What this code covers
Source · Editorial summary grounded in 3 cited references ↓
73725 is MR angiography of the leg. Ortho uses include vascular evaluation after a knee dislocation in a patient who cannot get iodinated contrast, popliteal artery entrapment in athletes, vascular malformations, and planning for free tissue transfer or limb salvage.
The status indicator is R, so Medicare coverage is restricted. The Medicare NCD for magnetic resonance angiography lists the covered indications. Read it against the patient's diagnosis before scheduling. A purely musculoskeletal reason is unlikely to fit. When the reason falls outside the NCD, get a signed ABN before the scan and append GA. Without it, the claim is denied and the patient cannot be billed.
The code covers the study with or without contrast, so do not split it. A same-day MRI of the leg for bone or soft tissue is a different study and needs its own order and report. Commercial plans generally require prior authorization, and some will steer the order to CTA or duplex ultrasound first.
RVU & reimbursement
Component RVUs and Medicare national rate. Actual payment varies by GPCI locality.

Work RVU vs. total RVU
The work RVU (1.77) is the surgeon's own effort — the figure physician pay and productivity targets are built on. The total RVU (10.09) adds practice overhead and malpractice, and is what drives the Medicare payment below.
| Work RVU | 1.77 |
| Practice expense RVU | 8.17 |
| Malpractice RVU | 0.15 |
| Total RVU | 10.09 |
| Medicare national rate | $337.02 |
| Global period | days |
Payment by site of service
Medicare pays different rates by setting. HOPD typically pays substantially more than ASC for the same procedure.
