Every Medicare-enrolled physician by estimated age, specialty and place, with a rating for how likely their practice is to be independent of a hospital system. It's built from public CMS records for independent sponsors and roll-up groups.
One row, as it ships (name and address withheld)
Two things tell you whether a practice is a roll-up target: how old its physicians are, and whether a hospital system is already behind them. Each row answers both, so one filter gives you a list. These numbers are for the Springfield area.
Each market opens on the share of its physicians in each age band, with the U.S. dashed. If a market's curve sits above the nation's, more of its practices will change hands soon. This is Springfield, drawn from the same rows as the list.

Every physician within 25 miles of Springfield, placed on the map by practice location.
Physicians aged 60 and over, estimated from graduation year. Move the line to 50, 55, 65 or 70.
Aged 60 to 80, billing Medicare, and no tie to a hospital found in CMS records.
Billing groups of five or fewer: the solo and small practices a roll-up looks for.
Figures from the Springfield case study, data as of 2026-10-24.
For independent sponsors
Start from a specialty and a market, keep the physicians aged 60 and over with no hospital tie, and see who is in a solo or small group before you spend time on outreach.
For roll-up platforms
Count the older, independent practices around a platform's existing sites, so the next acquisition is chosen from a map of who is near retirement.
For lenders and advisors
Compare a market's physician age curve with the nation's: a market that sits above the curve has more practices that change hands in the next decade.
One row per physician. The independent practice rating comes from public records, and High means we found no hospital tie. Whether a physician plans to retire is a question for the call. Ages are estimates (they run young for international graduates), and the list only covers physicians enrolled in Medicare.
| Field group | What it holds |
|---|---|
| Physician | Name, NPI, specialty and credentials |
| Age | Estimated from medical school graduation year, with a state board's birth year where one is loaded |
| Practice | Street address, county, billing group name and the number of physicians billing under it |
| Activity | Medicare services and patients in the latest year, and whether they still bill |
| Independent practice (likelihood) | High, medium or low, with the reasons: hospital privileges, a hospital or system address, a billing group full of hospital-affiliated physicians |
| Evidence | The CMS files behind each field and their dates |
