A psychologist like Duane Alleman studies cognitive, emotional, social processes and behavior by observing, interpreting, and recording how people relate to one another and to their environments. Psychologists gather information and evaluate behavior through controlled laboratory experiments, psychoanalysis, psychotherapy or through personality, performance, aptitude, or intelligence tests, and use this information when testing theories in their research or when treating patients.
The provider doesn't accept Medicare and has signed an affidavit to be excluded from the Medicare program. If you are a Medicare beneficiary this means a provider can charge whatever they want for services rendered but must follow certain rules to do so. Duane Alleman opted out of Medicare effective on 10-01-2020 until 10-01-2026. Opt out periods last for two years and cannot be terminated unless the provider is opting out for the very first time and the affidavit is terminated no later than 90 days after the opt out effective date. Opt-out affidavits might renew automatically renew every two years. The provider opted out of Medicare and cannot order and refer services to other healthcare providers.

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 1013031228, we treat the final digit (8) 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 42. The final step is to find the difference between that total and the next multiple of ten (50 - 42 = 8).
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 42 is 50. The difference is the calculated check digit.
