What the Record Tells You

Alliance Healthcare Services INC is an NPI registry record for an MRI centre at 4520 E Grant Rd Ste 100 in Tucson, Arizona 85712. CMS issued NPI 1982919411 on 9 August 2010, and the organisation last updated its own entry on 9 February 2012. That was 14 years ago, so treat the phone number and suite as unverified until you have spoken to someone there.

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.

Tucson sits in the Tucson, AZ metropolitan area (Pima County), which has 40 imaging-centre records on the Arizona side in the September 2026 file, 8 of them with the MRI code, out of 360 across Arizona. The nearest alternatives in the registry are Simonmed Imaging (0.8 miles, Tucson), Arizona Community Physicians PC (0.9 miles, Tucson) and Arizona Community Physicians PC (1.0 miles, Tucson), with 2 more within 1.2 miles.

For a cash-pay benchmark, our Arizona freestanding-centre estimate is $500 to $1,400 for a typical single-region MRI. At Arizona hospitals the cash price is measured rather than estimated: $347 to $5,618 for a brain MRI, median $516, from 27 of the 45 Arizona hospitals whose own price files we have read, out of 66 in the state, files dated to August 2026. This centre's own prices are not in the registry: call (520) 289-8089 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 Arizona: 27 hospitals measured

Freestanding imaging centre, estimated

$500 to $1,400

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

Hospital outpatient, measured

$347 to $5,618

Median $516 cash against a median gross charge of $3,014, from 27 of the 45 Arizona hospitals whose own price files we have read, out of 66 in the state, files dated to August 2026.

Phoenix and Tucson markets are competitive with growing freestanding 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 8 hospitals publish a “cash price” that is its chargemaster restated rather than a discount, reaching $3,014; those are kept out of the band above and counted here instead. 3 more hospitals list this code at prices more than three times apart in the same file, from $116 to $446, 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.
