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: 97.69 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.

  • 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.

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.
1427091016
Step 1: Double the value of the alternate digits, beginning with the rightmost digit.
244709202
Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24.
2 + 4 + 4 + 7 + 0 + 9 + 2 + 0 + 2 + 24 = 54
Step 3: Subtract the total obtained in step 2 from the next higher number ending in zero, the result is the check digit.
60 - 54 = 66

The NPI number 1427091016 is valid because the calculated check digit 6 using the Luhn validation algorithm matches the last digit of the original NPI number.
