Principal conditions are based on the first-listed diagnosis on the ED visit record and are classified using AHRQ's Clinical Classifications Software (CCS). General CCS “other” conditions are not reported in the table and include the following conditions by age group: other upper respiratory infections (<1 year: 540,700 ED visits; 1–17 years: 2,550,600 ED visits; 18–44: 1,926,500 ED visits); other perinatal conditions (<1 year: 151,400 ED visits); other injuries and conditions due to external causes (1–17 years: 1,075,500 ED visits; 85+ years: 126,200 ED visits). “Other” CCS categories include miscellaneous, otherwise unclassifiable diagnoses that may be difficult to interpret as a group.
