What the Record Tells You
Orange County Diagnostics, the trading name of University Diagnotics, INC., is an NPI registry record for a radiology clinic/centre at 27725 Santa Margarita Parkway, Suite 101 in Mission Viejo, California 92691. CMS issued NPI 1306835038 on 15 October 2005, and the organisation last updated its own entry on 14 August 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 2 imaging taxonomy codes: Radiology clinic/center (261QR0200X) and Mammography clinic/center (261QR0206X). It registered as a radiology clinic without the MRI-specific code, so ask which modalities it operates before assuming an MRI is available.
Mission Viejo sits in the Los Angeles-Long Beach-Anaheim, CA metropolitan area (Orange County), which has 658 imaging-centre records on the California side in the September 2026 file, 57 of them with the MRI code, out of 1,513 across California. The nearest alternatives in the registry are Seyed H. Shahrokni, MD, INC. (0.0 miles, Mission Viejo), The Osteoporosis Center of Irvine (0.0 miles, Mission Viejo) and South Coast Radiological Medical Group INC (2.5 miles, Laguna Hills), with 2 more within 2.6 miles.
For a cash-pay benchmark, our California freestanding-centre estimate is $600 to $1,800 for a typical single-region MRI. At California hospitals the cash price is measured rather than estimated: $153 to $8,216 for a brain MRI, median $2,307, from 122 of the 169 California hospitals whose own price files we have read, out of 276 in the state, files dated to September 2026. This centre's own prices are not in the registry: call (949) 462-3999 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
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.
