Documented Medicare service activity
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.
