Likewise the average cost of an angioplasty in the US is $28,182 while it is $14,366 in the next most expensive country, the United Kingdom of Great Britain. At the 25th percentile in the US the cost is $16,533 which is close to Great Britain. The upper end of the scale cost (95th percentile) is $61,649. This is four times the cost of Great Britain.
