Suspected and confirmed COVID-19, though not an ICD-10 chapter, is included in this table to demonstrate the contribution of these problem list terms to overall estimates of problem list completion. Some patients had more than one COVID-19 problem list entry, e.g. a general COVID-19 term and a term for a complication of COVID-19, hence the total number of entries (627) is greater than the number of patients in the study (516).
