What the Record Tells You

Advanced Diagnostic Imaging, the trading name of Cedar Valley Medical Specialists PC, is an NPI registry record for a radiology clinic/centre at 4006 Johnathan St in Waterloo, Iowa 50701. CMS issued NPI 1841245586 on 23 May 2006, and the organisation last updated its own entry on 5 February 2026. That is recent, so the contact details are likely current.

The record carries one imaging taxonomy code: Radiology clinic/center (261QR0200X). It registered as a radiology clinic without the MRI-specific code, so ask which modalities it operates before assuming an MRI is available. CMS records it as a subpart of Cedar Valley Medical Specialists, PC, so pricing may follow the parent's policies. One other imaging record shares this street address: Ascent Imaging, LLC.

Waterloo sits in the Waterloo-Cedar Falls, IA metropolitan area (Black Hawk County), which has 2 imaging-centre records on the Iowa side in the September 2026 file, 0 of them with the MRI code, out of 74 across Iowa. The nearest alternatives in the registry are Ascent Imaging, LLC (0.0 miles, Waterloo), Open MRI of Chicago (24 miles, Chicago) and Waves Advanced Ultrasound (44 miles, Hiawatha), with 2 more within 49 miles.

For a cash-pay benchmark, our Iowa freestanding-centre estimate is $480 to $1,250 for a typical single-region MRI. At Iowa hospitals the cash price is measured rather than estimated: $900 to $4,896 for a brain MRI, median $2,034, from 20 of the 22 Iowa hospitals whose own price files we have read, out of 30 in the state, files dated to September 2026. This centre's own prices are not in the registry: call (319) 236-2700 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 Iowa: 20 hospitals measured

Freestanding imaging centre, estimated

$480 to $1,250

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

Hospital outpatient, measured

$900 to $4,896

Median $2,034 cash against a median gross charge of $2,851, from 20 of the 22 Iowa hospitals whose own price files we have read, out of 30 in the state, files dated to September 2026.

Des Moines and Iowa City have the most providers. 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 $229; those are kept out of the band above and counted here instead. 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.
