Before arranging a visit
Confirm current services, ages treated, insurance, location, hospital affiliations and appointment availability directly with the practice. An active NPI does not verify current licensure, certification or practice status.
A registry specialty label does not establish that a clinician currently provides the particular care you need.
Background and affiliations
Medicare quality score (MIPS)
87.5 out of 100 in Medicare’s Merit-based Incentive Payment System for 2024, reported by the practice group. MIPS reflects Medicare reporting on quality measures, cost and care practices; it does not measure surgical results or patient ratings. Medicare Care Compare

Documented Medicare service activity
For maternity care, confirm delivery services and the delivery hospital.
Reporting year: 2024. These are billed services or units in Original Medicare Part B, not total career experience, all patients, surgical case counts or a quality rating.
No publicly disclosed rows were found for this NPI in the complete 2024 CMS file. This does not mean no patients or procedures: low-volume rows are suppressed, and Medicare excludes much obstetric, pediatric and commercially insured care.
How to interpret these counts
CMS suppresses provider/service rows involving fewer than 11 beneficiaries. Services may repeat for one person, and beneficiaries cannot be added across rows. Facility/non-facility describes billing and does not establish a current hospital affiliation. These counts do not report case complexity, clinical outcomes or whether a treatment is appropriate for you.
