US Imaging Centers: 12,260 MRI and Radiology Centres by State and Metro

Imaging Centres by State

Records per state in the August 2026 file. "MRI code" counts organisations that registered the MRI clinic/center taxonomy; "metros" counts the Census metro and micropolitan areas with at least two records (each has its own page). Centres outside those areas are listed on the state page.

How to Use the NPI Registry to Find Cash-Pay Centres

The National Provider Identifier registry is the one public list that every imaging business in the US is on, because you cannot bill Medicare or most insurers without an NPI. Here is how to read it for cash-pay shopping.

1. Start from the taxonomy code, not the name

   Organisations registered as 261QM1200X (MRI clinic/center) told CMS they operate MRI; 261QR0200X (radiology clinic/center) covers broader outpatient imaging. Chains such as SimonMed and Envision often register under the physician code 2085R0202X instead, which is why this directory also carries name-classified records, flagged as such.

2. Prefer freestanding organisations over hospital subparts

   NPPES marks records that are subparts of a larger organisation. Hospital-owned outpatient imaging usually bills hospital rates even in a strip-mall building; we exclude hospital subparts unless the record itself is the imaging entity, and we say so on the page.

3. Read the last-update date before you trust the phone number

   53% of these records were last touched before 2020. A recent update is a good sign the phone and address are live; an old one means confirm online or with your referring office first.

4. Call with the CPT code and say the words self-pay

   Ask for the cash price for your exact code (70551 brain, 72148 lumbar spine, 73221 or 73721 joint MRI without contrast), whether the radiologist read is included, and whether the machine is 1.5T or 3T. Compare against the state range and any parsed hospital prices on the metro page.

5. Check the two things the registry cannot tell you

   Accreditation (ACR or IAC) and licensing are not in NPPES. Ask the centre directly, and use our quality checklist before booking on price alone.

Quality questions to ask: cheap MRI, good MRI checklist. Paying without insurance: cash-pay guide.

NPPES is an identifier registry, not a licence register: an NPI does not validate licensure, accreditation or that a scanner is on site. Names, addresses and phones are as self-reported to CMS and many records have not been updated for years; confirm before you travel. Coordinates: US Census Bureau geocoder, ZIP-code centroid where the address did not match (flagged). Metro areas: 2023 Census core-based statistical areas by county. Price ranges: our methodology; hospital cash prices: each hospital's federal transparency file (45 CFR 180), where parsed. No centre pays to be listed and none is endorsed.
