CPT 75741Radiology

Artery x-rays lung

CPT code 75741 covers X-ray imaging of the arteries in the lungs (pulmonary angiography), where contrast dye is injected to visualize blood vessels and diagnose blockages, blood clots, or abnormalities. This diagnostic procedure helps doctors identify conditions like pulmonary embolism or vascular malformations.

Billing tips

Always bill the catheterization code (36014 for selective pulmonary artery catheterization) separately as 75741 covers only the imaging supervision and interpretation
Impact: Bundling error costs approximately $150-200 in lost catheterization procedure reimbursement
Document contrast volume, type, and route of administration in the operative report as payers audit for appropriate contrast use justifying angiography versus other imaging modalities
Impact: Missing contrast documentation accounts for 30% of denials, resulting in $125.18 loss per claim
Use modifier 26 for hospital-based physicians who interpret studies but don't own equipment, ensuring proper component billing split
Impact: Incorrect component billing results in overpayment recoupment or underpayment of approximately $50-75 per study
Link diagnosis codes for pulmonary embolism (I26.x), pulmonary hypertension (I27.x), or other specific vascular conditions rather than screening codes to establish medical necessity
Impact: Non-specific diagnosis codes increase denial rate by 40%, requiring appeals that delay payment by 45-60 days
When performed with interventional procedures on the same day, append modifier 59 to 75741 if distinct diagnostic angiography was performed before deciding on intervention
Impact: Prevents bundling denials that would eliminate the $125.18 diagnostic imaging reimbursement
Submit claims within 30 days of service and include the date of catheterization procedure on the claim form to facilitate matching with facility technical claims
Timely filing and coordinated billing reduces coordination of benefits denials by 25% and accelerates payment by 15-20 days

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 75741 in 2025?

The 2025 Medicare national average reimbursement rate for CPT code 75741 is $125.18 for both facility and non-facility settings. This rate is based on a total RVU of 3.87 multiplied by the 2025 conversion factor of 32.3465.

Can CPT 75741 be billed with cardiac catheterization codes on the same day?

Yes, but requires modifier 59 to indicate a distinct procedural service when pulmonary angiography is performed separately from coronary or cardiac chamber angiography. Documentation must clearly show the pulmonary angiography was a separate diagnostic study with distinct clinical purpose, not bundled within comprehensive cardiac catheterization imaging.

What is the difference between CPT 75741 and 75743?

CPT 75741 covers standard pulmonary angiography supervision and interpretation, while 75743 specifically describes pulmonary angiography performed by venous injection (less selective, typically for pediatric or congenital heart disease evaluation). Code 75741 typically involves selective catheterization directly into the pulmonary arteries for more detailed diagnostic imaging.

Do I need to bill a separate code for the catheterization with 75741?

Yes, CPT 75741 covers only radiological supervision and interpretation. You must separately bill the catheterization procedure code (typically 36014 for selective catheterization of pulmonary artery or 36013 for introduction into pulmonary artery) to capture the complete service and proper reimbursement.

When should I use modifier 26 with CPT code 75741?

Use modifier 26 when billing only the professional component (interpretation and report) without providing the technical component (equipment, staff, supplies). This is common for hospital-employed or contracted radiologists who interpret studies but don't own the equipment. The modifier reduces reimbursement to approximately 40% of the global fee.

What diagnosis codes support medical necessity for CPT 75741?

Primary supporting diagnoses include pulmonary embolism (I26.x series), pulmonary hypertension (I27.x), pulmonary arteriovenous malformation (I28.0), congenital pulmonary artery anomalies (Q25.x), and suspected vascular abnormalities where CT angiography is contraindicated or non-diagnostic. Documentation must explain why catheter angiography is medically necessary over less invasive imaging.

How many RVUs is CPT code 75741 worth in 2025?

CPT code 75741 has a total RVU value of 3.87 in 2025, consisting of 1.31 work RVUs, 2.46 practice expense RVUs, and 0.10 malpractice RVUs. These RVU values are the same for both facility and non-facility settings for this procedure code.
