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.

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 | 3 | 3 | 1 | 8 | 9 | 9 | 1 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 6 | 3 | 2 | 8 | 9 | 9 | 2 |
Sum = 65 · next multiple of 10 = 70 · 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.
