T39.311Poisoning by propionic acid derivatives, accidental (unintentional)

T39.311 is the ICD-10-CM diagnosis code for poisoning by propionic acid derivatives, accidental (unintentional). It belongs to category T39 (poisoning by, adverse effect of and underdosing of nonopioid analgesics, antipyretics and antirheumatics), 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 T39.31 (poisoning by, adverse effect of and underdosing of propionic acid derivatives), T39.311 is specifically for poisoning by propionic acid derivatives, accidental (unintentional). Related codes cover poisoning by propionic acid derivatives, intentional self-harm (T39.312), poisoning by propionic acid derivatives, assault (T39.313), poisoning by propionic acid derivatives, undetermined (T39.314), adverse effect of propionic acid derivatives (T39.315) and underdosing of propionic acid derivatives (T39.316).

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.
