A clearer view of the market. Ready to share.

It shows how the national market has changed over time, estimates total Medicare scale beyond observed fee-for-service claims, and explains how much of that market is visible in public data.

With clear sources and assumptions, it gives strategy, commercial, and diligence teams a common reference for discussions and decisions.

How big is the market, and which way is it moving?

Whether this is a large, established market or a smaller one gaining momentum — and how fast it is changing.

Nevvi Market Brief

Market size and trajectory

Market volume and growth show the scale of current Medicare activity and the direction in which the market is moving. Together, they help distinguish large established markets from smaller markets gaining momentum.

Annual service volume is drawn from Medicare fee-for-service claims for the selected procedure code. Growth rates compare the latest available year with the prior year and the first year in the stated period. Estimated all-Medicare volume adjusts observed fee-for-service activity to account for Medicare Advantage enrollment and should be read as an estimate rather than directly observed claims volume.

How much of the market do the claims actually capture?

How much of real Medicare activity the fee-for-service claims capture, once Medicare Advantage is accounted for.

Observed and estimated market coverage

Comparing observed fee-for-service claims with estimated all-Medicare volume provides a more complete view of market scale. It also makes clear which values are directly observed and which are adjusted for broader Medicare enrollment.

Observed volume represents services recorded in Medicare fee-for-service claims. Estimated all-Medicare volume scales that activity using the fee-for-service share of Medicare enrollment in the relevant year and geography. The estimate assumes that utilization patterns are broadly the same across fee-for-service and Medicare Advantage populations, which may not hold in every market.

Who bills it, and how concentrated is supply?

The organizations behind the volume, and whether supply is fragmented or led by a few.

Billing groups and supply concentration

Billing-group analysis shows who supplies the service and how much volume sits with the largest organizations. It can help distinguish fragmented markets from those where a small number of groups hold most of the volume.

Named-group volume is aggregated from claims associated with clinicians linked to each billing group. Market shares and concentration measures use the volume that can be assigned at the organization level. Unassigned or unresolved claims may be excluded from named-group calculations, so group shares should not automatically be interpreted as shares of all market activity.

What the full Brief adds beyond a single-code lookup

The Market Brief shows not only how much activity exists, but whether the market is expanding and how much of it the public record still observes.
