T50.4X6Underdosing of drugs affecting uric acid metabolism

T50.4X6 is the ICD-10-CM diagnosis code for underdosing of drugs affecting uric acid metabolism. 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 T50.4X (poisoning by, adverse effect of and underdosing of drugs affecting uric acid metabolism), T50.4X6 is specifically for underdosing of drugs affecting uric acid metabolism. Related codes cover poisoning by drugs affecting uric acid metabolism, accidental (unintentional) (T50.4X1), poisoning by drugs affecting uric acid metabolism, intentional self-harm (T50.4X2), poisoning by drugs affecting uric acid metabolism, assault (T50.4X3), poisoning by drugs affecting uric acid metabolism, undetermined (T50.4X4) and adverse effect of drugs affecting uric acid metabolism (T50.4X5).

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.
