What the Record Tells You
Alliance MRI Montgomery County is an NPI registry record for an MRI centre and radiology clinic at 9851 Fm 1097 Rd W in Willis, Texas 77318. CMS issued NPI 1942839527 on 6 April 2020, and the organisation last updated its own entry on 21 July 2026. That is recent, so the contact details are likely current.
The record carries 3 imaging taxonomy codes: Diagnostic radiology (physician specialty code carried by an organisation) (2085R0202X) and Magnetic Resonance Imaging (MRI) clinic/center (261QM1200X) and Radiology clinic/center (261QR0200X). 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.
Willis sits in the Houston-Pasadena-The Woodlands, TX metropolitan area (Montgomery County), which has 440 imaging-centre records on the Texas side in the October 2026 file, 76 of them with the MRI code, out of 1,458 across Texas. The nearest alternatives in the registry are 3083 Imaging LLC (4.7 miles, Conroe), Memorial Hermann Imaging Centers-Conroe Center (6.0 miles, Conroe) and Lake Area Imaging and Diagnostics, A Department of Hca Houston Healthcare Conroe (8.8 miles, Montgomery), with 2 more within 9.5 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 Houston-Pasadena-The Woodlands run from $230.91 (Harris Health Ben Taub Hospital) to $20,243.66 (HCA Houston Healthcare Northwest) for a brain MRI without contrast, from the hospitals' federal transparency files. This centre's own prices are not in the registry: call (713) 955-5705 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 Alliance MRI Montgomery County (NPI 1942839527). 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 and with contrast CPT 70553 · 26 Medicare scans | $300 | $4,750 | $291 (588 centres) |
| Chest X-ray, 2 views CPT 71046 · 49 Medicare scans | $32 | $436 | $31 (743 centres) |
| Chest CT without contrast CPT 71250 · 29 Medicare scans | $125 | $1,750 | $124 (492 centres) |
| Cervical spine MRI without contrast CPT 72141 · 36 Medicare scans | $164 | $3,500 | $165 (719 centres) |
| Lumbar spine MRI without contrast CPT 72148 · 76 Medicare scans | $179 | $3,500 | $180 (810 centres) |
| Shoulder or other arm joint MRI without contrast CPT 73221 · 55 Medicare scans | $187 | $3,500 | $190 (668 centres) |
| Knee or other leg joint MRI without contrast CPT 73721 · 69 Medicare scans | $186 | $3,500 | $187 (733 centres) |
| Abdomen and pelvis CT with contrast CPT 74177 · 29 Medicare scans | $292 | $2,100 | $286 (419 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.

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.
