Wholesale Acquisition Cost (WAC) Increase Report Data – Current Year
Q1 was the only quarter in 2023 in which the median cumulative WAC percent increase for all drug price categories was below the yearly median (21.1 percent).
HCAI collects and publishes information on prescription drugs with a Wholesale Acquisition Cost (WAC) increase exceeding a specified threshold.
The visualizations below include submitted WAC increase data from Q1 2023 through Q4 2023. These graphs display data that shows Median Cumulative WAC Percent Increase by WAC Price Category, Drug Source Type, or Both. The visualizations allow you to filter through the data by quarter.

How HCAI Created This Product
Prescription Drug WAC Increase data for 2023 from the Cost Transparency: Prescription Drug Program (CTRx).
Note: Reported increases that do not meet the statutory requirements for reporting and prescription drugs that do not meet the definition for reporting under the program regulations and Section 321(g) of Title 21 of the United States Code were not included in the visualizations. Submitted reports not meeting statutory requirements were 34 of 1,507 (2.3 percent) in 2023. In addition, approximately 58 percent of reports in 2023 did not include any reason(s) for the reported WAC increases due to the information not already being in the public domain.
Resources
Note:
- The 3-year median percent increase is based on submitted WAC increase data. The dataset is subject to reporting.
- The dataset includes only complete reports submitted by manufacturers for WAC increases made in 2023 and does not include reports that do not meet the specified minimum thresholds for reporting.
- Late WAC reports submitted after February 13, 2024, are not included in the dataset.
