What the Record Tells You

Horizon Open MRI of Las Colinas LLC, the trading name of Medfund LLC, is an NPI registry record for an MRI centre at 6550 N Macarthur Blvd, Ste 120 in Irving, Texas 75039. CMS issued NPI 1174526966 on 24 May 2005, and the organisation last updated its own entry on 22 August 2020. That was 6 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: 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. The same business holds 2 sibling registrations at this address under the names A1 Imaging of Dallas (NPI 1477713527) and A1 Imaging of Dallas (NPI 1538307426); they are covered by this page rather than given their own.

Irving sits in the Dallas-Fort Worth-Arlington, TX metropolitan area (Dallas County), which has 465 imaging-centre records on the Texas side in the September 2026 file, 99 of them with the MRI code, out of 1,450 across Texas. The nearest alternatives in the registry are Viascan (1.3 miles, Irving), Envision Imaging of Las Colinas (1.6 miles, Irving) and Clearvue Imaging Dallas, LLC (2.0 miles, Irving).

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 Dallas-Fort Worth-Arlington run from $1,362.00 (Parkland Memorial Hospital) to $6,582.88 (Medical City Dallas) for a brain MRI without contrast, from the hospitals' federal transparency files. This centre's own prices are not in the registry: call (972) 444-0100 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.

Cash-Price Benchmark

Cash price for a brain MRI in Texas: 125 hospitals measured

Freestanding imaging centre, estimated

$500 to $1,400
Our own estimate. No imaging operator publishes a per-state cash price.

Hospital outpatient, measured

$236 to $10,390
Median $2,190 cash against a median gross charge of $4,174, 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.

Houston, Dallas, Austin, San Antonio all competitive; Houston Methodist and MD Anderson at the top. 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 42 hospitals publish a “cash price” that is its chargemaster restated rather than a discount, reaching $23,252; those are kept out of the band above and counted here instead. 4 more hospitals list this code at prices more than three times apart in the same file, from $124 to $362, so which row is the scan cannot be told from the file; they are excluded from the band and counted here. Hospitals whose file we could not read are named, not filled in (methodology).

Parsed hospital cash prices for Dallas-Fort Worth-Arlington (brain MRI, CPT 70551): Parkland Memorial Hospital $1,362.00; Methodist Dallas Medical Center $2,324.00; Texas Health Presbyterian Hospital Dallas $2,504.25 and 1 more. Full table on the Dallas-Fort Worth-Arlington metro page.

What to ask when you call

  1. 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.
  2. Scanner field strength (1.5T or 3T) and whether it is closed, wide-bore or open.
  3. ACR or IAC accreditation, and who reads the images. The registry cannot tell you either.
  4. Whether they accept an order from a telehealth referral if you have no local doctor.
