- Taxonomy Description
- 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.

NPI NPI Number Validation
How NPI Validation Works
The NPI validation process uses the ISO-standard Luhn algorithm, a mathematical "handshake", to ensure that a provider's 10-digit ID is authentic and free of common typing errors.
To verify the NPI 1730005505, we treat the final digit (5) as the Check Digit—the target answer we need to reach. The process begins by taking the first nine digits and adding a constant value of 24, which accounts for the "80840" prefix required for all U.S. health identifiers. We then double every other digit starting from the right and sum the individual digits of those results together. For this specific NPI, that total comes to 45. The final step is to find the difference between that total and the next multiple of ten (50 - 45 = 5).
Digit-by-digit view
Use the first nine digits for the calculation. Starting from the right, double every other digit. The last digit is the check digit and is not part of the calculation.
Step 1: Double every other digit from the right
Starting with the rightmost digit of the first nine digits, double every other value. If doubling creates a two-digit number, add those digits together.
Step 2: Add all digits plus the NPI constant
Add the transformed values, the unchanged digits, and the constant 24.
Step 3: Find the amount needed to reach the next multiple of 10
The next multiple of ten after 45 is 50. The difference is the calculated check digit.
