Market analyticsPlatform

a taste of the twelve-year trend layer

Market position — where this market sits on volume and growth among all state markets, and its rank.
Worth a look — every state market for this search, ranked by a published score: size, growth, fragmentation, below-expected volume.
Lookalike opportunities — groups billing below what peers of the same specialty, size, and state predict, with the expected figure shown.
National benchmarks — where each group's volume sits nationally and within its specialty.
Market structure — how concentrated this market is, and who owns the volume.
Medicare-wide scaling — the exact payer split, and this market total scaled to all of Medicare, labeled as an estimate.

Nevvi's market analytics platform — code baskets, market structure and share, the twelve-year trend layer — is built and not launched yet. We're gathering interest in it.

*Share of the state's disclosed Medicare-FFS services for the primary code, counted once per clinician. "St" is the state the volume was billed from: a group appears in each state where its clinicians bill Medicare, with that state's volume and share ("City" is the group's registered location). Group figures sum clinicians affiliated with exactly one group; clinicians in several groups are listed in each group's drill-down but not volume-attributed to any single group, so shares reflect attributable volume. See Methods.

Comparing against an all-payer estimate?

These are exact counts from Medicare fee-for-service claims — roughly a third to half of most procedure markets, depending on payer mix. Modeled all-payer databases project the remainder statistically; we publish the audited floor and label it as such. Same market, different denominator. How the numbers reconcile →
