Really, like Tameka says, it is the provider/coder's job to code to the highest level of specificity. The reference they should be using is the ICD-10 manual, which has every code in it, if they don't have an EMR where every code is already uploaded. If you have to spend time going through each claim, trying to figure out if they could have used a more specific code, you will be there all day.
It has been almost a year since ICD-10 took effect, and if providers.coders are still using unspecified codes, when a more specific one is available, I look at that like they just don't care if their claims start to deny come Oct. 1, 2016. They were given a grace period, that they should be thankful they even got...at this point, they need to step up and code correctly.
