CMS makes it clear that a visit is not billable on same DOS as a minor procedure unless it is "significant, separately identifiable." They clearly state the rule as applying only to visits on the same day. Does anybody know if this rule applies to visits on the previous DOS? We have a group for whom it is not unusual to perform a visit late one evening and then perform the minor procedure early the following morning. Ethically, I'm of the opinion that we should follow CMS guidelines for same DOS, but I want something concrete to show our docs.
