How this page is built
- What is counted
- One row per registration in the register. This page is the row for this 340B ID; a figure that reads across a record and its locations counts the rows the register lists under this record as well.
- As of
- November 6, 2026 — the date of the register file this record was last listed in.
- Contract-pharmacy arrangements
- Each arrangement the register files between a covered entity and a pharmacy counts once. An arrangement counts among those with no end date where the register prints no termination date for it, and among the rest where it prints one.
Every figure on this page comes from HRSA 340B OPAIS Covered Entity Daily Report.
Every figure on this page is printed as it appears in the HRSA 340B OPAIS Covered Entity Daily Report, file 340B_CoveredEntity_Daily_20261106_071011.xlsx, stamped by its publisher November 6, 2026. This record has been read here since September 6, 2026.
