T39.95Adverse effect of unspecified nonopioid analgesic, antipyretic and antirheumatic

T39.95 is the ICD-10-CM diagnosis code for adverse effect of unspecified nonopioid analgesic, antipyretic and antirheumatic. 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 T39.9, choose T39.95 (Adverse effect of unspecified nonopioid analgesic, antipyretic and antirheumatic) only when documentation doesn't support a more specific option: poisoning by unspecified nonopioid analgesic, antipyretic and antirheumatic, accidental (unintentional) (T39.91), poisoning by unspecified nonopioid analgesic, antipyretic and antirheumatic, intentional self-harm (T39.92), poisoning by unspecified nonopioid analgesic, antipyretic and antirheumatic, assault (T39.93), poisoning by unspecified nonopioid analgesic, antipyretic and antirheumatic, undetermined (T39.94) and underdosing of unspecified nonopioid analgesic, antipyretic and antirheumatic (T39.96).

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.
