About T46.6X5
T46.6X5 is the ICD-10-CM diagnosis code for adverse effect of antihyperlipidemic and antiarteriosclerotic drugs. 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 T46.6X (poisoning by, adverse effect of and underdosing of antihyperlipidemic and antiarteriosclerotic drugs), T46.6X5 is specifically for adverse effect of antihyperlipidemic and antiarteriosclerotic drugs. Related codes cover poisoning by antihyperlipidemic and antiarteriosclerotic drugs, accidental (unintentional) (T46.6X1), poisoning by antihyperlipidemic and antiarteriosclerotic drugs, intentional self-harm (T46.6X2), poisoning by antihyperlipidemic and antiarteriosclerotic drugs, assault (T46.6X3), poisoning by antihyperlipidemic and antiarteriosclerotic drugs, undetermined (T46.6X4) and underdosing of antihyperlipidemic and antiarteriosclerotic drugs (T46.6X6).
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.
