What the Record Tells You

Nydic Open MRI of America-St. Peters, the trading name of Open MRI of Missouri II, L.L.C., is an NPI registry record for an MRI centre and radiology clinic at 5650 Mexico Rd, Suite 10 in Saint Peters, Missouri 63376. CMS issued NPI 1730124918 on 19 June 2006, and the organisation last updated its own entry on 11 September 2025. That is recent, so the contact details are likely current.

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. One other imaging record shares this street address: St Peters MRI & Imaging.

Saint Peters sits in the St. Louis, MO-IL metropolitan area (St. Charles County), which has 84 imaging-centre records on the Missouri side in the September 2026 file, 14 of them with the MRI code, out of 211 across Missouri. The nearest alternatives in the registry are St Peters MRI & Imaging (0.0 miles, Saint Peters), St. Peters MRI & Imaging Center, LLC (0.3 miles, St Peters) and Imaging Partners of St. Peters, LLC (0.9 miles, Saint Peters), with 2 more within 6.2 miles.

For a cash-pay benchmark, our Missouri freestanding-centre estimate is $480 to $1,300 for a typical single-region MRI. At Missouri hospitals the cash price is measured rather than estimated: $237 to $2,884 for a brain MRI, median $1,168, from 28 of the 37 Missouri hospitals whose own price files we have read, out of 62 in the state, files dated to July 2026. This centre's own prices are not in the registry: call (636) 477-7277 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 Missouri: 28 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

$237 to $2,884

Median $1,168 cash against a median gross charge of $2,420, from 28 of the 37 Missouri hospitals whose own price files we have read, out of 62 in the state, files dated to July 2026.

St Louis and Kansas City have competitive independent networks. 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 4 hospitals publish a “cash price” that is its chargemaster restated rather than a discount, reaching $10,840; those are kept out of the band above and counted here instead. 5 more hospitals list this code at prices more than three times apart in the same file, from $278 to $2,709, 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.
