Medicare enrolment is recorded as approved under the provider type Practitioner - Diagnostic Radiology. There are 22 separate enrolment records across 22 states (MO, KS, CA, TX, GA, AZ, IL, NM, NC, OH, FL, NY, DE, PA, SC, AL, TN, NH, NJ, WA, NV, MI). Multiple enrolments usually mean the provider bills Medicare from more than one practice location, or has kept an earlier enrolment after moving. Each record carries its own enrolment ID, listed above. Being enrolled means the provider can bill Medicare; it does not tell you whether they are currently accepting new Medicare patients. Call the office to confirm.

Licensed in 8 states

This provider holds licences in 8 states: Delaware, Florida, Illinois, Kansas, Missouri, New Mexico, Virginia and Washington. The practice address on file is in Rockford, IL, but a licence in another state usually means they see patients there too — either at a second location or by telehealth. If the address above is far from you, it is worth calling to ask whether they practise closer to where you live.

Full NPPES record

An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

Number check

1518946649 passes the NPI check digit test The final digit 9 matches the value computed from the first nine digits, so this is a well-formed NPI.
How the check works, step by step

Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.

Digit 8 0 8 4 0 1 5 1 8 9 4 6 6 4
Doubled? ×2 ×2 ×2 ×2 ×2 ×2 ×2
Value 8 0 8 8 0 2 5 2 8 9 4 3 6 8

Sum = 71 · next multiple of 10 = 80 · check digit = 9 · actual last digit = 9

A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
