Specialty - Primary Taxonomy

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: Genetic Counselor, MS
Taxonomy Code: 170300000X
Type: Other Service Providers
Taxonomy Description: A masters trained health care provider who collects and interprets genetic family histories; assesses the risk of disease occurrence or recurrence; identifies interventions to manage or ameliorate disease risk; educates about inheritance, testing, management, prevention, ethical issues, resources, and research; and counsels to promote informed choices and adaptation. Certification was established in 1993 by the American Board of Genetic Counseling and prior to that by the American Board of Medical Genetics. Requirements for experience, licensure, and job responsibilities vary among the states.

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	0	9	9	1	5	5	1	1
Step 1: Double the value of the alternate digits, beginning with the rightmost digit.
2	6	0	9	18	1	10	5	2
Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24.
2 + 6 + 0 + 9 + 1 + 8 + 1 + 1 + 0 + 5 + 2 + 24 = 59
Step 3: Subtract the total obtained in step 2 from the next higher number ending in zero, the result is the check digit.
60 - 59 = 1									1

The NPI number 1609915511 is valid because the calculated check digit 1 using the Luhn validation algorithm matches the last digit of the original NPI number.
