Adverse effect of other hormone antagonists, subs encntr

This code signifies an undesirable or harmful reaction experienced by a patient due to a medication that blocks the action of hormones, excluding specific categories like adrenal cortical hormones, oxytocic agents, or other specified hormone antagonists. The "subsequent encounter" indicates that the patient is receiving follow-up care for this adverse effect, not the initial treatment.

Use this code when a patient presents for ongoing management or monitoring of an adverse effect caused by a hormone antagonist not otherwise classified, such as certain anti-androgens or anti-estrogens. This applies after the initial diagnosis and treatment of the adverse reaction have been established.

• Always sequence this code after the code for the specific adverse effect (e.g., rash, nausea).
• Ensure the medication causing the adverse effect is documented as a hormone antagonist and is not more specifically classified elsewhere.
• Verify that the encounter is for follow-up care related to the adverse effect, not the initial presentation.
