Cardiology billing and testing benefits
Cardiology billing involves diagnostic tests that can count toward the deductible differently from office visits. Before a planned test, we verify benefits, check whether the plan requires a specific site of service, and estimate the patient's share. Patients with pacemakers or defibrillators often have remote monitoring billed on a recurring schedule, so coverage must be active in each billing period.
Authorization for cardiac imaging and procedures
Nuclear stress tests, cardiac CT and MRI, and some echocardiograms often require approval through a radiology benefit manager. Approvals are tied to the code, so a changed study needs an updated request. They also expire after a set window, and a cardiologist reading a study performed elsewhere still needs the authorization number on the professional claim.
Our prior authorization team confirms that the approved code and site match the ordered study and flags any mismatch before the patient arrives.
Coding ECG, echo and stress tests
| Code | Descriptor (summary) |
|---|---|
| 93000 | Electrocardiogram, at least 12 leads, with interpretation and report |
| 93010 | Electrocardiogram interpretation and report only |
| 93306 | Transthoracic echocardiography, complete, with spectral and color flow Doppler |
| 93015 | Cardiovascular stress test, global |
| 93016 / 93017 / 93018 | Stress test supervision only / tracing only / interpretation and report only |
When the practice does not own the equipment, the interpreting cardiologist bills the professional component, using modifier 26 or an interpretation-only code, and the equipment owner bills the technical part. A stress test performed entirely in the office is billed globally. Our coding reviewers check component splits against the place of service on every test claim.
Cardiology claims and denials
Repeat echocardiograms face frequency limits and need a documented change in symptoms, findings or treatment. Interpretations billed without a signed report are another common denial source. Place-of-service errors, such as a global test billed for a study done at an outside site, can lead to recoupments, so they are corrected at charge entry rather than after payment. Recurring denial patterns go to denial management for appeal and a fix upstream.
AR follow-up for cardiology
Our cardiology billing services track professional and technical component payments separately, so a paid read does not hide an unpaid technical claim. Short payments on procedures are reviewed against contract rates, and aged balances are worked by payer through AR management. A free billing assessment shows where your current claims stall.
What makes cardiology billing and coding complex
Cardiology billing and coding spans the office visit, the cath lab, and the imaging suite — and each setting codes differently. Diagnostic catheterizations, interventions, stress testing, and device checks each carry their own bundling rules, global periods, and medical-necessity documentation standards, which is where cardiology medical billing most often loses revenue: not on the big procedures, but on the components that get bundled away or denied for thin documentation. A cardiology billing company that works the full service line keeps global periods, modifiers, and documentation aligned across all three settings, so the claim matches the work every time.
