Question

Quizplus · Accepted Answer

The seventh character is used in certain ICD-10-CM categories to provide more specificity about the condition being coded. This character is typically a letter or number that indicates information such as the episode of care or the type of encounter. It is not referred to as the alpha extension or subsequent digit. The term "specificity classification" is not typically used in relation to the seventh character.
