Adverse effect of hormones and synthetic substitutes, subs

This code signifies a patient experiencing an unintended and harmful reaction to a hormone or synthetic substitute, excluding adrenal cortical steroids, androgens, estrogens, and progestins. This adverse effect is being addressed during an encounter subsequent to the initial treatment of the adverse reaction.

Apply this code when a patient presents for follow-up care, monitoring, or continued management of an adverse effect caused by medications such as thyroid hormones, growth hormones, or antidiuretic hormones. This includes situations where the patient is still experiencing symptoms or complications from the initial adverse reaction.

• Ensure the encounter is for follow-up care of the adverse effect, not the initial treatment.
• Always code the specific adverse effect first, followed by this code to indicate the drug causing the reaction.
• Verify that the hormone or synthetic substitute involved is not one of the more specific categories (e.g., T38.0-T38.7).
