About T47.6X6
T47.6X6 is the ICD-10-CM diagnosis code for underdosing of antidiarrheal drugs. 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 T47.6X (poisoning by, adverse effect of and underdosing of antidiarrheal drugs), T47.6X6 is specifically for underdosing of antidiarrheal drugs. Related codes cover poisoning by antidiarrheal drugs, accidental (unintentional) (T47.6X1), poisoning by antidiarrheal drugs, intentional self-harm (T47.6X2), poisoning by antidiarrheal drugs, assault (T47.6X3), poisoning by antidiarrheal drugs, undetermined (T47.6X4) and adverse effect of antidiarrheal drugs (T47.6X5).
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.
