Billing tips

Clearly document whether contrast was administered, type of contrast used, dosage, and medical necessity for contrast enhancement in the radiology report
Impact: Prevents denials for lack of medical necessity documentation; contrast-related queries account for 25-30% of MRA audit findings
Verify correct code selection between 73725 (MR angiography) and 73721/73723 (standard MRI lower extremity) as payers frequently deny when angiography technique is not clearly documented
Impact: Code confusion can result in $80-150 payment difference and requires resubmission, delaying payment 45-60 days
When billing globally (both professional and technical components), ensure place of service code matches the actual location and supports full reimbursement of $331.55
Impact: Incorrect POS codes trigger automatic downcoding to facility-only rates or denials requiring appeals
Include specific ICD-10 codes documenting vascular symptoms (claudication, rest pain, non-healing ulcers) rather than screening codes to establish medical necessity
Impact: Screening indications result in 60-70% denial rate; symptom-based coding improves first-pass acceptance to 85-90%
For bilateral lower extremity MRA studies, verify payer policy on billing two units versus modifier 50 versus separate line items with RT/LT modifiers
Impact: Incorrect bilateral billing method causes automatic denials or 50% payment reduction requiring corrected claims
Ensure radiologist interpretation is completed and signed within payer timeframe (typically 24-72 hours) before claim submission to avoid technical-only payment

What is the Medicare reimbursement rate for CPT code 73725 in 2025?

The 2025 Medicare national average reimbursement rate for CPT 73725 is $331.55 for both facility and non-facility settings. This rate is based on the total RVU of 10.25 multiplied by the 2025 conversion factor of 32.3465, as published in the CMS Physician Fee Schedule.

What is the difference between CPT 73725 and 73721?

CPT 73725 is MR angiography of the lower extremity, specifically focused on imaging blood vessels using specialized angiographic sequences with or without contrast. CPT 73721 is a standard MRI of any joint of the lower extremity without contrast, focused on soft tissue, bone, and joint structures rather than vascular anatomy. The angiography code requires vascular-specific imaging protocols.

Does CPT 73725 require contrast dye to be billed?

No, CPT 73725 can be billed with or without contrast dye. The descriptor explicitly states 'with or without contrast material(s).' However, documentation must clearly indicate whether contrast was used and, if used, the medical necessity for contrast administration must be supported in the clinical record.

How many RVUs is CPT code 73725 worth?

CPT 73725 has a total RVU value of 10.25 for 2025, consisting of 1.82 work RVUs, 8.29 practice expense RVUs, and 0.14 malpractice RVUs. Both facility and non-facility PE RVUs are identical at 8.29 for this code.

Can you bill CPT 73725 bilaterally for both legs?

Yes, bilateral lower extremity MR angiography can be billed, but you must follow your specific payer's bilateral procedure policy. Some payers accept modifier 50, others require two line items with RT/LT modifiers, and some require billing two units. Medicare typically allows 150% reimbursement for bilateral procedures when properly documented and coded according to their bilateral surgery rules.

What diagnosis codes support medical necessity for CPT 73725?

Common supporting ICD-10 codes include I70.2xx (atherosclerosis of native arteries of extremities), I80.2xx (phlebitis and thrombophlebitis of lower extremity veins), I87.2 (venous insufficiency), L97.xxx (non-pressure chronic ulcer of lower limb), and I73.9 (peripheral vascular disease, unspecified). Specific payer LCDs should be reviewed for complete coverage criteria.

Who can perform and interpret CPT 73725?

CPT 73725 must be interpreted by a qualified physician, typically a board-certified radiologist or physician with specialized training in MR angiography interpretation. The technical component is performed by certified MRI technologists under appropriate physician supervision. The interpreting physician must provide a written report and signature to bill the professional component or global service.
