CMS measures of specific care

These are 2024 results reported for this clinician’s NPI. Each CMS rating describes one measure of care, not patient reviews or an overall doctor grade. The patients, ages and insurance types included depend on the measure and collection method; these are not necessarily Medicare-only or pediatric results. They do not establish performance at a particular current practice.

CMS assigns 1–5 stars using a separate benchmark for the measure, reporting entity and collection method. Higher ratings indicate better reported performance on that measure. Five stars means the CMS benchmark was met; it does not mean every patient had a good outcome. Ratings should not be averaged across measures.

Lower raw performance rates are better for this measure. Higher CMS ratings are better; the rating above already accounts for the inverse direction.

Measure MIPS_EC_318_overall · Performance year 2024

Released 2026-09-10. Only CMS display-approved MIPS and QCDR clinical measures are shown; participation attestations and cost measures are excluded. CMS uses a benchmark drawn from best performers covering at least 10% of the relevant patient population, with an adjustment for small denominators. ModernDoc has not independently validated these ratings. Source data and reported rates · CMS rating methodology · Coverage and reporting limits.

Reported procedure activity

CMS attributes these procedures to this clinician through Original Medicare and Medicare Advantage claims and encounters. Counts span locations and are not unique-patient counts. They do not establish quality, current availability, or that a procedure is offered at any practice listed here. Other insurance populations are not included.

CMS release 2026-10-15. CMS describes a 12-month observation window with a three-month claims-processing lag; this file does not provide exact start and end dates. Only categories CMS marks for profile display are shown. Source data · How CMS reports procedures.

Patient experience at affiliated groups

These are 2024 survey results for the groups below, not ratings of this doctor. We matched group IDs to affiliation records released 2026-10-15; that does not establish this doctor’s membership during the survey year.

CMS sampled patients with traditional Medicare (fee-for-service), aged 18 or older, who had at least two visits to the group. These results do not describe children’s experiences or all patients and insurance types. Percentages describe respondents choosing the most positive survey response; each measure has its own patient denominator. They do not measure clinical accuracy or current appointment availability.
