Introduction The chest X-ray examination is an imaging modality that is widely used in screening for COVID-19 pneumonia. The problems with treating COVID-19 pneumonia patients are the high incidence and severity of the disease and the limitations of treatment room facilities. The chest X-ray Radiologic Severity Index is expected to assist clinicians in obtaining the relationship between the extent of lesions on X-ray and the duration of treatment and hospitalization for COVID-19 pneumonia patients. Results This study used an observational method using a retrospective approach. The research subjects were COVID-19 pneumonia patients from March 2020 to April 2021 who were hospitalized at Doctor Kariadi General Hospital Semarang. A total of 105 subjects confirmed positive RT-PCR and received serial X-ray examination services during treatment. The calculation of the RSI value was carried out on all X-ray chest X-rays and then statistically analyzed using the paired T test and Mann–Whitney methods. There was no significant relationship between the value of RSI1 and the duration of hospitalization with p  = 0.566, as well as the value of RSI2 with the duration of hospitalization with p  = 0.715. There is a significant relationship between the values of RSI1 and RSI2 with the use of the intensive care unit with p
