CPT 75902Radiology

Remove cva lumen obstruct

CPT code 75902 covers the radiological supervision and interpretation for removing a blockage from a central venous access device (like a port or PICC line). This is an imaging-only code that documents the physician's work in guiding and interpreting the clearance procedure using fluoroscopy or other imaging.

Billing tips

Always bill 75902 separately from the mechanical declotting code 36595 - these are not bundled and represent distinct components (imaging vs. procedure)
Impact: Captures additional $82.81 that is commonly missed when only the mechanical clearance code is billed
Document the number of fluoroscopic images, total fluoroscopy time, and specific findings (clot location, catheter tip position, contrast flow patterns) to support medical necessity
Impact: Reduces audit risk and denial rate by 30-40% compared to minimal documentation
Verify whether your facility or the physician owns the imaging equipment to determine correct modifier usage (26/TC vs. global)
Impact: Incorrect modifier usage results in 100% denial or significant underpayment; proper split billing can optimize revenue for both entities
When performing multiple CVAD procedures on the same day, append modifier 59 to 75902 if the imaging is for a separate and distinct declotting procedure
Impact: Prevents automatic NCCI bundling denials that would otherwise reduce payment to $0
Bill only once per catheter per session regardless of the number of lumens cleared - 75902 is per catheter, not per lumen
Impact: Billing multiple units for multi-lumen catheters triggers 100% denial of additional units and potential fraud review
Ensure the interpreting physician creates a separate, signed radiological report documenting the supervision and interpretation work
Impact: Absence of formal interpretation report is the #1 reason for post-payment recoupment during audits

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 75902 in 2025?

The 2025 Medicare national average payment for CPT 75902 is $82.81 for both facility and non-facility settings. This is based on 2.56 total RVUs multiplied by the 2025 conversion factor of 32.3465. Actual payment may vary by geographic locality.

Can CPT 75902 be billed with code 36595 on the same day?

Yes, CPT 75902 (radiological supervision and interpretation) should be billed separately from CPT 36595 (mechanical clearance of CVAD obstruction) when both services are performed. These codes are not bundled under NCCI edits. The radiologist bills 75902 for imaging interpretation while the proceduralist bills 36595 for the actual clearance procedure.

How many times can I bill CPT 75902 for a multi-lumen catheter?

CPT 75902 should be billed only once per catheter per session, regardless of the number of lumens cleared. The code represents the radiological supervision for the entire catheter clearance procedure, not per individual lumen. Billing multiple units for a multi-lumen catheter will result in denials.

What documentation is required to bill CPT 75902?

A separate, formal radiological interpretation report is required, documenting the fluoroscopic or radiographic guidance provided, catheter position, obstruction findings, images obtained, fluoroscopy time, and post-procedure patency assessment. This must be distinct from the procedural note for the mechanical clearance and signed by the interpreting physician.

Do I need modifier 26 or TC when billing CPT 75902?

Use modifier 26 (professional component) when billing only for the physician's interpretation and the facility owns the equipment. Use modifier TC (technical component) when billing only for the equipment and technologist. If the same entity provides both components, bill the global code without modifiers. Split billing is common in hospital settings.

What is the work RVU for CPT code 75902?

The 2025 work RVU for CPT 75902 is 0.39, with practice expense RVUs of 2.13 (both facility and non-facility) and malpractice RVU of 0.04, totaling 2.56 total RVUs. The work RVU represents the physician's cognitive and technical effort in performing the radiological supervision and interpretation.

What are common denial reasons for CPT 75902 and how can I prevent them?

Common denials include missing radiological interpretation reports, incorrect bundling assumptions with 36595, and billing multiple units for multi-lumen catheters. Prevent denials by ensuring a separate signed radiology report exists, understanding that 75902 and 36595 are separately billable, and billing only one unit per catheter regardless of lumens cleared.
