T49.0X6Underdosing of local antifungal, anti-infective and anti-inflammatory drugs

T49.0X6 is the ICD-10-CM diagnosis code for underdosing of local antifungal, anti-infective and anti-inflammatory drugs. It belongs to category T49 (poisoning by, adverse effect of and underdosing of topical agents primarily affecting skin and mucous membrane and by ophthalmological, otorhinorlaryngological and dental drugs), 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 T49.0X (poisoning by, adverse effect of and underdosing of local antifungal, anti-infective and anti-inflammatory drugs), T49.0X6 is specifically for underdosing of local antifungal, anti-infective and anti-inflammatory drugs. Related codes cover poisoning by local antifungal, anti-infective and anti-inflammatory drugs, accidental (unintentional) (T49.0X1), poisoning by local antifungal, anti-infective and anti-inflammatory drugs, intentional self-harm (T49.0X2), poisoning by local antifungal, anti-infective and anti-inflammatory drugs, assault (T49.0X3), poisoning by local antifungal, anti-infective and anti-inflammatory drugs, undetermined (T49.0X4) and adverse effect of local antifungal, anti-infective and anti-inflammatory drugs (T49.0X5).

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.
