This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

  • asphyxiation from carbon monoxide
  • toxic effect of carbon monoxide from all sources

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 T58
