About T47
T47 is the ICD-10-CM diagnosis code for poisoning by, adverse effect of and underdosing of agents primarily affecting the gastrointestinal system. It belongs to 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 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: T47.0 (blockers), T47.1 (drugs), T47.2 (laxatives), T47.3 (laxatives), T47.4 (laxatives), T47.5 (digestants), T47.6 (drugs), T47.7 (emetics) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
