What the whole procedure costs

The office rate above is what an imaging center, lab or office is paid for the whole test. In a hospital, the facility bills its own fee and the physician bills only the reading. These are 2026 national Medicare amounts.

Physician reading alone
$68
Only 22% of the hospital total

Medicare may pay the facility separately for this code or package it into another service on the same day, so treat the facility share as an upper bound. For a test like this the physician in a hospital bills only the reading (the professional component); outside a hospital one global fee covers the whole test, shown in the office rate above. Medicare allowed amounts are not what an uninsured patient is charged, and not a quote. Private plans typically allow more.

What these numbers are

Every figure on this page is a 2026 Medicare allowed amount: the physician line comes from the Physician Fee Schedule adjusted by geographic practice-cost indices, and the facility totals come from the CMS hospital outpatient (OPPS) and ambulatory surgery center rates. None of them is a hospital chargemaster price, your insurer's contracted rate, or a quote. Anesthesia, pathology, imaging reads and follow-up care are billed under their own codes when they apply, and an inpatient stay is paid a different way again. In Idaho the office and hospital physician lines for this CPT differ by $113.09.

MRI Lumbar Spine and how Idaho is priced

All of Idaho shares a single payment locality, and its geographic indices are among the lowest in the West, so Medicare-approved amounts here undercut those in neighboring Washington and Oregon metro localities. Boise's rapid growth has not changed the statewide pricing structure; the fee schedule treats the Treasure Valley the same as the Panhandle or the eastern farm counties. For patients, that uniformity makes the statewide figures on this site a reliable guide anywhere in Idaho. Cross-border care is where pricing gets more interesting, since adjacent metro localities price higher.

Boise anchors the state's largest medical market, while the Panhandle looks to Spokane, Washington for much of its specialty care and eastern Idaho leans on Idaho Falls, Pocatello, and sometimes Salt Lake City. That means many Idahoans actually receive care priced under another state's locality. Rural and mountain communities face long drives for anything beyond primary care.

This procedure: A lumbar spine MRI without contrast images the lower back, the region responsible for most back pain and sciatica, showing discs, nerve roots, and the spinal canal. It is the definitive test before considering injections or surgery for a suspected herniated disc or spinal stenosis. You lie on your back in the scanner for 20 to 40 minutes; it is painless but the flat position can be uncomfortable if lying down aggravates your pain.

What Is MRI Lumbar Spine?

A lumbar spine MRI without contrast images the lower back, the region responsible for most back pain and sciatica, showing discs, nerve roots, and the spinal canal. It is the definitive test before considering injections or surgery for a suspected herniated disc or spinal stenosis. You lie on your back in the scanner for 20 to 40 minutes; it is painless but the flat position can be uncomfortable if lying down aggravates your pain.

What Affects the Cost

  • –This is one of the most shopped scans in America, and prices between hospitals and independent centers commonly differ several-fold.
  • –Insurer rules pushing six weeks of conservative care first mean therapy visit costs often precede the scan.
  • –Findings frequently lead to epidural injections or surgical consultations, so the MRI is often the gateway to a much larger episode of spending.
  • –Contrast is only added for specific concerns like prior surgery or infection, at a higher-code price.
  • –Open or wide-bore scanners for larger or claustrophobic patients can carry different pricing at specialty centers.

Questions to Ask Before Booking

  • 1.Do I meet my insurer's criteria yet, or will this be denied for lack of conservative treatment first?
  • 2.What is the cash or negotiated price at nearby freestanding imaging centers?
  • 3.Is my scan authorized at the specific location I am booked at?
  • 4.Given my history, does the radiologist need contrast, and what would that add?
  • 5.If the MRI shows a disc problem, what are the typical next-step costs I should anticipate?

MRI Lumbar Spine in Idaho: questions

Under 2026 Medicare rates, an MRI lumbar spine costs up to about $312 in total at a hospital outpatient department, counting both the physician and the facility (national rates). Outside a hospital, at an independent imaging center, lab or office, Medicare's full rate in Idaho averages $179. Idaho is a single Medicare locality, so the physician rate is the same statewide.

Not on the physician fee schedule. Idaho uses one locality, so the Medicare physician rate is the same from one end of the state to the other. What still changes is site of service (office vs hospital) and any facility fee the hospital bills on its own claim.

After the Part B deductible, coinsurance is usually 20% of the allowed amount: about $36 for the office physician line or $13 for the hospital physician line in Idaho. Medigap may cover that 20%. This is not the hospital facility fee.

It depends on where the test is done. At an independent imaging center, lab or office, $178.74 is Medicare's full rate in Idaho, covering the test and the reading. In a hospital outpatient department the physician is paid only for the reading (about $65.65) and the hospital is paid separately, which brings the national total to up to about $312. Idaho ranks #10 of 51 states on the non-hospital rate (7% below the national office rate of $191.72).
