Credentials and Medicare

State licence
LicenceStateSpecialty
W4647 TX Ophthalmology Physician primary

This provider holds licence W4647 issued in TX. A licence number in NPPES reflects what was filed at registration — it does not confirm the licence is still active today.

Medicare (PECOS)
Status
Approved
Provider type
Practitioner - Ophthalmology
PAC ID

Enrolled in Medicare 2 times, across 2 states:

StateEnrollment IDProvider type
Illinois I20260213001960 Practitioner - Ophthalmology
Texas I20260513003912 Practitioner - Ophthalmology

Medicare enrolment is recorded as approved under the provider type Practitioner - Ophthalmology. There are 2 separate enrolment records across 2 states (IL, TX). 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 Ophthalmology covers

An ophthalmologist has the knowledge and professional skills needed to provide comprehensive eye and vision care. Ophthalmologists are medically trained to diagnose, monitor and medically or surgically treat all ocular and visual disorders. This includes problems affecting the eye and its component structures, the eyelids, the orbit and the visual pathways. In so doing, an ophthalmologist prescribes vision services, including glasses and contact lenses. NUCC Health Care Provider Taxonomy, code 207W00000X
Allopathic & Osteopathic Physicians ›Ophthalmology

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-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

1003554015 passes the NPI check digit test The final digit 5 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 0 0 3 5 5 4 0 1
Doubled? — ×2 — ×2 — ×2 — ×2 — ×2 — ×2 — ×2
Value 8 0 8 8 0 2 0 0 3 1 5 8 0 2

Sum = 45 · next multiple of 10 = 50 · check digit = 5 · actual last digit = 5

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.
