Section 10320 of the PPACA deals with the control of private health care costs and tasks some federal structure ( probably the Secretary of HHS) to takes action to decrease the growth of private health care cost.See here if you have not heard about 10320.
To control costs you might want data on costs, here is one mechanism by which the federal government could have access to that information. See here a discussion about a bill proposed in the Colorado legislature.It proposes mandatory data reporting and "harmonization" with federal data bases.
In the above link Linda Gorman says this:
"The Commonwealth Fund, AcademyHealth, and the Robert Wood Johnson Foundation are funneling money to efforts to convince state governments to pass laws requiring that all health care providers provide data to state run databases on every health care transaction. The goal is the creation of electronic records that can be used to track the type of medical care provided to each patient and the health behaviors of those judged to need oversight. These state efforts will be the building blocks for the ObamaCare electronic medical records system."
The bill talks about "all payer health claims", so I am assuming that this does not include the reporting by a private physician when she is paid by a patient outside of any insurance program. I hope that is correct. The bill is here for those who might want to figure out what exactly it is proposing.
Update on section 10320: As of 4/13/2010 a Google search for " section 10320" showed only my blog entries , those of DrRich of the Covert Rationing Blog,see here and this commentary.
