About T49.3X4
T49.3X4 is the ICD-10-CM diagnosis code for poisoning by emollients, demulcents and protectants, undetermined. 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).
