Notes and methodology
How the weekly brief calculations were ranked, aggregated, and preserved for archive consistency.
Publication comparison
Prices are compared between the two CMS publication dates shown above, using weekly history snapshots. An unchanged effective date does not mean a publication is missing. NDCs absent from the previous publication are excluded from change calculations; missing prices are not counted as unchanged.
Top mover ranking
There are no comparable price changes to rank in this publication. This edition is still archived under its publication date.
Segment summaries
Drug markets, manufacturers, and therapeutic classes aggregate the same NDC-level deltas. Average move is the mean percent change, while impact is the summed dollar-weighted effect using dispensing-volume exposure when the volume table is available.
Headline cards and archive stability
In editions with headline cards, most pressured class selects the largest positive class impact, and largest manufacturer swing selects the manufacturer with the largest aggregate absolute impact. Every weekly brief stores a frozen snapshot so archived pages do not drift when live NADAC data changes.

NADAC Week of Sep 23: Biosimilar Surge Drives Cost Pressure While Broader Market Skews Lower
The September 23, 2026 NADAC release compared against September 16 shows a market with more line-item decreases (15,294) than increases (13,311) across 29,892 comparable NDCs, indicating a mild net downward bias in pricing activity despite a few large upside outliers. The standout event is a $3.0M weighted increase in Fulphila (pegfilgrastim-jmdb) from Biocon Biologics, which single-handedly drove the Leukocyte Growth Factor class to the top of this week's cost-pressure rankings and made Biocon the largest manufacturer swing. On the relief side, Kesimpta (ofatumumab) posted the largest single-product decline at $469.9K, while the Corticosteroid class—spanning 1,122 drugs—registered a modest but broad-based $436.6K decrease, reinforcing that downward movement this week is more widely distributed than the upside, which is concentrated in a handful of specialty biologics.
