Excellent piece. Some evidence ACOs do better  https://www.ncbi.nlm.nih.gov/pubmed/26390323 . Changing incentives helps, but not sufficient for big effects  https://twitter.com/jnmafi/status/952555042317459456 
Just to reiterate, I am no longer on medpac and was not at meeting. My sense is they mean something close to variable contribution margin. But I think the point of their term is the profits from Medicare if we assumed Medicare is the marginal payer.  https://twitter.com/radrandd/status/952320483927576576 
I think it's a semantic thing. I defer to @DavidCGrabowski. Apart from the theory vs actual issue, there are accounting issues about how reasonable returns are counted and where fixed costs. And I wouldn't apply perfectly competitve instincts to what to expect  https://twitter.com/radrandd/status/952279704899223552 
Yes, but the first tweet mentioned aggregate profit I think. Probably meant aggregate Medicare margin, but I wanted to be explicit about the difference between total margin and total Medicare margin.  https://twitter.com/radrandd/status/952273511053115392 
@DavidCGrabowski will be able to correct me, but the marginal margin I think excludes fixed costs. Total margins are always better than Medicare margins because commercial payers pay more  https://twitter.com/afrakt/status/952241736004366337
