About T48.1X2
T48.1X2 is the ICD-10-CM diagnosis code for poisoning by skeletal muscle relaxants [neuromuscular blocking agents], intentional self-harm. It belongs to category T48 (poisoning by, adverse effect of and underdosing of agents primarily acting on smooth and skeletal muscles and the respiratory system), 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 T48.1X (poisoning by, adverse effect of and underdosing of skeletal muscle relaxants [neuromuscular blocking agents]), T48.1X2 is specifically for poisoning by skeletal muscle relaxants [neuromuscular blocking agents], intentional self-harm. Related codes cover poisoning by skeletal muscle relaxants [neuromuscular blocking agents], accidental (unintentional) (T48.1X1), poisoning by skeletal muscle relaxants [neuromuscular blocking agents], assault (T48.1X3), poisoning by skeletal muscle relaxants [neuromuscular blocking agents], undetermined (T48.1X4), adverse effect of skeletal muscle relaxants [neuromuscular blocking agents] (T48.1X5) and underdosing of skeletal muscle relaxants [neuromuscular blocking agents] (T48.1X6).
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.
