About Nevvi

Medicare utilization intelligence, built on public data. A product of TinyFlux Studio.

What Nevvi is

Nevvi answers a specific, practical question: for any Medicare procedure, in any state, which physician groups do the most of it — what they charge, how their volume has moved over the last twelve years, whether they're hospital-affiliated or independent, and how to reach them. It's free to search, with no signup, and deeper analysis available to subscribers.

Everything you see is drawn from data the U.S. government already publishes. Nevvi's job is to make it findable, comparable, and current — not to invent numbers on top of it.

How it's built

We ingest official CMS releases — the Medicare Physician & Other Practitioners file (Part B), the Doctors & Clinicians affiliation and roster files, and Medicare enrollment — and resolve them into a single provider-and-group graph. A plain-English search box translates a question ("who does the most heart valve replacements in Texas?") into the right CPT/HCPCS codes, and a twelve-year trend layer shows how each market has shifted. The full sourcing, coverage, and caveats live on our Methods & Sources page.

Independent by design

Nevvi is an independent product of TinyFlux Studio. It is not affiliated with, endorsed by, or sponsored by CMS or HHS. The underlying data is public and belongs to CMS; the compilation, the code-translation, the rankings, and the way it's presented here are ours. That independence is the point — we answer to the customer looking at the screen, not to any data vendor or health system.

Transparency

We show our work. Every figure traces back to a named CMS release with its vintage, and the limits of the data — Medicare fee-for-service only, small-count suppression, submitted charges rather than payments — are stated plainly rather than buried. If a number looks off, you should be able to see exactly where it came from. That's covered in detail under Methods & Sources.

Who it's for

Commercial, strategy, and investment teams in medical devices, diagnostics, and health services who need to know where procedure volume actually sits — and operators who'd rather not pay six figures for a database to find out.
