPT codes. The denial drivers we eliminate at the root: missing modifier 26/TC, medical-necessity edits on echo frequency, and prior-authorization gaps on advanced imaging and devices.
