The severity of esophagitis is commonly classified into four grades according to the Los Angeles Classification:[1][2]

Grade A One or more mucosal breaks < 5 mm in maximal length
Grade B One or more mucosal breaks > 5mm, but without continuity across mucosal folds
Grade C Mucosal breaks continuous between > 2 mucosal folds, but involving less than 75% of the esophageal circumference
Grade D Mucosal breaks involving more than 75% of esophageal circumference
