We hear about big payors like Optum buying up primary care practices - but how big is that, really?
See remarks at Linked In by Brian Miller - here - and see a new paper in Health Affairs Scholar by Adler et al. here.
Here's Brian's summary:
Ironically this paper shows that Optum is not a competitive concern in primary care markets:
-Payers own 4% and Optum owns 2.71% of all primary care practices
-Optum max market share 35% in 3 counties
-There are over 3,200 counties
