Billing tips

Verify all components are documented: right atrial pressure, right ventricular pressure, pulmonary artery pressure, and complete angiographic imaging of coronary arteries or grafts
Impact: Missing any component documentation can result in downcoding to a lower-paying code (93456 at $1019.43 or 93503 at $282.68), reducing revenue by $116.26 to $853.01 per case
Do not separately bill for routine fluoroscopic guidance (77001) or catheter placement codes - these are bundled into 93457
Impact: Prevents automatic denials and recoupment of $50-150 per case; reduces audit risk and claim rework time
When billing with left heart catheterization on same day, use appropriate combination codes (93460-93461) instead of billing 93457 separately
Impact: Using combination code 93460 ($1425.74) or 93461 ($1644.38) prevents unbundling denials and captures appropriate higher reimbursement for combined procedures
Bill facility vs non-facility based on actual place of service; both have same rate ($1135.69) for 93457 but impacts other bundled charges
Impact: Correct POS coding ensures proper coordination of benefits and prevents secondary payer denials
Document medical necessity for performing right heart catheterization with angiography - indication must support both components
Impact: Prevents LCD/NCD denials; approximately 15-20% of cardiac catheterization denials relate to medical necessity of combined procedures
Report number of coronary arteries or bypass grafts imaged in documentation; ensure images are stored and retrievable for audit
Essential for appeals and audits; missing images can result in full recoupment of $1135.69 per case during post-payment review

Frequently asked questions

What is the Medicare reimbursement rate for CPT 93457 in 2025?

The 2025 Medicare national average reimbursement rate for CPT 93457 is $1135.69 for both facility and non-facility settings. This is based on 35.11 total RVUs (6.64 work RVU, 27.17 PE RVU, 1.3 MP RVU) multiplied by the 2025 conversion factor of 32.3465.

Can I bill CPT 93457 with a left heart catheterization on the same day?

No, you should not bill CPT 93457 separately when performing both right and left heart catheterization during the same session. Instead, use combination codes CPT 93460 (with left ventriculography) or 93461 (with pharmacologic stress) which include both right and left heart catheterization components and provide appropriate reimbursement for the combined procedure.

What is the difference between CPT 93457 and 93456?

CPT 93457 includes right heart catheterization with coronary or bypass graft angiography, while CPT 93456 includes right heart catheterization with left heart catheterization but without any angiography. Code 93457 requires documentation of both right-sided pressure measurements and angiographic imaging of coronary arteries or grafts.

What documentation is required to bill CPT 93457?

Required documentation includes medical necessity for both components, venous access site, right atrial and ventricular pressure measurements with numerical values, pulmonary artery pressures, angiographic images of coronary arteries or bypass grafts with specific vessels identified, interpretation of both hemodynamic and angiographic findings, contrast volume, and physician signature on the final report.

How many RVUs is CPT code 93457 worth in 2025?

CPT 93457 is assigned 35.11 total RVUs in 2025, consisting of 6.64 work RVUs, 27.17 practice expense RVUs (both facility and non-facility), and 1.3 malpractice RVUs according to the CMS Medicare Physician Fee Schedule RVU25A released December 23, 2024.

Can CPT 93457 be billed with modifier 26 for professional component only?

Yes, CPT 93457 can be billed with modifier 26 when the physician is only providing the professional component (interpretation and report) while the facility bills the technical component separately with modifier TC. This is common in hospital-based settings where the facility owns the equipment and employs technical staff.

What are common NCCI bundling issues with CPT 93457?

Common NCCI bundling violations include separately billing catheter placement codes, routine fluoroscopic guidance (77001), separate pressure measurement codes (93503), or injection procedure codes that are integral to the catheterization. These services are bundled into 93457 and billing them separately will result in denials. Only distinct, medically necessary additional services with proper modifier 59 documentation should be billed separately.
