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: Dermatology
Taxonomy Code: 207N00000X
Type: Allopathic & Osteopathic Physicians
License No.: A136567
License State: CA
Taxonomy Description: A dermatologist is trained to diagnose and treat pediatric and adult patients with benign and malignant disorders of the skin, mouth, external genitalia, hair and nails, as well as a number of sexually transmitted diseases.

Overall MIPS Quality Performance

The provider participated in CMS Quality Payment Program under the Merit-based Incentive Payment System (MIPS) and has an overall final score of 100, based on four performance areas: quality, improvement activities, promoting interoperability, and cost. The purpose of this information is to help people with Medicare make informed decisions and incentivize doctors and clinicians to maximize performance.

The Merit-based Incentive Payment System (MIPS) is a way providers could use to participate in CMS Quality Payment Program (QPP). The MIPS program affects clinician reimbursement for Part B covered professional services and also rewards them for improving the quality of patient care and outcomes.

Final Score: 100 out of 100

The MIPS program evaluates providers across multiple categories with a specific weight for each category resulting a in a MIPS final score that ranges from 0 to 100 points. The MIPS Final Score determines whether providers receive a negative, neutral or positive MIPS payment adjustment.
Quality Score: 100

The Quality category assesses providers performance on clinical practices and patient outcomes under the traditional MIPS program. The quality measures help identify the quality of healthcare processes, outcomes, and patient experiences. The Quality measure category compromises 40% providers final MPIS scores.

Promoting Interoperability Score: 100

The Interoperability category measures the providers ability to use technology to exchange and make use of healthcare information in a way that is less burdensome and improves outcomes. The Interoperability measure category compromises 25% providers final MPIS scores.

The MIPS Interoperability measure focuses on the use of certified electronic health record technology (CEHRT) to improve patient access health information, the exchange of information between clinicians and pharmacies and the systematic collection, analysis, and interpretation of healthcare data.
Improvement Activities Score: 40

The Improvement Activities performance category evaluates the providers participation in clinical activities that support the improvement of clinical practice, care delivery, and outcomes. Providers have the option to choose 2 to 4 activities from an inventory of over 100 improvement activities. Providers typically choose the activities that best fit their needs. The improvement activities measure category compromises 15% providers final MPIS scores.

The Improvement measures aim to better patient engagement, patient safety and other areas of patient care. The Improvement Activities category compromises 15% of providers final MPIS scores.
Cost Score: N/A

The Cost performance category asses the amount and types of services provided and how clinicians coordinate care and seek improvement of health outcomes by ensuring patients receive the appropriate services.

Although providers don't determine the price of healthcare services they are important in delivering high-quality care at a reasonable cost. The Cost measures category compromises 20% of providers final MPIS scores.

Quality Reporting

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 1194055699, we treat the final digit (9) 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 61. The final step is to find the difference between that total and the next multiple of ten (70 - 61 = 9).

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.

Check

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 9 → 18 → 9 0 → 0 5 → 10 → 1 9 → 18 → 9

Step 2: Add all digits plus the NPI constant

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

2 + 1 + 1 + 8 + 4 + 0 + 5 + 1 + 0 + 6 + 1 + 8 + 24 = 61

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

The next multiple of ten after 61 is 70. The difference is the calculated check digit.

70 - 61 = 9

This NPI is valid

The calculated check digit is 9, which matches the last digit of 1194055699.
