Code T48.0X6A captures the initial encounter for underdosing of oxytocic drugs, such as pitocin or oxytocin used during labor. Underdosing in ICD-10-CM means a patient took or was administered less of a drug than was prescribed or medically indicated. Proper coding requires dual sequencing: the clinical condition resulting from the underdosing is reported first, followed by the underdosing code itself. Documenting patient non-compliance versus accidental under-administration is key for correct secondary coding.
