Missouri Medicare physician rate (2026)
-6.4% vs nationalAverage of 3 localities. Office range $182.63–$196.87.
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.
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 Missouri the office and hospital physician lines for this CPT differ by $130.01.

MRI Knee and how Missouri is priced
Missouri is a three-locality state: metropolitan St. Louis and metropolitan Kansas City are each priced separately, and everywhere else falls into a rest-of-state locality with lower geographic adjustments. Both metro localities approve higher amounts than outstate Missouri, and the Kansas City locality applies only to the Missouri side of that metro, since the Kansas side prices under Kansas's statewide locality. Springfield, Columbia, and the rural counties all share rest-of-state factors. The metro-versus-outstate gap is the main pricing story here.
St. Louis and Kansas City hold the state's academic medical centers and most of its specialty depth, drawing patients from far beyond Missouri's borders, including southern Illinois and eastern Kansas. Outstate Missouri is served by regional hubs in Springfield, Columbia, and Cape Girardeau, with the Ozarks and Bootheel among the harder places to reach specialty care. Rural hospital viability has been a persistent concern across the state.
This procedure: A knee MRI without contrast (the lower extremity joint MRI code) shows the menisci, ligaments including the ACL, cartilage, and bone marrow, none of which appear on X-ray. It is the definitive test for suspected meniscus tears and ligament injuries. You lie on your back with the knee in a small coil for 20 to 40 minutes of painless but noisy scanning, and results typically reach your doctor within a couple of days.

What Affects the Cost
- –The hospital versus freestanding center price gap for knee MRI is large and well documented; this is a scan worth shopping.
- –Insurer authorization rules often require an X-ray and a trial of conservative care first, adding upstream visits.
- –A confirmed meniscus or ligament tear frequently leads to arthroscopy, so the MRI often begins a bigger spending episode.
- –In patients over about 50, MRI often shows incidental degenerative findings that can prompt further, sometimes unnecessary, care.
- –The radiologist's interpretation fee is a distinct component of the price.
Questions to Ask Before Booking
- 1.Has my insurer approved this scan, and does my chart show the X-ray and conservative care they require?
- 2.What is the all-in price at the freestanding centers near me?
- 3.Given my age, could therapy first make this MRI unnecessary?
- 4.Is the authorization tied to a specific facility?
- 5.If the MRI shows a tear, what are the typical next steps and their costs?

After the Part B deductible, coinsurance is usually 20% of the allowed amount: about $38 for the office physician line or $12 for the hospital physician line in Missouri. 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, $191.42 is Medicare's full rate in Missouri, covering the test and the reading. In a hospital outpatient department the physician is paid only for the reading (about $61.41) and the hospital is paid separately, which brings the national total to up to about $307. Missouri ranks #15 of 51 states on the non-hospital rate (6% below the national office rate of $204.41).
