T44.8X6Underdosing of centrally-acting and adrenergic-neuron-blocking agents

T44.8X6 is the ICD-10-CM diagnosis code for underdosing of centrally-acting and adrenergic-neuron-blocking agents. It belongs to category T44 (poisoning by, adverse effect of and underdosing of drugs primarily affecting the autonomic nervous 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 T44.8X (poisoning by, adverse effect of and underdosing of centrally-acting and adrenergic- neuron-blocking agents), T44.8X6 is specifically for underdosing of centrally-acting and adrenergic-neuron-blocking agents. Related codes cover poisoning by centrally-acting and adrenergic-neuron-blocking agents, accidental (unintentional) (T44.8X1), poisoning by centrally-acting and adrenergic-neuron-blocking agents, intentional self-harm (T44.8X2), poisoning by centrally-acting and adrenergic-neuron-blocking agents, assault (T44.8X3), poisoning by centrally-acting and adrenergic-neuron-blocking agents, undetermined (T44.8X4) and adverse effect of centrally-acting and adrenergic-neuron-blocking agents (T44.8X5).

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.
