Psychiatric Residential Treatment Facility
- Taxonomy Code
- 323P00000X
- Type
- Residential Treatment Facilities
- Taxonomy Description
- A residential treatment facility (RTF) is a facility or distinct part of a facility that provides to children and adolescents, a total, twenty-four hour, therapeutically planned group living and learning situation where distinct and individualized psychotherapeutic interventions can take place. Residential treatment is a specific level of care to be differentiated from acute, intermediate, and long-term hospital care, when the least restrictive environment is maintained to allow for normalization of the patient's surroundings. The RTF must be both physically and programmatically distinct if it is a part or subunit of a larger treatment program. An RTF is organized and professionally staffed to provide residential treatment of mental disorders to children and adolescents who have sufficient intellectual potential to respond to active treatment (that is, for whom it can reasonably be assumed that treatment of the mental disorder will result in an improved ability to function outside the RTF) for whom outpatient treatment, partial hospitalization or protected and structured environment is medically or psychologically necessary

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 1003591397, we treat the final digit (7) 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 53. The final step is to find the difference between that total and the next multiple of ten (60 - 53 = 7).
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.
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.
Step 2: Add all digits plus the NPI constant
Add the transformed values, the unchanged digits, and the constant 24.
Step 3: Find the amount needed to reach the next multiple of 10
The next multiple of ten after 53 is 60. The difference is the calculated check digit.
