Medicare enrolment is recorded as approved under the provider type Part B Supplier - Clinic/group Practice. There are 14 separate enrolment records across 12 states (IA, CA, PA, TX, NC, AZ, WV, FL, MO, GA, IL, KY). 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.
What General Acute Care Hospital covers
An acute general hospital is an institution whose primary function is to provide inpatient diagnostic and therapeutic services for a variety of medical conditions, both surgical and non-surgical, to a wide population group. The hospital treats patients in an acute phase of illness or injury, characterized by a single episode or a fairly short duration, from which the patient returns to his or her normal or previous level of activity. NUCC Health Care Provider Taxonomy, code 282N00000X
The taxonomy records how the provider classifies their own practice. It does not confirm which conditions they currently treat, whether they are accepting new patients, or which insurance they take — call the office for that.
Full NPPES record
An NPI-2 identifies an organization — a clinic, hospital, group practice, laboratory, or supplier. Individual clinicians working there hold their own NPI-1 numbers separately, so a bill may reference both.

Number check
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 | 4 | 7 | 7 | 5 | 3 | 9 | 4 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 4 | 5 | 7 | 1 | 3 | 9 | 4 | 9 |
Sum = 68 · next multiple of 10 = 70 · check digit = 2 · actual last digit = 2
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.
