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: Psychiatry & Neurology Psychosomatic Medicine
Taxonomy Code: 2084P0015X
Type: Allopathic & Osteopathic Physicians
License No.: MD2026-0540
License State: NM
Taxonomy Description: Psychosomatic Medicine is subspecialty in the diagnosis and treatment of psychiatric disorders and symptoms in complex medically ill patients. This subspecialty includes treatment of patients with acute or chronic medical, neurological, obstetrical or surgical illness in which psychiatric illness is affecting their medical care and/or quality of life such as HIV infection, organ transplantation, heart disease, renal failure, cancer, stroke, traumatic brain injury, high-risk pregnancy and COPD, among others. Patients also may be those who have a psychiatric disorder that is the direct consequence of a primary medical condition, or a somatoform disorder or psychological factors affecting a general medical condition. Psychiatrists specializing in Psychosomatic Medicine provide consultation-liaison services in general medical hospitals, attend on medical psychiatry inpatient units, and provide collaborative care in primary care and other outpatient settings.

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 1265007256, 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 44. The final step is to find the difference between that total and the next multiple of ten (50 - 44 = 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.

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 6 → 12 → 3 0 → 0 7 → 14 → 5 5 → 10 → 1

Step 2: Add all digits plus the NPI constant

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

2 + 2 + 1 + 2 + 5 + 0 + 0 + 1 + 4 + 2 + 1 + 0 + 24 = 44

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

The next multiple of ten after 44 is 50. The difference is the calculated check digit.

50 - 44 = 6

This NPI is valid

The calculated check digit is 6, which matches the last digit of 1265007256.
