What the Record Tells You

1ST Diagnostics LLC is an NPI registry record for an MRI centre at 5908 Preston Hwy in Louisville, Kentucky 40219. CMS issued NPI 1558129312 on 7 March 2024, and the organisation last updated its own entry on 8 April 2024. That was 2 years ago; the details are probably still current, but confirm the address when you book.

The record carries one imaging taxonomy code: Magnetic Resonance Imaging (MRI) clinic/center (261QM1200X). The MRI-specific code means the organisation registered itself as a magnetic resonance imaging centre, the strongest signal the registry gives that a scanner is on site.

Louisville sits in the Louisville/Jefferson County, KY-IN metropolitan area (Jefferson County), which has 45 imaging-centre records on the Kentucky side in the September 2026 file, 8 of them with the MRI code, out of 181 across Kentucky. The nearest alternatives in the registry are Premier Imaging Solutions LLC (0.9 miles, Louisville), Kentucky/Indiana Foot and Ankle Specialist (2.1 miles, Louisville) and Dxp Imaging (2.5 miles, Louisville), with 2 more within 4.6 miles.

For a cash-pay benchmark, our Kentucky freestanding-centre estimate is $470 to $1,200 for a typical single-region MRI. At Kentucky hospitals the cash price is measured rather than estimated: $615 to $4,136 for a brain MRI, median $2,592, from 34 of the 39 Kentucky hospitals whose own price files we have read, out of 59 in the state, files dated to September 2026. This centre's own prices are not in the registry: call (502) 381-1584 with the CPT code for your scan and ask for the self-pay rate, whether the radiologist's report is included, and the scanner's field strength.

Cash-Price Benchmark

Cash price for a brain MRI in Kentucky: 34 hospitals measured

Freestanding imaging centre, estimated

$470 to $1,200

Our own estimate. No imaging operator publishes a per-state cash price.

Hospital outpatient, measured

$615 to $4,136

Median $2,592 cash against a median gross charge of $4,344, from 34 of the 39 Kentucky hospitals whose own price files we have read, out of 59 in the state, files dated to September 2026.

Louisville and Lexington dominate; rural Eastern KY more expensive. The hospital figures are CPT 70551, brain MRI without contrast, taken from each hospital's own federal transparency file and attributed to the date that file carries. A further 3 hospitals publish a “cash price” that is its chargemaster restated rather than a discount, reaching $5,342; those are kept out of the band above and counted here instead. 1 more hospital lists this code at prices more than three times apart in the same file, from $1,580 to $1,580, so which row is the scan cannot be told from the file; they are excluded from the band and counted here. Hospitals whose file we could not read are named, not filled in (methodology).

What to ask when you call

The self-pay price for your exact CPT code (70551 brain, 72148 lumbar spine, 73221 or 73721 joint, without contrast), and whether the radiologist's report is included.
Scanner field strength (1.5T or 3T) and whether it is closed, wide-bore or open.
ACR or IAC accreditation, and who reads the images. The registry cannot tell you either.
Whether they accept an order from a telehealth referral if you have no local doctor.
