Medicare isn't spending much on primary care

Primary care only accounted for between 2.1% and 4.9% of total Medicare spending in 2015, depending on how primary care is defined, according to a new RAND study published in JAMA Internal Medicine.

Why it matters: Primary care is a lot cheaper than, say, surgery for a condition that has gotten worse while untreated. We may not know the magic percentage of spending that should go toward primary care, but it's a good thing to consider when we talk about lowering costs.
