Every Medicare procedure market — size, growth, structure, and who runs it.
What kind of market this is, from Medicare's own numbers.
The platform is where the analysis happens: total a market's Medicare volumes and payments, and trace who controls it down to every clinician.
What a subscription adds
Explore
Who each group and clinician is, and what the market charges and is paid, with five years of every market's history.
Analyze
Compare sets two to six of one kind side by side: groups, clinicians, codes, hospitals, MS-DRGs, medications, or state markets. Atlas reads one market back to you: its size, who bills it, and what changed. Analyze also adds the Burden overlay, the What-if simulator, and the Clinician network.
Deep Dives
A Deep Dive opens the rest of one group, clinician, code, MS-DRG, hospital, or medication page and keeps a dated record in your Saved. For a group, clinician, or code, Nevvi analyzes it too. A group's Deep Dive also keeps what stands out and unveils its Group Brief. Explore and Analyze include a yearly allowance; All Access removes the meter.
What is open to read, and what a subscription computes
12-year market trendlines
Twelve years of market-level Medicare utilization behind every code: adoption curves, growth, and charge trajectories.
Atlas
Name a market (a set of codes, the nation or one state, a year) and Atlas reads it back: how large it is, who bills it, what changed since the year before, and where it sits among the state markets.
Browse by category
Find a market without knowing its code: procedures by clinical category and family, inpatient stays by body system and DRG, and Part D medications.
Burden overlay
Disease burden beside billed volume, by state. Pick a condition and Nevvi starts with the codes its signed map links to it; take any out and add any code you like. Burden and each code stay separate measures on separate scales.
Clinician network
Start from one clinician or one medical group: Nevvi counts the clinicians who billed Medicare through the same organization, in the same specialty, in overlapping years, from the CMS rosters of 2019 on. A shared roster is a billing record, not evidence that two people met. A Deep Dive on the clinician or group names the clinicians behind the counts, with the organization and the years.
Clinicians in the market
Every individual clinician billing the code, ranked on their own — city, specialty, and volumes, separate from the groups they bill under.
Co-billed codes
The codes the same organizations bill alongside a code, ranked by how much the two codes' billing groups overlap — with the counts behind every pair. Practice scope and equipment, not clinical sequence.
Codes that pay similarly
The codes inside a band of one code's Medicare rate — the list is open to everyone; the platform adds each code's rate, and what the groups billing it charge, what they are paid, and the ratio between those two where the record shows it.
Compare
Two to six of one kind side by side: groups, clinicians, codes, hospitals, MS-DRGs, medications, or state markets.
Deep Dives
A Deep Dive opens the rest of one group, clinician, code, MS-DRG, hospital, or medication page and keeps a dated record in your Saved. For a group, clinician, or code, Nevvi analyzes it too. A group's Deep Dive also keeps what stands out and unveils its Group Brief. Explore and Analyze include a yearly allowance; All Access removes the meter.
Disease-burden context
CDC burden overlays on market views, where available — surface states where procedure volume hasn't caught up to the disease. State-grain, methodology disclosed.
Emerging procedures & adopters
Newly-introduced procedures as they diffuse — grouped by clinical family — and the physicians who billed each one earliest. Adoption cohorts and diffusion for any emerging market.
Export what you search
The ranked group table you search downloads to CSV at full depth: every row, phones and affiliations. One market at a time, for your own work — the whole dataset is a separate license. Included with All Access, and on Explore and Analyze for a code your account has Deep Dived.
Five-year data history
Open any market in any of the last five years, not just the two most recent — every year the same exact Medicare volumes, so you can read a market's trajectory year by year.
Inpatient markets
Medicare inpatient stays by MS-DRG — discharge volumes and how they rank across hospitals and geographies, alongside the outpatient markets.
Market position
Where this market sits on volume and growth among all state markets, and its rank.
Market structure & concentration
Top-5 share and its concentration band, independent vs hospital-affiliated split, and the consolidation trend — for any procedure market.
