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 T55

About the T55 Code Range
Soaps and detergents can have toxic effects. These substances belong to the group chiefly nonmedicinal in source.
T55.0 identifies soap, while T55.1 identifies detergent. Each branch separates accidental effects, intentional self-harm, assault, and undetermined intent. The final character distinguishes an initial encounter (A), a subsequent encounter (D), or a sequela (S), meaning a later effect.
