CPT 75565Radiology

Card mri veloc flow mapping

CPT 75565 covers cardiac MRI velocity flow mapping, an advanced imaging technique that measures the speed and direction of blood flow through the heart and major vessels. This add-on test helps doctors evaluate how efficiently blood is moving through the cardiovascular system.

Billing tips

Always bill 75565 as an add-on to a primary cardiac MRI code (75557, 75559, 75561, or 75563); never bill as standalone
Impact: Standalone billing results in 100% denial; proper pairing ensures $43.99 reimbursement
Document the specific anatomic location(s) where velocity flow mapping was performed and clinical indication for quantitative flow assessment
Impact: Detailed documentation reduces medical necessity denials by approximately 60-70% based on payer patterns
Verify that velocity flow mapping sequences are separately documented in the technical protocol and distinct from standard cine imaging
Impact: Clear protocol documentation distinguishes add-on service from base cardiac MRI, supporting the additional $43.99 charge
Report quantitative flow measurements (flow volume in mL/beat, peak velocity in cm/s, regurgitant fraction %) in the interpretation
Impact: Quantitative reporting demonstrates work performed and reduces payment recoupment risk during audits
Review payer-specific policies for cardiac MRI; some commercial payers may require pre-authorization for comprehensive studies including velocity mapping
Impact: Pre-authorization compliance can prevent denial of entire study ($300-800 total depending on base code plus add-ons)
Bill only one unit of 75565 per session regardless of number of locations mapped, per CPT guidelines
Impact: Multiple unit billing triggers automatic denials and potential fraud investigation; single unit=$43.99

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 75565 in 2025?

The 2025 Medicare national average payment for CPT 75565 is $43.99 for both facility and non-facility settings. This rate is based on 1.36 total RVUs multiplied by the 2025 conversion factor of 32.3465.

Can CPT 75565 be billed alone or does it require another code?

CPT 75565 is an add-on code and cannot be billed alone. It must be reported with a primary cardiac MRI code such as 75557, 75559, 75561, or 75563. Billing 75565 as a standalone service will result in denial.

How many times can I bill CPT 75565 in a single MRI session?

CPT 75565 should be reported only once per cardiac MRI session regardless of how many anatomic locations undergo velocity flow mapping. Multiple units of 75565 on the same date of service will typically be denied as duplicates.

What is the work RVU for CPT code 75565?

The 2025 work RVU for CPT 75565 is 0.25, with practice expense RVU of 1.1 and malpractice RVU of 0.01, totaling 1.36 RVUs. This reflects the add-on nature and relatively lower physician work compared to primary cardiac MRI codes.

What documentation is required to support billing CPT 75565?

Documentation must include the specific clinical indication for velocity flow mapping, technical protocol showing phase-contrast sequences, quantitative measurements (velocities, flow volumes, or regurgitant fractions), anatomic locations mapped, and interpretation of hemodynamic significance linked to the primary cardiac MRI findings.

Which medical specialties typically bill CPT code 75565?

CPT 75565 is primarily billed by radiologists and cardiologists with specialized training in cardiac MRI interpretation. This includes cardiovascular radiologists, cardiac imagers, and pediatric cardiologists who perform advanced cardiac MRI studies requiring flow quantification.

What are common reasons for denial of CPT 75565 claims?

Common denials include billing without an appropriate primary cardiac MRI code, lack of medical necessity documentation for velocity flow mapping, incorrect billing of multiple units, and insufficient quantitative reporting in the interpretation to distinguish from standard cine imaging included in the base cardiac MRI.
