MIPS Score Distribution by Participation Type (PY2023)
Score band analysis of 477,137 clinicians in the CMS Quality Payment Program — performance year 2023. National mean, median, high-performer share, and payment penalty exposure.
Contents · 6 sections
Executive Summary
- 477,137 clinicians have a final MIPS score in CMS QPP Performance Year 2023 — the most comprehensive public view of physician quality measurement in the U.S.
- The national mean final score is 83.06 and the median is 85.49, indicating most clinicians cluster above the high-performer threshold of 75.
- 85.5% of clinicians scored at or above 75 — CMS's high-performer threshold — earning a positive payment adjustment.
- 2.4% of clinicians (11,289) scored below 18.75, the 2023 payment penalty threshold, and face a downward Medicare payment adjustment.
- MIPS score distribution is heavily left-skewed: the penalty and low-performer bands together represent only 3.9% of participating clinicians.

Key findings
Overview
The MIPS Score Distribution study analyzes final composite scores for 477,137 clinicians participating in the CMS Quality Payment Program (QPP) under the Merit-based Incentive Payment System (MIPS) for Performance Year 2023.
Why it matters: MIPS scores directly affect Medicare payment adjustments — clinicians below the penalty threshold face reduced reimbursements, while high performers can earn bonuses. The distribution of scores reveals how the program's incentive structure plays out across U.S. physicians and practitioners.
Score bands:
- High performer (≥ 75): 407,728 clinicians (85.5%) — eligible for a positive payment adjustment
- Average performer (45–74.99): 50,962 clinicians (10.7%)
- Low performer (18.75–44.99): 7,158 clinicians (1.5%)
- Penalty track (< 18.75): 11,289 clinicians (2.4%) — subject to a negative payment adjustment
What this data is not: MIPS scores measure administrative participation and reported quality metrics within the QPP program structure. A high MIPS score reflects documentation and reporting completeness, not necessarily clinical outcomes. See Limitations.
Data source
CMS Quality Payment Program (QPP) Individual Clinician Performance Data — Performance Year 2023. Public domain under 17 U.S.C. § 105. Downloaded from qpp.cms.gov.
Key fields used: npi (10-digit National Provider Identifier), final_score (composite MIPS score 0–100), quality_score, cost_score, ia_score (Improvement Activities), pi_score (Promoting Interoperability), payment_adjustment_pct.
Methodology version: cms-qpp-mips/v1 (pinned constant; never runtime-derived).
Limitations
Participation type not available in current data. The participation_type column (individual / group / facility-based) is not populated in the PY2023 QPP dataset as ingested. A full specialty cross-tab requires joining cms_qpp_mips_individual with NPPES taxonomy codes by NPI — flagged as §sprint3-mips-nppes-join for a future wave. Until that join is available, this study analyzes score distribution across all participating clinicians, not by specialty.
MIPS ≠ quality of care. MIPS scores reflect compliance with QPP reporting requirements and selected quality measures. A low MIPS score may indicate non-participation, exemptions (small practice, extreme hardship), or administrative gaps — not necessarily poor care.
PY2023 fixed snapshot. Data reflects CMS QPP release for Performance Year 2023. Scores do not update intra-year.
PHI note: Only aggregated statistics are presented. No individual NPI, clinician name, or practice location is included in this study's output.
Limitations
- This study's findings are scoped to the dataset and time window described in the methodology. They do not constitute medical, legal, or financial advice.
- Fonteum does not independently rate, inspect, verify, endorse, or guarantee any provider referenced in this study.

Final composite MIPS scores sourced from CMS QPP Individual Performance Data, Performance Year 2023. Score bands follow CMS payment adjustment thresholds: penalty track < 18.75; low performer 18.75–44.99; average performer 45–74.99; high performer ≥ 75. National mean and median computed over all 477,137 records with a non-null final_score. Methodology version: cms-qpp-mips/v1.
