T46.8X6Underdosing of antivaricose drugs, including sclerosing agents

T46.8X6 is the ICD-10-CM diagnosis code for underdosing of antivaricose drugs, including sclerosing agents. 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), T46.8X6 is specifically for underdosing of antivaricose drugs, including sclerosing agents. 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), poisoning by antivaricose drugs, including sclerosing agents, undetermined (T46.8X4) and adverse effect of antivaricose drugs, including sclerosing agents (T46.8X5).

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.
