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.

No individual clinical measures approved by CMS for profile display are available for this doctor in this release. Missing results do not mean poor care. Many clinicians or measures are not publicly reported.

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.

No procedure activity is available for display in this release. This does not mean this doctor has no experience.

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

No group survey results are linked in this release. Missing information is not a judgment about this doctor’s care.
