I work for a family practice and we had a patient that was seen for an er follow up visit due to a work related injury, apparently the patient did not inform us that the injury was work related at the time of service. So the provider treated him for the injury and ordered an X-ray, but the provider also restarted the patient on some previous meds not related to the work injury, the patient was referred to cardiology and had some medications refilled. The DX codes that were used are: S60.450A9This is the work related injury, I10, I70.0 and E78.2. My question is, can I still submit this claim to workers comp with all of these DX codes? and if there is no workers comp claim do I then bill the Patient?