Market structure, to the clinician
Open any group to every clinician on it — NPIs, credentials, per-code volumes and charges. See how concentrated a market really is.
Market trend at a glance
Every market view carries its year-over-year direction — volume growth or decline, framed against the state's enrollment change.
Medicare Part D drug markets
Any Part D medication, nationwide or by state. The size of its market is open to read: its claims, their growth, and its largest state markets. Explore opens its Overview and what Medicare Part D spends on it. A Deep Dive opens where it is prescribed state by state, who prescribes it by name, and its brands and generics.
National benchmarks
Where each group's volume sits nationally and within its specialty.
Non-billers
Groups built like a code's billers, in the same market, with no published volume on it in the public record — in the seed's specialty or the neighbouring ones. The per-state counts are open to everyone; the platform names the groups.
Payer-mix visibility
Every market number carries its payer-mix frame — how much of Medicare in the state is fee-for-service, and how far Medicare Advantage has grown. Scale a market to an all-Medicare estimate, labeled as an estimate, never an observed count.
Plain-English search
Describe the market in your own words — Nevvi translates it to the right codes and runs the same ranked search.
Practice economics
What Medicare paid a medical group in a year, how many clinicians, codes and services that covers, and how many states it bills in — and, code by code, what the group and each of its clinicians charge and are paid.
Practices built like a group
The practices built like a group — similar clinician count, service volume, and Medicare payment, in the same market.
Provider & group profiles
Look up any clinician or group by name or NPI — profile pages with specialties, locations, and the codes they bill.
Single-code market search
Any CPT®/HCPCS code, any state — the ranked groups: rank, city, specialty, size, and volumes, with hospital affiliations on every row. No signup.
Specialty markets
Which specialties bill Medicare the most, and where: each specialty's Medicare billing, state by state.
Specialty view
Rank the same market within a specialty — compare like with like, with specialty-market share where the market is deep enough.
State markets
Every state's Medicare billing on one page: the services physician groups billed there, what Medicare paid, and the state's share of the national total.
The full ranked list
The ranked tables open at the top 25 groups and the top 25 clinicians for everyone, ranked with their volumes. The platform names who each ranked row is — and opens the rest of the ranking, every group and every clinician in the market, in order.
The record behind a name
What the registry holds on a group or clinician — which hospitals and facilities they are affiliated with, how long they have been in practice, the scale of the group they bill under, and how their affiliations have moved since 2019.
What a clinician prescribes
A named clinician's Part D prescribing beside the procedures they bill — drugs, volumes, and the cardio-kidney-metabolic classes they fall in.
What the market charges and is paid
The market's average charge and average payment — and the same pair for every group and clinician in the ranking, beside their volumes.
What-if simulator
Two questions about one practice's Medicare record: where its prices sit against its market, and what a related service its peers bill could come to. Both are arithmetic on the record, stated as conditions, never advice. The market for any code, and each related service's share, pattern, and rate, are open for any practice. The practice's own figures fill in with a Deep Dive on it.
Where a code is billed
Every state where a code has published volume, ranked — and a year-by-year grid of where it has been billed, shaded on the rate per 1,000 fee-for-service beneficiaries. Entering or leaving the table is an observation against CMS's disclosure floor, never a first-use or a stop-use claim.
Who the hospital is, and what it is paid
The hospital behind each ranked inpatient row — its name and CCN, what its stays are charged and paid, and its whole DRG portfolio.
Every market's overview — its size, its structure, and where it sits against every other state market — is open to read. Explore opens every page's Overview, including what the market charges and is paid. Analyze adds Compare, Atlas, the Burden overlay, the What-if simulator, and the Clinician network. A Deep Dive opens the rest of one group, clinician, code, MS-DRG, hospital, or medication page, including the names of the groups, clinicians, and hospitals it lists, and keeps a dated record in your Saved. For a group, clinician, or code, Nevvi analyzes it too. A group's Deep Dive also keeps what stands out.
