Final answer:
Uncertain diagnoses are reported in inpatient settings but not in outpatient settings. These diagnoses differ from nosocomial and iatrogenic diseases, as they are provisional and pending confirmation.
Step-by-step explanation:
In an inpatient setting, uncertain diagnoses are reported, but in the outpatient setting these uncertain diagnoses are not reported. Unlike nosocomial diseases, which are contracted in hospital settings, or iatrogenic diseases, which are directly caused by medical procedures, uncertain diagnoses refer to medical conditions that a physician suspects, but has not yet confirmed through further testing or observation. It is standard practice to include these provisional or differential diagnoses in the patient's medical record within an inpatient (e.g., hospital) setting to ensure comprehensive care and monitoring. However, in the outpatient setting, which encompasses medical care provided outside the hospital such as in clinics or physician offices, coding and billing practices dictate that only confirmed diagnoses should be reported.
