About T48.0
T48.0 is the ICD-10-CM diagnosis code for poisoning by, adverse effect of and underdosing of oxytocic drugs. It belongs to category T48 (poisoning by, adverse effect of and underdosing of agents primarily acting on smooth and skeletal muscles and the respiratory system), 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 1 subcodes must be used instead.
Within T48 (poisoning by, adverse effect of and underdosing of agents primarily acting on smooth and skeletal muscles and the respiratory system), T48.0 is specifically for poisoning by, adverse effect of and underdosing of oxytocic drugs. Related codes cover skeletal muscle relaxants [neuromuscular blocking agents] (T48.1), other and unspecified drugs acting on muscles (T48.2), antitussives (T48.3), expectorants (T48.4), other anti-common-cold drugs (T48.5), antiasthmatics, not elsewhere classified (T48.6) and other and unspecified agents primarily acting on the respiratory system (T48.9).
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.
Don't report T48.0 together with the conditions in its Excludes1 note: poisoning by, adverse effect of and underdosing of estrogens, progestogens and antagonists (T38.4-T38.6).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
