What this code covers

Source · Editorial summary grounded in 3 cited references ↓

72156 is the standard cervical MRI contrast protocol: images first without gadolinium, then again after it. It replaces billing 72141 and 72142 together.

Spine surgeons order it for suspected tumor, infection, demyelinating disease that mimics myelopathy, and some postoperative questions. For routine radiculopathy or degenerative myelopathy, non-contrast MRI is usually enough, and payers know that. A reviewer will look for a reason contrast adds information.

Common problems: the order says without contrast, the radiologist adds it, and the authorization never gets updated. Or both 72141 and 72142 go out on the same claim. Gadolinium is billed separately in the office using the HCPCS agent code and correct units. When the cervical, thoracic, and lumbar spine are all imaged, each region gets its own code, and Medicare's multiple procedure reduction cuts payment on the additional studies, mostly on the technical side.

Work RVU vs. total RVU

The work RVU (2.23) is the surgeon's own effort — the figure physician pay and productivity targets are built on. The total RVU (9.52) adds practice overhead and malpractice, and is what drives the Medicare payment below.

Work RVU	2.23
Practice expense RVU	7.13
Malpractice RVU	0.16
Total RVU	9.52
Medicare national rate	$317.98

Payment by site of service

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

Frequently asked questions

Source · Generated from the editorial pipeline, verified against 3 cited references ↓

01Can I bill 72141 and 72142 together?

No. A without-and-with cervical MRI in one session is billed as 72156.

02Is contrast needed for cervical radiculopathy MRI?

Usually not. Payers expect a specific reason such as tumor, infection, or postoperative evaluation.

03How do I bill MRI of the whole spine with and without contrast?

Bill 72156, 72157, and 72158 for the cervical, thoracic, and lumbar regions. Medicare reduces payment on the second and third studies under the imaging multiple procedure rule.
