About T50
T50 is the ICD-10-CM diagnosis code for poisoning by, adverse effect of and underdosing of diuretics and other and unspecified drugs, medicaments and biological substances. 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 13 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: T50.0 (antagonists), T50.1 (diuretics), T50.2 (diuretics), T50.3 (agents), T50.4 (metabolism), T50.5 (depressants), T50.6 (agents), T50.7 (antagonists) and 5 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
