Difference between Medicare and Medicaid reporting levels a
High	≤10%
Medium	10% < x ≤ 20%
Low	20% < x ≤ 50%
Very low	>50%

Note: ** is placed in cells that contained too few claims to meet the minimum cell size requirements of our data use agreement with the Centers for Medicare and Medicaid Services. INC's are placed in cells that reported a mileage of 0 or blank for all ambulance claims.

Abbreviations: MAX FFS, Medicaid Analytic eXtract fee‐for‐service; MAX MC, Medicaid Analytic eXtract managed care; MCARE FFS, Medicare fee‐for‐service; e‐code, external cause of injury code.

^a The data quality was indicated as high, medium, low, or very low if the percentage point difference with Medicare falls within the interval. We compared the same years (2011–2014) between MAX and Medicare.
