I have seen documentation for nurse only visits where a patient is seen for a sick visit by the Registered Nurse only. The nurse takes vitals, does brief exam, may do rapid strep and/or rapid influenza if appropriate. The nurse then "concurs" with the physician or nurse practitioner who may issue prescription for meds if appropriate; if no prescription issued directive to continue with home care, increased fluids and rest, etc. to patient. I have coded these visits as Non-billable encounters since the physician did not order the services and Incident To requirements have not been met and claims have been adjusted off. However; there are those in clinic that feel these visits should be billable because the Nurse concurred with the provider. There is no separate documentation from the physician/NP. Can someone point me in the direction of where I can find that "Sick" visits by a nurse only do not constitute Incident To service to back me up??? Any help would be appreciated.
