About T45.601

T45.601 is the ICD-10-CM diagnosis code for poisoning by unspecified fibrinolysis-affecting drugs, accidental (unintentional). It belongs to category T45 (poisoning by, adverse effect of and underdosing of primarily systemic and hematological agents, not elsewhere classified), 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 T45.60, choose T45.601 (Poisoning by unspecified fibrinolysis-affecting drugs, accidental (unintentional)) only when documentation doesn't support a more specific option: poisoning by unspecified fibrinolysis-affecting drugs, intentional self-harm (T45.602), poisoning by unspecified fibrinolysis-affecting drugs, assault (T45.603), poisoning by unspecified fibrinolysis-affecting drugs, undetermined (T45.604), adverse effect of unspecified fibrinolysis-affecting drugs (T45.605) and underdosing of unspecified fibrinolysis-affecting drugs (T45.606).

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.
