What the Record Tells You
Alliance MRI of Katy is an NPI registry record for an MRI centre at 21800 Katy Freeway, Suite 140 in Katy, Texas 77449. CMS issued NPI 1063960821 on 21 September 2016, 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 one imaging taxonomy code: Magnetic Resonance Imaging (MRI) clinic/center (261QM1200X). 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.
Katy sits in the Houston-Pasadena-The Woodlands, TX metropolitan area (Harris County), which has 396 imaging-centre records on the Texas side in the August 2026 file, 75 of them with the MRI code, out of 1,325 across Texas. The nearest alternatives in the registry are Ag Radiology Imaging Center, LLC (1.0 miles, Katy), Ag Radiology PLLC (1.0 miles, Katy) and Infinity MRI & Diagnostics - Ilp (1.6 miles, Houston), with 2 more within 1.9 miles.
For a cash-pay benchmark, our Texas range is $500 to $1,400 at freestanding imaging centres and $1,700 to $5,100 at hospitals for a typical single-region MRI. 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) 468-3842 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 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.
