T50.3X4Poisoning by electrolytic, caloric and water-balance agents, undetermined

T50.3X4 is the ICD-10-CM diagnosis code for poisoning by electrolytic, caloric and water-balance agents, undetermined. It belongs to category T50 (poisoning by, adverse effect of and underdosing of diuretics and other and unspecified drugs, medicaments and biological substances), 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 T50.3X (poisoning by, adverse effect of and underdosing of electrolytic, caloric and water-balance agents), T50.3X4 is specifically for poisoning by electrolytic, caloric and water-balance agents, undetermined. Related codes cover poisoning by electrolytic, caloric and water-balance agents, accidental (unintentional) (T50.3X1), poisoning by electrolytic, caloric and water-balance agents, intentional self-harm (T50.3X2), poisoning by electrolytic, caloric and water-balance agents, assault (T50.3X3), adverse effect of electrolytic, caloric and water-balance agents (T50.3X5) and underdosing of electrolytic, caloric and water-balance agents (T50.3X6).

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.
