Implementation of ICD-10s has been delayed “indefinitely.” Rather than opine on whether that’s a good thing or a bad thing, I will note that it creates an opportunity for a simple but powerful improvement in the value of the coding.
Caveat: I am not a coding expert (I don’t even play one on TV) so there might be something wrong with this idea. The specific reason for the post is to find out whether there is some reason this can’t be done, given the value of doing it. (I am so unfamiliar with coding that it is possible this is already being done and I’m the last guy to find out about it, in which case perhaps John and Matthew would be kind enough to remove it.)
Quite simply, how about adding an optional “R” for “rule-out” after the codes? For instance, today if a patient gets tested for diabetes and it turns out that he HAS diabetes, he gets coded “250” in the ICD-9s. Whereas if it turns out the patient does NOT have diabetes, he still gets coded “250.” My proposal would code that (in ICD-9s) 250R.
By contrast, giving two opposite diagnoses the same code creates a cascading set of problems, in outcomes measurement, risk scoring, registries, disease management, reimbursement, and predictive modeling, problems that will be exacerbated as risk shifts down to the provider level and payors move to outcomes-based reimbursement.
