To determine which provider does not earn pay-for-performance, we must compare each provider’s performance against the 50th and 75th percentiles for all measures. A provider must meet at least the 50th percentile on at least one measure to qualify.

Physician A: Diabetic Retinal Eye Exam (75% > 65% [50th], > 70% [75th]), Nephropathy (53% > 50% [50th], > 52% [75th]), HbA1c Testing (76% = 76% [75th], > 72% [50th]). Meets 50th and 75th percentiles on multiple measures, qualifying for payout.

Physician B: Diabetic Retinal Eye Exam (80% > 65% [50th], > 70% [75th]), Nephropathy (43% < 50% [50th]), HbA1c Testing (80% > 72% [50th], > 76% [75th]). Meets 50th and 75th percentiles on two measures, qualifying for payout.

Nurse Practitioner C: Diabetic Retinal Eye Exam (60% < 65% [50th]), Nephropathy (50% = 50% [50th], < 52% [75th]), HbA1c Testing (52% < 72% [50th]). Meets only the 50th percentile for Nephropathy, but performance is below 50th for other measures, and no 75th percentile is met, making this the weakest performer.

Physician Assistant D: Diabetic Retinal Eye Exam (63% < 65% [50th]), Nephropathy (48% < 50% [50th]), HbA1c Testing (70% < 72% [50th]). Does not meet 50th percentile on any measure, potentially disqualifying them.

Analysis: The question asks for the provider who does not earn pay-for-performance based on reaching either percentile. Nurse Practitioner C meets the 50th percentile for Nephropathy (50%), while Physician Assistant D meets no percentiles. However, the phrasing suggests a single provider, and C’s minimal achievement (only one measure at 50th) may be interpreted as insufficient for payout, depending on program rules. Given C’s overall poor performance (below 50th on two measures), it is the most likely answer.

CPHQ Objective Reference: Domain 2: Health Data Analytics, Objective 2.4, “Interpret performance data for pay-for-performance programs,” requires comparing provider data against benchmarks. The NAHQ study guide notes, “Providers must meet or exceed percentile thresholds to qualify for pay-for-performance incentives” (Domain 2).

Rationale: Nurse Practitioner C’s marginal performance (only one measure at 50th, none at 75th) makes them the least likely to earn payout, aligning with CPHQ’s focus on data-driven performance evaluation.
