General Payments changed from PY2023 to PY2024
Ardelyx, Inc.'s CMS-reported General Payments increased by $417.1K (+29.9%) from PY2023 to PY2024.
How this year-over-year comparison is scoped
The comparison uses consecutive CMS program years only (current = prior + 1) from the manufacturer General Payments summary and excludes research and ownership or investment records. Non-consecutive year pairs are not shown as year-over-year change. This General Payments figure is not the all-tracks company total in the hero.
CMS source labels for this exact identifier: PY2022: ARDELYX, INC.PY2023: ARDELYX, INC.PY2024: Ardelyx, Inc.. Matching identifiers support a bounded record comparison; a label difference would be reported as unresolved rather than treated as a corporate event.

What the Data Shows for Ardelyx, Inc.
The all-tracks total above combines three CMS reporting categories - General Payments, Research Payments, and Ownership/Investment interests - not one undifferentiated figure. For Ardelyx, Inc., that total blends General Payments (day-to-day consulting, meals, travel and speaking fees, shown separately above) with Research and Ownership/Investment interest records, each governed by its own CMS reporting rules. CMS publishes each Program Year's data roughly 12 months after the reporting period ends, so this reflects the most recently released cycle; see our methodology for how the tracks are standardized and compared across companies.
"Food and Beverage" leads the 6-category general-payment breakdown below at $1.0M (56.6% of General Payments, 41,754 transactions) - see our methodology for how research and ownership payments are reported separately.
