A primary care provider (PCP) like James Gardner sees people with common medical problems. The primary care provider might be a doctor, physician assistant, nurse practitioner or clinic that are usually involved in your long-term care. A PCP might provide preventive care, treat common medical conditions, identify urgent medical problems and refer you to specialists when necessary. Primary care is usually provided in an outpatient facility but if you are admitted to a hospital your PCP may assist in your care. The most common medical conditions seen by primary care providers are: hypertension, upper respiratory tract infections, depression or anxiety, back pain, arthritis, dermatitis, diabetes, urinary tract infections, etc .

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. James Gardner opted out of Medicare effective on 10-01-2015 until 10-01-2027. 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 but is permitted to 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 1255447330, we treat the final digit (0) 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 60. The final step is to find the difference between that total and the next multiple of ten (60 - 60 = 0).

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 5 → 10 → 1 4 → 8 7 → 14 → 5 3 → 6

Step 2: Add all digits plus the NPI constant

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

2 + 2 + 1 + 0 + 5 + 8 + 4 + 1 + 4 + 3 + 6 + 24 = 60

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

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

60 - 60 = 0
This NPI is valid
The calculated check digit is 0, which matches the last digit of 1255447330.
