Chronic kidney disease prevalence:
0.8–5.0% of adults
across 54 reporting states
(CDC BRFSS 2023–2024, age-adjusted state estimates).
Highest:
GU 5.0% · KY 4.6% · WV 4.6% · LA 4.4% · SC 4.4%
CDC-published US estimate: 3.9% (BRFSS 2024, crude prevalence — not age-adjusted, so not directly comparable to the state figures above).
CDC BRFSS prevalence is survey data covering all-payer adults 18 and older; Nevvi utilization counts Medicare fee-for-service only, largely 65 and older. The two appear side by side as context — Nevvi never combines them into a score, rating, or ranking. See Methods.
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 specialty" is the group's share of disclosed Medicare-FFS services for the primary code among groups with the SAME modal specialty in the state; "share of state" is the same figure against the whole state. Specialty is each group's modal member specialty from CMS's clinician register — a multi-specialty group carries one label. Where fewer than 11 groups share the specialty in the state, the specialty share renders "—" — the specialty benchmark is suppressed (fewer than 11 groups) and the state share alongside is the benchmark. Group figures sum clinicians affiliated with exactly one group. See Methods.
