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: Behavior Technician
Taxonomy Code: 106S00000X
Type: Behavioral Health & Social Service Providers
Taxonomy Description: The behavior technician is a paraprofessional who practices under the close, ongoing supervision of a behavior analyst or assistant behavior analyst certified by the Behavior Analyst Certification Board and/or credentialed by a state (such as through licensure). The behavior technician is primarily responsible for the implementation of components of behavior-analytic treatment plans developed by the supervisor. That may include collecting data on treatment targets and conducting certain types of behavioral assessments (e.g., stimulus preference assessments). The behavior technician does not design treatment or assessment plans or procedures but provides services as assigned by the supervisor responsible for his or her work.

CLIA Information

The Clinical Laboratory Improvement Amendments (CLIA) of 1988 applies to facilities or sites that test human specimens for health assessment or to diagnose, prevent, or treat disease. The CLIA Program sets standards for clinical laboratory testing and issues certificates. The NPI / CLIA crosswalk information for this NPI number is:

CLIA Number: 49D0871627
Facility Type: Other
Certificate Effective Date: June 04, 2025
Certificate Expiration Date: June 03, 2027
Laboratory Director: MERRY BRINKLEY
Certificate Type: Certificate of Waiver
Certificate Type Description: This CLIA certificate is issued to Alexandria Da'costa to perform only waived tests. CLIA defines waived tests as simple tests with a low risk for an incorrect result. Waived tests include certain tests listed in CLIA regulations, tests cleared by the FDA for home use and tests approved by the FDA for waived status and that meet CLIA waiver criteria.

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 1346853496, we treat the final digit (6) 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 74. The final step is to find the difference between that total and the next multiple of ten (80 - 74 = 6).

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.

Target digit

Regular digit Doubled digit Check digit

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 4 → 8 8 → 16 → 7 3 → 6 9 → 18 → 9

Step 2: Add all digits plus the NPI constant

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

2 + 3 + 8 + 6 + 1 + 6 + 5 + 6 + 4 + 1 + 8 + 24 = 74

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

The next multiple of ten after 74 is 80. The difference is the calculated check digit.

80 - 74 = 6

This NPI is valid

The calculated check digit is 6, which matches the last digit of 1346853496.
