When documentation confirms systemic antibiotic poisoning but cannot establish whether the intent was accidental, self-harm, or assault, T36.8X4 steps in. Category T36 covers systemic antibiotics, and the fourth character subclassification .8 identifies specified antibiotics other than penicillins, cephalosporins, macrolides, tetracyclines, or aminoglycosides. The 5th character X acts as the placeholder, while the 6th character 4 denotes an undetermined intent. Remember to assign a mandatory 7th character for encounter type to complete this 7-character code. Always query the clinical record thoroughly before settling on an undetermined intent digit.
