What is PECOS?
PECOS is the online Medicare enrollment management system or Provider, Enrollment, Chain and Ownership System. The PECOS system is a database of providers who have registered with CMS as providers or suppliers. PECOS is the primary source of information about verified Medicare professionals. Providers that want to participate in this program need to enroll in PECOS with their NPI number to avoid denied claims.

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 75, 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: 75 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: N/A

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.

There are six collection types for MIPS quality measures: Electronic Clinical Quality Measures (eCQMs), MIPS Clinical Quality Measures (CQMs), Qualified Clinical Data Registry (QCDR) Measures, Medicare Part B claims measures, CMS Web Interface measures and The Consumer Assessment of Healthcare Providers and Systems (CAHPS) for MIPS Survey.
Promoting Interoperability Score: N/A

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: N/A

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.

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 1831184753, we treat the final digit (3) 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 67. The final step is to find the difference between that total and the next multiple of ten (70 - 67 = 3).

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 3 → 6 1 → 2 4 → 8 5 → 10 → 1

Step 2: Add all digits plus the NPI constant

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

2 + 8 + 6 + 1 + 2 + 8 + 8 + 7 + 1 + 0 + 24 = 67

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

The next multiple of ten after 67 is 70. The difference is the calculated check digit.

70 - 67 = 3

This NPI is valid

The calculated check digit is 3, which matches the last digit of 1831184753.
