    When performing diagnostic and interventional radiology coding audits, is there an accepted industry standard for statistically valid sample sizes of total accessions reviewed?

    John – Others may have a different response but for me it is about establishing the confidence of the accuracy of the audit. You can establish a 60% confidence that the audit is statistically significant up to 99% confidence. I usually shoot for 80%. Once that confidence level has been set it's a simple calculation knowing the "n" or number of charts there are to audited and then pulling up a "t" Table and calculate the numbers of charts to audit to hit the confidence level you wish to achieve.  Granted I was a bit more picky when I was doing audits because I wanted to be able to make a statement that that I was XX% confident that the dictations met compliance requirements for coding, etc. The Radiologists always seems very appreciative of that effort and when you included the t-tail calculations in the report they knew exactly what was done and why.... Hope that helps.....

    John, I've attached a sample size calculator that we use when performing random sample audits.  

    This is also a helpful online link with calculator.

    Hope this is helpful.
