A registry specialty label does not establish that a clinician currently provides the particular care you need.
Background and affiliations
Industry payments
No 2025 general payments from drug or device companies were reported for Koji Haratani. Research funding is excluded. These payments are public under the Sunshine Act, and a payment does not by itself mean a conflict of interest. CMS Open Payments

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.
