We have this big dilemma over Urgent Care claims (CMS 1500). It comes up in other specialties as well. We have some Urgent Care groups stating they don't need to submit a rendering provider and can leave box 24 J blank. We have some that are putting a rendering physician on the claims but are set up not to allow this as their contract requires it. Are there any requirements either way? Personal preference? Organization type? We have a few hundred claims stuck in pend status due to the debate and probably just as many denials.
