About T49.1X6
T49.1X6 is the ICD-10-CM diagnosis code for underdosing of antipruritics. It belongs to category T49 (poisoning by, adverse effect of and underdosing of topical agents primarily affecting skin and mucous membrane and by ophthalmological, otorhinorlaryngological and dental drugs), 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 T49.1X (poisoning by, adverse effect of and underdosing of antipruritics), T49.1X6 is specifically for underdosing of antipruritics.
