What the Record Tells You

On Scene Medical Services, P.C. is an NPI registry record for a radiology clinic/centre at 7511 W Arrowhead Ave Ste G in Kennewick, Washington 99336. CMS issued NPI 1578932497 on 21 September 2015, and the organisation last updated its own entry on 28 May 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: 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. It also holds 5 other taxonomy codes (261QE0002X, 261QP2300X, 261QU0200X, 261QX0100X, 291U00000X).

Kennewick sits in the Kennewick-Richland, WA metropolitan area (Benton County), which has 12 imaging-centre records on the Washington side in the September 2026 file, 0 of them with the MRI code, out of 196 across Washington. The nearest alternatives in the registry are Tri City Radiology INC Ps (1.2 miles, Kennewick), Mid-Columbia Ultrasound LLC (2.3 miles, Kennewick) and Kennewick Radiology Group PC (4.0 miles, Kennewick), with 2 more within 4.5 miles.

For a cash-pay benchmark, our Washington freestanding-centre estimate is $700 to $1,900 for a typical single-region MRI. At Washington hospitals the cash price is measured rather than estimated: $539 to $3,078 for a brain MRI, median $1,362, from 32 of the 35 Washington hospitals whose own price files we have read, out of 46 in the state, files dated to August 2026. This centre's own prices are not in the registry: call (509) 420-5225 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 Washington: 32 hospitals measured

Freestanding imaging centre, estimated

$700 to $1,900

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

Hospital outpatient, measured

$539 to $3,078

Median $1,362 cash against a median gross charge of $2,730, from 32 of the 35 Washington hospitals whose own price files we have read, out of 46 in the state, files dated to August 2026.

Seattle market competitive but academic centres (UW, Virginia Mason) at the top. 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 1 hospital publishes a “cash price” that is its chargemaster restated rather than a discount, reaching $2,720; those are kept out of the band above and counted here instead. 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.
