About T50.B93

T50.B93 is the ICD-10-CM diagnosis code for poisoning by other viral vaccines, assault. It belongs to category T50 (poisoning by, adverse effect of and underdosing of diuretics and other and unspecified drugs, medicaments and biological substances), 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 T50.B9, choose T50.B93 (Poisoning by other viral vaccines, assault) only when documentation doesn't support a more specific option: poisoning by other viral vaccines, accidental (unintentional) (T50.B91), poisoning by other viral vaccines, intentional self-harm (T50.B92), poisoning by other viral vaccines, undetermined (T50.B94), adverse effect of other viral vaccines (T50.B95) and underdosing of other viral vaccines (T50.B96).

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.
