The NPI enumerator requires providers to submit at least one taxonomy code. A taxonomy code is a unique 10-character code that describes the healthcare provider type, classification, and the area of specialization. There could be only one primary taxonomy code per NPI record. For individual NPIs the license data is associated to the taxonomy code.

Classification: Registered Nurse
Taxonomy Code: 163W00000X
Type: Nursing Service Providers
License No.: 235947
License State: MA
Taxonomy Description: (1) A registered nurse is a person qualified by graduation from an accredited nursing school (depending upon schooling, a registered nurse may receive either a diploma from a hospital program, an associate degree in nursing (A.D.N.) or a Bachelor of Science degree in nursing (B.S.N.), who is licensed or certified by the state, and is practicing within the scope of that license or certification. R.N.'s assist patient in recovering and maintaining their physical or mental health. They assist physicians during treatments and examinations and administer medications. (2) A provider who is trained and educated in a formal nursing education program at an accredited school of nursing, passes a national certification examination, and is licensed by the state to practice nursing.

NPI Validation Check Digit Calculation

The following table explains the step by step NPI number validation process using the ISO standard Luhn algorithm.

Start with the original NPI number, the last digit is the check digit and is not used in the calculation.
1	6	4	9	4	9	7	9	7	5
Step 1: Double the value of the alternate digits, beginning with the rightmost digit.
2	6	8	9	8	9	14	9	14
Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24.
2 + 6 + 8 + 9 + 8 + 9 + 1 + 4 + 9 + 1 + 4 + 24 = 85
Step 3: Subtract the total obtained in step 2 from the next higher number ending in zero, the result is the check digit.
90 - 85 = 5									5

The NPI number 1649497975 is valid because the calculated check digit 5 using the Luhn validation algorithm matches the last digit of the original NPI number.
