When a patient is hospitalized. On the discharge summary a provider will document primary and secondary Diagnosis? Do you only submit the dx's that were addressed during the hospital stay or all of them? I also have a provider that for observations discharge they list all active dx's , do we only report what the patient was being seen for? Any guidance would be great and if there is some "rule" written somewhere, I have been looking in my ICD 10 book and can not seem to find anything on it. Thanks in advance for anyone's help with this.
