What the Record Tells You

California Pacific Advanced Imaging is an NPI registry record for an MRI centre at 2351 Clay St Ste 100 in San Francisco, California 94115. CMS issued NPI 1912950676 on 17 May 2006, and the organisation last updated its own entry on 13 June 2024. That was 2 years ago; the details are probably still current, but confirm the address when you book.

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.

San Francisco sits in the San Francisco-Oakland-Fremont, CA metropolitan area (San Francisco County), which has 149 imaging-centre records on the California side in the October 2026 file, 12 of them with the MRI code, out of 1,517 across California. The nearest alternatives in the registry are Fusion Diagnostic Group LLC (0.5 miles, San Francisco), Post Street X-Ray LLC (0.6 miles, San Francisco) and California Advanced Imaging Medical Associates INC (0.7 miles, San Francisco), with 2 more within 0.7 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 (415) 600-3143 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 Medicare Paid This Centre (2024)

From CMS's public Medicare claims data for California Pacific Advanced Imaging (NPI 1912950676). Each row is a scan the centre billed to Medicare for at least 11 patients in 2024.

Scan	Medicare-approved amount	Centre's billed charge	National median approved
Brain MRI without contrast CPT 70551 · 69 Medicare scans	$132	$1,235	$186 (633 centres)
Brain MRI without and with contrast CPT 70553 · 141 Medicare scans	$201	$1,835	$291 (588 centres)
Cervical spine MRI without contrast CPT 72141 · 59 Medicare scans	$125	$1,414	$165 (719 centres)
Lumbar spine MRI without contrast CPT 72148 · 128 Medicare scans	$130	$1,335	$180 (810 centres)
Shoulder or other arm joint MRI without contrast CPT 73221 · 61 Medicare scans	$132	$1,114	$190 (668 centres)
Knee or other leg joint MRI without contrast CPT 73721 · 126 Medicare scans	$129	$1,114	$187 (733 centres)

The Medicare-approved amount is the full amount Medicare accepts for the scan: its own payment plus the patient's share (usually the 20% coinsurance). The billed charge is the centre's own list price on those claims, which Medicare does not pay. Both are averages over the year, and the national column is the median approved amount across every centre that billed Medicare for that scan outside a hospital.

Neither figure is a self-pay quote. If you are paying cash, ask the centre for its self-pay rate for your CPT code and whether the radiologist's report is included.

Source: Centers for Medicare & Medicaid Services, Medicare Physician & Other Practitioners - by Provider and Service, 2024 data, read 15 October 2026. CMS does not publish a centre and scan with fewer than 11 Medicare patients, so a scan missing here may still be offered.

Cash-Price Benchmark

Cash price for a brain MRI in California: 122 hospitals measured

Freestanding imaging centre, estimated

$600 to $1,800

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

Hospital outpatient, measured

$153 to $8,216

Median $2,307 cash against a median gross charge of $5,150, 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.

Bay Area and LA imaging centres are competitive; UCSF and Cedars hospitals at the top end. 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 24 hospitals publish a “cash price” that is its chargemaster restated rather than a discount, reaching $20,680; those are kept out of the band above and counted here instead. 12 more hospitals list this code at prices more than three times apart in the same file, from $19 to $1,825, 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.
