T48.5X1Poisoning by other anti-common-cold drugs, accidental (unintentional)

T48.5X1 is the ICD-10-CM diagnosis code for poisoning by other anti-common-cold drugs, accidental (unintentional). It belongs to category T48 (poisoning by, adverse effect of and underdosing of agents primarily acting on smooth and skeletal muscles and the respiratory 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 T48.5X, choose T48.5X1 (Poisoning by other anti-common-cold drugs, accidental (unintentional)) only when documentation doesn't support a more specific option: poisoning by other anti-common-cold drugs, intentional self-harm (T48.5X2), poisoning by other anti-common-cold drugs, assault (T48.5X3), poisoning by other anti-common-cold drugs, undetermined (T48.5X4), adverse effect of other anti-common-cold drugs (T48.5X5) and underdosing of other anti-common-cold drugs (T48.5X6).

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.
