T38.1X3Poisoning by thyroid hormones and substitutes, assault

T38.1X3 is the ICD-10-CM diagnosis code for poisoning by thyroid hormones and substitutes, assault. It belongs to category T38 (poisoning by, adverse effect of and underdosing of hormones and their synthetic substitutes and antagonists, not elsewhere classified), 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 3 subcodes must be used instead.

Within T38.1X (poisoning by, adverse effect of and underdosing of thyroid hormones and substitutes), T38.1X3 is specifically for poisoning by thyroid hormones and substitutes, assault. Related codes cover poisoning by thyroid hormones and substitutes, accidental (unintentional) (T38.1X1), poisoning by thyroid hormones and substitutes, intentional self-harm (T38.1X2), poisoning by thyroid hormones and substitutes, undetermined (T38.1X4), adverse effect of thyroid hormones and substitutes (T38.1X5) and underdosing of thyroid hormones and substitutes (T38.1X6).

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
