Overall MIPS Quality Performance

The Merit-based Incentive Payment System (MIPS) is a way providers could use to participate in Medicare's 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.

MIPS Measure Score Weight Score
Quality 40% 82.8
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 (PI) 25% 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 15% 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 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 20% 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.
MIPS Final Score - 88
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.

NPI Validation Check Digit Calculation


The following table explains the step by step NPI number validation process using the ISO standard Luhn algorithm.

Start with the original NPI number, the last digit is the check digit and is not used in the calculation.
1487634861
Step 1: Double the value of the alternate digits, beginning with the rightmost digit.
241671238812
Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24.
2 + 4 + 1 + 6 + 7 + 1 + 2 + 3 + 8 + 8 + 1 + 2 + 24 = 69
Step 3: Subtract the total obtained in step 2 from the next higher number ending in zero, the result is the check digit.
70 - 69 = 11

The NPI number 1487634861 is valid because the calculated check digit 1 using the Luhn validation algorithm matches the last digit of the original NPI number.
