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: Speech-Language Pathologist
Taxonomy Code: 235Z00000X
Type: Speech, Language and Hearing Service Providers
License No.: 146018381
Taxonomy Description: The speech-language pathologist is the professional who engages in clinical services, prevention, advocacy, education, administration, and research in the areas of communication and swallowing across the life span from infancy through geriatrics. Speech-language pathologists address typical and atypical impairments and disorders related to communication and swallowing in the areas of speech sound production, resonance, voice, fluency, language (comprehension and expression), cognition, and feeding and swallowing.

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	8	2	1	9	8	9	8	9	8
Step 1: Double the value of the alternate digits, beginning with the rightmost digit.
2	8	4	1	18	8	18	8	18
Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24.
2 + 8 + 4 + 1 + 1 + 8 + 8 + 1 + 8 + 8 + 1 + 8 + 24 = 82
Step 3: Subtract the total obtained in step 2 from the next higher number ending in zero, the result is the check digit.
90 - 82 = 8									8

The NPI number 1821989898 is valid because the calculated check digit 8 using the Luhn validation algorithm matches the last digit of the original NPI number.
