Medicare enrolment is recorded as approved under the provider type Practitioner - Peripheral Vascular Disease. This means the provider is enrolled to bill Medicare, though it does not tell you whether they are currently accepting new Medicare patients. Call the office to confirm.
Licensed in 2 states
This provider holds licences in 2 states: Colorado and Texas. The practice address on file is in Arlington, TX, 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.
Licence numbers are self-reported to NPPES at registration. They do not confirm a licence is currently active, in good standing, or valid for the specialty shown — only the state board can tell you that, which is why we link to each one.
What Phlebology covers
Phlebology is the medical discipline that involves the diagnosis and treatment of venous disorders, including spider veins, varicose veins, chronic venous insufficiency, venous leg ulcers, congenital venous abnormalities, venous thromboembolism and other disorders of venous origin. A phlebologist has attained a minimum of 50 hours of CME units in phlebology-related courses, and is knowledgeable of and trained in a variety of diagnostic techniques including physical examination, venous imaging techniques such as duplex ultrasound, CT and MR, plethysmographic techniques and laboratory evaluation related to venous thromboembolism. The phlebologist is also trained in a variety of therapeutic interventions, which may include compression, sclerotherapy, cutaneous vascular laser, endovenous thermoablation procedures (laser and radiofrequency) endovenous chemical ablation, surgical procedures (e.g., ambulatory phlebectomy, venous ligation), vasoactive medications and the management of venous thromboembolism.

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
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 | 5 | 7 | 5 | 9 | 8 | 4 | 4 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 4 | 1 | 7 | 1 | 9 | 7 | 4 | 8 |
Sum = 67 · next multiple of 10 = 70 · check digit = 3 · actual last digit = 3
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.
