When a pt comes in for post op visit that is not fracture care or joint replacements, what is the best diagnosis code to use for correct coding purposes. I know that the visit is global and not billable but just looking for advice that if it was what would be the appropriate code to use. For ex. a post op from carpal tunnel, which dx code would be better suited? I've been instructed that if in global use V54.89, out of global use V67.09. Just curious!
