Reviews for JOSHUA JEREMY POTHEN MD

  • 5 out of 5 stars - Review by Mary ***** on December 17, 2025

    My wife started seeing Dr Pothen in Nov 2025. He first made us feel really comfortable with him and showed us that he was very knowledgeable in his field. He explained in detail what our options were and told us what he thought would be the right way to go. It is early in her treatment but we both feel we have made the right decision on a doctor for the cancer she has. We can see he cares.

  • 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 1316441231, we treat the final digit (1) 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 59. The final step is to find the difference between that total and the next multiple of ten (60 - 59 = 1).

    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.

    1 → 2 1 → 2 4 → 8 1 → 2 3 → 6

    Step 2: Add all digits plus the NPI constant

    Add the transformed values, the unchanged digits, and the constant 24.

    2 + 3 + 2 + 6 + 8 + 4 + 2 + 2 + 6 + 24 = 59

    Step 3: Find the amount needed to reach the next multiple of 10

    The next multiple of ten after 59 is 60. The difference is the calculated check digit.

    60 - 59 = 1
    This NPI is valid
    The calculated check digit is 1, which matches the last digit of 1316441231.
