About T39.8X5
T39.8X5 is the ICD-10-CM diagnosis code for adverse effect of other nonopioid analgesics and antipyretics, not elsewhere classified. 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 T39.8X, choose T39.8X5 (Adverse effect of other nonopioid analgesics and antipyretics, not elsewhere classified) only when documentation doesn't support a more specific option: poisoning by other nonopioid analgesics and antipyretics, not elsewhere classified, accidental (unintentional) (T39.8X1), poisoning by other nonopioid analgesics and antipyretics, not elsewhere classified, intentional self-harm (T39.8X2), poisoning by other nonopioid analgesics and antipyretics, not elsewhere classified, assault (T39.8X3), poisoning by other nonopioid analgesics and antipyretics, not elsewhere classified, undetermined (T39.8X4) and underdosing of other nonopioid analgesics and antipyretics, not elsewhere classified (T39.8X6).
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.
