T39.2X6Underdosing of pyrazolone derivatives

T39.2X6 is the ICD-10-CM diagnosis code for underdosing of pyrazolone derivatives. 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 T39.2X (poisoning by, adverse effect of and underdosing of pyrazolone derivatives), T39.2X6 is specifically for underdosing of pyrazolone derivatives. Related codes cover poisoning by pyrazolone derivatives, accidental (unintentional) (T39.2X1), poisoning by pyrazolone derivatives, intentional self-harm (T39.2X2), poisoning by pyrazolone derivatives, assault (T39.2X3), poisoning by pyrazolone derivatives, undetermined (T39.2X4) and adverse effect of pyrazolone derivatives (T39.2X5).

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.
