What the Record Tells You
Health Diagnostics of California LLC is an NPI registry record for a radiology clinic/centre at 50 Francisco St, Suite 105 in San Francisco, California 94133. CMS issued NPI 1659302503 on 6 July 2006, and the organisation last updated its own entry on 16 December 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: 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. The same business holds a sibling registration at this address under the name Progressive Radiology Services (NPI 1063680379); they are covered by this page rather than given their own.
San Francisco sits in the San Francisco-Oakland-Fremont, CA metropolitan area (San Francisco 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 Golden Gate Radiology Medical Group, INC. (0.7 miles, San Francisco), Liberty Pacific Medical Imaging of San Francisco, LLC (0.9 miles, San Francisco) and Progressive Radiology Services (0.9 miles, San Francisco), with 1 more within 0.9 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 (415) 433-3535 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.
Full list: cheap MRI, good MRI checklist.
