Provider Drill-Down

A curated set of high-profile outliers. (Full per-NPI lookup over all 7M providers is a live-warehouse feature; this static demo covers six headline cases.)

What these numbers mean (full math: Methodology):

Modified-z (drug cost): how far this provider sits from their (taxonomy × state) peer median, in robust (MAD) units; ≥ 3.5 is the flag threshold.
Brand cost share: the share of the provider's Part D drug cost that is brand-name rather than generic (0–1).
Peer group n: number of providers in the same taxonomy-and-state comparison set.

How extreme versus the peer group?

The selected provider's Part D drug cost against their (specialty × state) peer group, bucketed by cost band. Most peers cluster in the low bands; this provider sits alone in the far-right band — the extreme right-skew the MAD modified-z is designed to catch. (A plain linear histogram is unreadable here: ~all peers collapse into one bar near $0 while a lone outlier stretches the axis to tens of millions.)
