CMS change of ownership (CHOW) data
WhoOwnsCare holds 2,396 Medicare change-of-ownership records across California, Texas, Florida, Ohio, Illinois, Pennsylvania and New York, each naming the acquiring and prior parties and the effective date.
A CHOW is a regulatory event, not a deal announcement. It carries no price, no terms, and no indication of whether the transfer was a sale or an internal reorganisation.
Fields and their behaviour
Each record carries the provider, the acquiring party, the prior party, an effective date and a transaction type. The prior party is identified by an enrolment identifier that has since been retired, which is why attribution has to be done by identity rather than by join.
Sale versus restructuring
A group moving buildings between entities it already controls files the same form as an outside buyer. Attributing both sides to a resolved corporate family separates them: when the acquiring and prior families are the same, the transfer is internal. That is what makes the acquisition view meaningful rather than a filing count.
Reporting lag
CMS publishes these with a lag. Recent quarters are always incomplete and should never be read as a slowdown in transaction activity.
Common questions
What is a CHOW?
A change of ownership: the filing made when a Medicare provider's ownership transfers to a different party.
Does a CHOW record the sale price?
No. Price and terms are not in the public record.
