What the Record Tells You

Diagnostic Health Alaska, the trading name of Diagnostic Health Center of Anchorage, LLC, is an NPI registry record for a radiology clinic/centre at 4100 Lake Otis Pkwy, Suite 102 in Anchorage, Alaska 99508. CMS issued NPI 1235188426 on 8 May 2006, and the organisation last updated its own entry on 24 July 2023. That was 3 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.

Anchorage sits in the Anchorage, AK metropolitan area (Anchorage Municipality), which has 18 imaging-centre records on the Alaska side in the October 2026 file, 0 of them with the MRI code, out of 42 across Alaska. The nearest alternatives in the registry are Matrix Radiology Associates, LLC (0.2 miles, Anchorage), Alaska Family Sonograms, INC (0.3 miles, Anchorage) and Imaging Associates (0.4 miles, Anchorage), with 2 more within 0.8 miles.

For a cash-pay benchmark, our Alaska freestanding-centre estimate is $800 to $2,200 for a typical single-region MRI. At Alaska hospitals the cash price is measured rather than estimated: $1,541 to $4,177 for a brain MRI, median $2,998, from 3 of the 7 Alaska hospitals whose own price files we have read, out of 8 in the state, files dated to August 2026. This centre's own prices are not in the registry: call (907) 729-5800 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 Diagnostic Health Alaska (NPI 1235188426). 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
Head CT without contrast CPT 70450 · 27 Medicare scans	$122	$1,041	$98 (401 centres)
Chest X-ray, 2 views CPT 71046 · 31 Medicare scans	$39	$149	$31 (743 centres)
Cervical spine MRI without contrast CPT 72141 · 102 Medicare scans	$205	$2,883	$165 (719 centres)
Lumbar spine MRI without contrast CPT 72148 · 154 Medicare scans	$226	$2,901	$180 (810 centres)
Shoulder or other arm joint MRI without contrast CPT 73221 · 29 Medicare scans	$235	$2,438	$190 (668 centres)
Knee or other leg joint MRI without contrast CPT 73721 · 33 Medicare scans	$230	$2,358	$187 (733 centres)
Abdomen and pelvis CT with contrast CPT 74177 · 13 Medicare scans	$352	$2,617	$286 (419 centres)
Abdominal ultrasound, complete CPT 76700 · 12 Medicare scans	$134	$520	$109 (647 centres)
Screening mammogram, both breasts CPT 77067 · 163 Medicare scans	$145	$415	$118 (320 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 Alaska: 3 hospitals measured

Freestanding imaging centre, estimated

$800 to $2,200

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

Hospital outpatient, measured

$1,541 to $4,177

Median $2,998 cash against a median gross charge of $4,786, from 3 of the 7 Alaska hospitals whose own price files we have read, out of 8 in the state, files dated to August 2026.

Limited competition outside Anchorage drives prices up. 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 3 hospitals publish a “cash price” that is its chargemaster restated rather than a discount, reaching $5,282; 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.

Full list: cheap MRI, good MRI checklist.
