About T39.0
T39.0 is the ICD-10-CM diagnosis code for poisoning by, adverse effect of and underdosing of salicylates. 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 2 subcodes must be used instead.
Within T39 (poisoning by, adverse effect of and underdosing of nonopioid analgesics, antipyretics and antirheumatics), T39.0 is specifically for poisoning by, adverse effect of and underdosing of salicylates. Related codes cover 4-Aminophenol derivatives (T39.1), pyrazolone derivatives (T39.2), other nonsteroidal anti-inflammatory drugs [NSAID] (T39.3), antirheumatics, not elsewhere classified (T39.4), other nonopioid analgesics and antipyretics, not elsewhere classified (T39.8) and unspecified nonopioid analgesic, antipyretic and antirheumatic (T39.9).
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.
