About T50.2X2
T50.2X2 is the ICD-10-CM diagnosis code for poisoning by carbonic-anhydrase inhibitors, benzothiadiazides and other diuretics, intentional self-harm. 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 T50.2X, choose T50.2X2 (Poisoning by carbonic-anhydrase inhibitors, benzothiadiazides and other diuretics, intentional self-harm) only when documentation doesn't support a more specific option: poisoning by carbonic-anhydrase inhibitors, benzothiadiazides and other diuretics, accidental (unintentional) (T50.2X1), poisoning by carbonic-anhydrase inhibitors, benzothiadiazides and other diuretics, assault (T50.2X3), poisoning by carbonic-anhydrase inhibitors, benzothiadiazides and other diuretics, undetermined (T50.2X4), adverse effect of carbonic-anhydrase inhibitors, benzothiadiazides and other diuretics (T50.2X5) and underdosing of carbonic-anhydrase inhibitors, benzothiadiazides and other diuretics (T50.2X6).
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.

The appropriate 7th character is to be added to each code from category T50
