What the Record Tells You
Ara/St. David's Imaging, LP is an NPI registry record for a radiology clinic/centre at 2120 N Mays St, Suite 220 in Round Rock, Texas 78664. CMS issued NPI 1720065170 on 28 December 2005, and the organisation last updated its own entry on 10 July 2024. That was 2 years ago; the details are probably still current, but confirm the address when you book.
The record carries 2 imaging taxonomy codes: Radiology clinic/center (261QR0200X) and Mobile radiology clinic/center (261QR0208X). It registered as a radiology clinic without the MRI-specific code, so ask which modalities it operates before assuming an MRI is available.
Round Rock sits in the Austin-Round Rock-San Marcos, TX metropolitan area (Williamson County), which has 84 imaging-centre records on the Texas side in the October 2026 file, 7 of them with the MRI code, out of 1,458 across Texas. The nearest alternatives in the registry are Akumin (1.8 miles, Round Rock), Family Imaging Services (1.8 miles, Round Rock) and Patient First Imaging, LLC (1.8 miles, Round Rock), with 2 more within 6.0 miles.
For a cash-pay benchmark, our Texas freestanding-centre estimate is $500 to $1,400 for a typical single-region MRI. At Texas hospitals the cash price is measured rather than estimated: $236 to $10,390 for a brain MRI, median $2,190, from 125 of the 194 Texas hospitals whose own price files we have read, out of 285 in the state, files dated to September 2026. Published hospital cash prices in Austin-Round Rock-San Marcos run from $2,260.29 (Baylor Scott & White Medical Center - Marble Falls) to $2,556.77 (Baylor Scott & White Medical Center - Lakeway) for a brain MRI without contrast, from the hospitals' federal transparency files. This centre's own prices are not in the registry: call (512) 238-7195 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 Ara/St. David's Imaging, LP (NPI 1720065170). 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 · 162 Medicare scans | $53 | $287 | $98 (401 centres) |
| Brain MRI without contrast CPT 70551 · 147 Medicare scans | $106 | $703 | $186 (633 centres) |
| Brain MRI without and with contrast CPT 70553 · 389 Medicare scans | $167 | $1,043 | $291 (588 centres) |
| Chest X-ray, 2 views CPT 71046 · 536 Medicare scans | $17 | $62 | $31 (743 centres) |
| Chest CT without contrast CPT 71250 · 404 Medicare scans | $74 | $280 | $124 (492 centres) |
| Cervical spine MRI without contrast CPT 72141 · 289 Medicare scans | $93 | $703 | $165 (719 centres) |
| Lumbar spine MRI without contrast CPT 72148 · 590 Medicare scans | $105 | $709 | $180 (810 centres) |
| Shoulder or other arm joint MRI without contrast CPT 73221 · 181 Medicare scans | $104 | $696 | $190 (668 centres) |
| Knee or other leg joint MRI without contrast CPT 73721 · 217 Medicare scans | $100 | $692 | $187 (733 centres) |
| Abdomen and pelvis CT with contrast CPT 74177 · 446 Medicare scans | $156 | $761 | $286 (419 centres) |
| Abdominal ultrasound, complete CPT 76700 · 343 Medicare scans | $69 | $235 | $109 (647 centres) |
| Screening mammogram, both breasts CPT 77067 · 1,670 Medicare scans | $119 | $450 | $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.

- 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.
