Instructional Notations

7th Character Note 7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to each code from category T54

7th Character 7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela
