100 per hour, if op reports, seems unreasonable. my staff doesn't have to meet any productivity measures at this point. they code what they can - as fast as they can - but with accuracy. depending on the complexity of the surgery, on average, i'd say about 40 cases an hour - and that might be stretching it. could be sometimes more, sometimes less. and with those 40 cases, the op report is completely stripped of all billable components and both the icd9's and cpt's are defined and of course appending modifiers. tools such the cci edits, lcd's, ncd's are used, which takes time - much more time than 100 per hour- there's just no way. the coders do not bill these cases, they are sent on to the 'billers'.
some cases take 2 seconds, if it's say - an open appendectomy and just that - or maybe a simple hernia repair. you might be able to code 100 of those cases in an hour.
