Billing tips

Clearly document the drip infusion technique with specific infusion rate and total volume to differentiate from standard urography (74400)
Impact: Prevents downcoding to 74400 which may reimburse differently; ensures full $144.91 payment
Verify that the medical record specifies the clinical indication requiring drip technique over standard bolus injection
Impact: Medical necessity documentation prevents denials; lack of justification results in 100% claim rejection
Bill 74415 only when the complete drip infusion protocol is performed; incomplete studies require modifier 52 or 53
Impact: Prevents overpayment recoupment in audits which can trigger 20-50% payment reduction plus interest
Do not separately bill for contrast material administration (96365-96368) as it is included in the procedure
Impact: Unbundling results in denial of IV codes and potential overpayment recovery of $50-150 per claim
Ensure timing of images is documented in the report to support the drip infusion methodology
Impact: Absence of timing documentation in audits can trigger recoupment of the 4.48 RVUs worth $144.91
When performed in facility setting, verify facility bills appropriately and professional component uses modifier 26
Impact: Duplicate billing without proper modifiers results in overpayment and potential fraud investigation

Frequently asked questions

What is the Medicare reimbursement rate for CPT 74415 in 2025?

The 2025 Medicare national average reimbursement for CPT 74415 is $144.91 for both facility and non-facility settings. This is based on 4.48 total RVUs (0.49 work RVU, 3.94 PE RVU, 0.05 MP RVU) multiplied by the 2025 conversion factor of 32.3465.

What is the difference between CPT 74415 and 74400?

CPT 74415 is drip infusion urography where contrast is slowly infused intravenously over 10-15 minutes, while 74400 is standard urography with rapid bolus injection. The drip technique (74415) provides better opacification of the urinary collecting system and is used when standard techniques are inadequate or when slower contrast administration is medically indicated.

Can CPT 74415 be billed with a CT urography on the same day?

Yes, but it requires careful documentation of medical necessity for both procedures and typically requires modifier 59 on 74415 to indicate a distinct procedural service. You must document why both imaging modalities were clinically necessary rather than duplicative, such as CT for anatomic detail and drip urography for functional assessment.

What modifiers are commonly used with CPT code 74415?

Common modifiers include 26 (professional component only), TC (technical component only), 59 (distinct procedural service), 76 (repeat procedure by same physician), 52 (reduced services), and 53 (discontinued procedure). Modifier selection depends on whether you're billing for interpretation only, technical services only, or addressing specific billing circumstances.

What documentation is required to bill CPT 74415?

Required documentation includes a physician order with clinical indication, detailed documentation of the drip infusion technique (contrast type, volume, infusion rate), timing of serial images, medical necessity for drip method over standard urography, and a complete signed radiologist interpretation report describing findings in the kidneys, ureters, and bladder.

Who can perform and bill for CPT 74415?

CPT 74415 must be performed under the supervision of and interpreted by a board-certified or board-eligible radiologist. Radiologists, urologists with appropriate privileges, and hospital radiology departments commonly bill this code. The technical portion is performed by radiologic technologists under physician supervision.

Why would a drip infusion urography be ordered instead of standard urography?

Drip infusion urography is ordered when enhanced visualization is needed beyond standard urography, such as in cases of suspected urinary obstruction, hydronephrosis, poor renal function requiring slower contrast administration, or when previous standard urography yielded inadequate images. The slower infusion allows better opacification of the collecting system.
