What this code covers

Source · Editorial summary grounded in 3 cited references ↓

71555 is an MR angiogram of the chest vessels, such as the aorta and its branches, with or without contrast. It does not cover cardiac imaging. The CMS status indicator for this code is R, which means Medicare covers it only in restricted circumstances.

Orthopedic practices rarely touch this code. The most plausible overlap is thoracic outlet syndrome, where a shoulder or upper extremity surgeon is evaluating arm symptoms and the subclavian vessels need imaging. Vascular surgery or radiology usually owns the study.

The restricted status is the main billing issue. Medicare's MRA coverage determination limits chest MRA to specific indications, and anything outside those will deny. Commercial plans tend to require authorization and may prefer CTA. Before ordering, confirm the indication is covered and that the patient can have MRI.

RVU & reimbursement

Component RVUs and Medicare national rate. Actual payment varies by GPCI locality.

Work RVU vs. total RVU

The work RVU (1.76) is the surgeon's own effort — the figure physician pay and productivity targets are built on. The total RVU (10.01) adds practice overhead and malpractice, and is what drives the Medicare payment below.

Payment by site of service

Medicare pays different rates by setting. HOPD typically pays substantially more than ASC for the same procedure.

Common denial reasons

The recurring reasons claims for CPT 71555 get rejected.

Source · Editorial brief grounded in CMS NCCI edits, AAOS coding appeals, and cited references ↓

  • No ABN when billing a Medicare patient for a non-covered indication
  • Authorization not obtained
  • Diagnosis is musculoskeletal pain with no vascular concern
  • Billed for cardiac imaging, which uses other codes

01What does status indicator R mean for 71555?
Medicare covers the code only in restricted circumstances. Check the MRA coverage determination for the allowed indications.
02Is 71555 used for thoracic outlet syndrome?
