What the Record Tells You

Ascension Medical Group St. Vincent, the trading name of St. Vincent Medical Group, INC., is an NPI registry record for an MRI centre and radiology clinic at 2155 E Main St, 150 in Plainfield, Indiana 46168. CMS issued NPI 1902349483 on 1 December 2016, and the organisation last updated its own entry on 12 February 2020. That was 6 years ago, so treat the phone number and suite as unverified until you have spoken to someone there.

The record carries 2 imaging taxonomy codes: Magnetic Resonance Imaging (MRI) clinic/center (261QM1200X) and Radiology clinic/center (261QR0200X). 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. It also holds one other taxonomy code (293D00000X).

Plainfield sits in the Indianapolis-Carmel-Greenwood, IN metropolitan area (Hendricks County), which has 52 imaging-centre records on the Indiana side in the September 2026 file, 5 of them with the MRI code, out of 191 across Indiana. The nearest alternatives in the registry are Proscan Imaging of Avon (5.2 miles, Avon), Diagnostic Health Serives (5.3 miles, Mooresville) and Hendricks County Radiology INC (7.9 miles, Danville), with 2 more within 13 miles.

For a cash-pay benchmark, our Indiana freestanding-centre estimate is $480 to $1,300 for a typical single-region MRI. At Indiana hospitals the cash price is measured rather than estimated: $137 to $3,765 for a brain MRI, median $693, from 24 of the 31 Indiana hospitals whose own price files we have read, out of 82 in the state, files dated to September 2026. This centre's own prices are not in the registry: call (317) 204-6850 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 Indiana: 24 hospitals measured

Freestanding imaging centre, estimated

$480 to $1,300

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

Hospital outpatient, measured

$137 to $3,765

Median $693 cash against a median gross charge of $2,032, from 24 of the 31 Indiana hospitals whose own price files we have read, out of 82 in the state, files dated to September 2026.

Indianapolis dominates; IU Health and Community Health are large systems. 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 1 hospital publishes a “cash price” that is its chargemaster restated rather than a discount, reaching $3,750; those are kept out of the band above and counted here instead. 2 more hospitals list this code at prices more than three times apart in the same file, from $496 to $2,688, 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.

Full list: cheap MRI, good MRI checklist.
