What the Record Tells You

Castro Valley Open MRI Medical Group INC is an NPI registry record for an MRI centre at 21030 Redwood Rd, Suite B in Castro Valley, California 94546. CMS issued NPI 1942592837 on 10 May 2011, and the organisation last updated its own entry on 2 September 2011. 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.

Castro Valley sits in the San Francisco-Oakland-Fremont, CA metropolitan area (Alameda County), which has 129 imaging-centre records on the California side in the August 2026 file, 11 of them with the MRI code, out of 1,312 across California. The nearest alternatives in the registry are Vertebral Motion Diagnostics LLC (0.0 miles, Castro Valley), Bay Imaging Consultants Medical Group INC (0.8 miles, Castro Valley) and Bay Imaging Consultants Medical Group INC (0.8 miles, Castro Valley), with 2 more within 4.3 miles.

For a cash-pay benchmark, our California range is $600 to $1,800 at freestanding imaging centres and $2,200 to $7,500 at hospitals for a typical single-region MRI. This centre's own prices are not in the registry: call (510) 856-4800 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.

What to ask when you call

  1. 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.
  2. Scanner field strength (1.5T or 3T) and whether it is closed, wide-bore or open.
  3. ACR or IAC accreditation, and who reads the images. The registry cannot tell you either.
  4. Whether they accept an order from a telehealth referral if you have no local doctor.

Full list: cheap MRI, good MRI checklist.
