What the Record Tells You
Sankararao Tamtam, MD, PA is an NPI registry record for a radiology clinic/centre at 936 S Hwy 123 Bypass in Seguin, Texas 78155. CMS issued NPI 1730475153 on 23 June 2011, and the organisation last updated its own entry on 23 June 2011. That was 15 years ago, so treat the phone number and suite as unverified until you have spoken to someone there.
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.
Seguin sits in the San Antonio-New Braunfels, TX metropolitan area (Guadalupe County), which has 75 imaging-centre records on the Texas side in the August 2026 file, 18 of them with the MRI code, out of 1,325 across Texas. The nearest alternatives in the registry are Guadalupe Valley Radiology, P.A. (0.7 miles, Seguin), Crossing Imaging Center LLC (11 miles, New Braunfels) and American Health Imaging of Dallas, LLC (11 miles, New Braunfels), with 2 more within 14 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 San Antonio-New Braunfels run from $1,379.73 (CHRISTUS Santa Rosa Hospital - Westover Hills) to $9,342.89 (Methodist Hospital Westover Hills) for a brain MRI without contrast, from the hospitals' federal transparency files. This centre's own prices are not in the registry: call (830) 379-1199 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.
