An acupuncturist like Hwiyoung Oh specializes in diagnosing, treating, and preventing some diseases using acupuncture needles. Acupuncturists carefully insert and manipulate fine, solid needles at specific points on the skin to achieve therapeutic benefits. Modern medicine explains that acupuncture works by stimulating the nervous system, causing the body to release certain chemicals, including endorphins, in the muscles, spinal cord, and brain. These chemicals assist the body in managing and regulating pain. Other commonly used treatment methods in acupuncture include herbs or mixtures of herbs, and acupressure, which involves massaging acupuncture points instead of using needles.

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 1821938887, we treat the final digit (7) 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 73. The final step is to find the difference between that total and the next multiple of ten (80 - 73 = 7).
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 73 is 80. The difference is the calculated check digit.
