About T41.0X6
T41.0X6 is the ICD-10-CM diagnosis code for underdosing of inhaled anesthetics. It belongs to category T41 (poisoning by, adverse effect of and underdosing of anesthetics and therapeutic gases), 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 T41.0X (poisoning by, adverse effect of and underdosing of inhaled anesthetics), T41.0X6 is specifically for underdosing of inhaled anesthetics. Related codes cover poisoning by inhaled anesthetics, accidental (unintentional) (T41.0X1), poisoning by inhaled anesthetics, intentional self-harm (T41.0X2), poisoning by inhaled anesthetics, assault (T41.0X3), poisoning by inhaled anesthetics, undetermined (T41.0X4) and adverse effect of inhaled anesthetics (T41.0X5).
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.
