My guess is the the billers are getting edits in the system and/or denials from the insurance companies.
I actually think it's a good idea to look at claims before they go out and compare them to the CCI, LCDs, NCDs, etc. As long as the billers aren't just picking any old code to get the claim paid, then it's not fraud.. but this may be something you can address with your compliance department. There should definitely be something in writing about this process.
At my last job, I had all the coders review everything (e.g. for Medicare pts review for any LCDs). If we knew the claim would deny for the dx, we would query the physician and/or request medical records to see if there was 'something better'.
Here's an example... some of the skin excision codes had LCDs; often times, the docs would just write 'lesion' on the charge ticket, which was not a covered diagnoses. We would then see if it was actually a neoplasm or some other specific dx. If so, we'd change to appropriate dx, and if not, we'd submit the claim w/ a -GZ mod. This saved time in the long run for the people working denials.
I hope that makes sense!
