About T47.8X5
T47.8X5 is the ICD-10-CM diagnosis code for adverse effect of other agents primarily affecting gastrointestinal system. It belongs to category T47 (poisoning by, adverse effect of and underdosing of agents primarily affecting the gastrointestinal system), block T36-T50 (poisoning by, adverse effects of and underdosing of drugs, medicaments and biological substances) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
Within T47.8X, choose T47.8X5 (Adverse effect of other agents primarily affecting gastrointestinal system) only when documentation doesn't support a more specific option: poisoning by other agents primarily affecting gastrointestinal system, accidental (unintentional) (T47.8X1), poisoning by other agents primarily affecting gastrointestinal system, intentional self-harm (T47.8X2), poisoning by other agents primarily affecting gastrointestinal system, assault (T47.8X3), poisoning by other agents primarily affecting gastrointestinal system, undetermined (T47.8X4) and underdosing of other agents primarily affecting gastrointestinal system (T47.8X6).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

The appropriate 7th character is to be added to each code from category T47
