What the Record Tells You

Horizon Three LLC is an NPI registry record for an MRI centre at 520 D St, Ste B in Clearwater, Florida 33756. CMS issued NPI 1992708101 on 23 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.

Clearwater sits in the Tampa-St. Petersburg-Clearwater, FL metropolitan area (Pinellas County), which has 329 imaging-centre records on the Florida side in the September 2026 file, 47 of them with the MRI code, out of 2,076 across Florida. The nearest alternatives in the registry are Advantage Out Patient Imaging Center (0.0 miles, Clearwater), Musculoskeletal Institute Chartered (0.3 miles, Clearwater) and Radiology Associates of Clearwater (0.4 miles, Clearwater), with 2 more within 0.6 miles.

For a cash-pay benchmark, our Florida freestanding-centre estimate is $500 to $1,500 for a typical single-region MRI. At Florida hospitals the cash price is measured rather than estimated: $243 to $4,532 for a brain MRI, median $1,360, from 39 of the 73 Florida hospitals whose own price files we have read, out of 167 in the state, files dated to September 2026. Published hospital cash prices in Tampa-St. Petersburg-Clearwater run from $1,522.15 (Tampa General Hospital) to $1,522.15 (Tampa General Hospital) for a brain MRI without contrast, from the hospitals' federal transparency files. This centre's own prices are not in the registry: call (727) 466-9361 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 Florida: 39 hospitals measured

Freestanding imaging centre, estimated

$500 to $1,500

Our own estimate. No imaging operator publishes a per-state cash price.

Hospital outpatient, measured

$243 to $4,532

Median $1,360 cash against a median gross charge of $4,831, from 39 of the 73 Florida hospitals whose own price files we have read, out of 167 in the state, files dated to September 2026.

Strong independent imaging centre network statewide; Miami metro priced higher. 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 32 hospitals publish a “cash price” that is its chargemaster restated rather than a discount, reaching $18,295; those are kept out of the band above and counted here instead. 1 more hospital lists this code at prices more than three times apart in the same file, from $1,283 to $1,283, 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).

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.

Full list: cheap MRI, good MRI checklist.
