What the Record Tells You
One Step Diagnostic VIII LP is an NPI registry record for a radiology clinic/centre at 2401 Fm 646 Rd W Ste B in Dickinson, Texas 77539. CMS issued NPI 1508153818 on 7 July 2011, and the organisation last updated its own entry on 6 November 2024. That is recent, so the contact details are likely current.
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.
Dickinson sits in the Houston-Pasadena-The Woodlands, TX metropolitan area (Galveston 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 Advantis MRI & Diagnostics LLC (0.0 miles, Dickinson), Horizon Texas City LLC (3.6 miles, Texas City) and A1 Imaging of Texas City (3.6 miles, Texas City), with 2 more within 4.5 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 (281) 534-3700 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 One Step Diagnostic VIII LP (NPI 1508153818). 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 |
|---|---|---|---|
| Chest X-ray, 2 views CPT 71046 · 37 Medicare scans | $33 | $600 | $31 (743 centres) |
| Chest CT without contrast CPT 71250 · 14 Medicare scans | $131 | $2,900 | $124 (492 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.
