What the Record Tells You

Mammo Q Plus INC is an NPI registry record for a radiology clinic/centre at 22020 Avalon Blvd in Carson, California 90745. CMS issued NPI 1619044534 on 29 November 2006, and the organisation last updated its own entry on 22 August 2020. That was 6 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.

Carson sits in the Los Angeles-Long Beach-Anaheim, CA metropolitan area (Los Angeles 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 United Urgent Care and Wellness Center, INC. (1.3 miles, Carson), Shahram Bonyadlou, MD, INC. (1.3 miles, Carson) and Harbor/Ucla Diagnostic Imaging Center (2.0 miles, Torrance), with 2 more within 4.3 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 (310) 518-2620 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 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.
