What the Record Tells You

Sdr Diagnostics LLC, the trading name of Sdr Clinic and Sleep Disorder Institute LLC, is an NPI registry record for a radiology clinic/centre at 836 Ponce De Leon Blvd, Suite 202 in Coral Gables, Florida 33134. CMS issued NPI 1598716961 on 12 May 2006, and the organisation last updated its own entry on 7 May 2009. That was 17 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. It also holds one other taxonomy code (261QS1200X).

Coral Gables sits in the Miami-Fort Lauderdale-West Palm Beach, FL metropolitan area (Miami-Dade County), which has 825 imaging-centre records on the Florida side in the September 2026 file, 178 of them with the MRI code, out of 2,076 across Florida. The nearest alternatives in the registry are Miami Portable Diagnostics INC (0.1 miles, Coral Gables), Coral Gables MRI INC (0.1 miles, Coral Gables) and Jackson Diagnostic Center at Coral Gables (0.2 miles, Coral Gables), with 2 more within 0.3 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. This centre's own prices are not in the registry: call (305) 263-6820 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.
