T46.8X4Poisoning by antivaricose drugs, including sclerosing agents, undetermined

T46.8X4 is the ICD-10-CM diagnosis code for poisoning by antivaricose drugs, including sclerosing agents, undetermined. It belongs to category T46 (poisoning by, adverse effect of and underdosing of agents primarily affecting the cardiovascular 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 T46.8X (poisoning by, adverse effect of and underdosing of antivaricose drugs, including sclerosing agents), T46.8X4 is specifically for poisoning by antivaricose drugs, including sclerosing agents, undetermined. Related codes cover poisoning by antivaricose drugs, including sclerosing agents, accidental (unintentional) (T46.8X1), poisoning by antivaricose drugs, including sclerosing agents, intentional self-harm (T46.8X2), poisoning by antivaricose drugs, including sclerosing agents, assault (T46.8X3), adverse effect of antivaricose drugs, including sclerosing agents (T46.8X5) and underdosing of antivaricose drugs, including sclerosing agents (T46.8X6).

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.
