T48 questions
What does T48 mean?
T48 is the ICD-10-CM code for Poisoning by, adverse effect of and underdosing of agents primarily acting on smooth and skeletal muscles and the respiratory system. It is in chapter 19, Injury, poisoning and certain other consequences of external causes (S00-T88).
Code titles come from the official ICD-10-CM files published by the CDC National Center for Health Statistics. Always check payer rules and the clinical record before billing.
