Adverse effect of antigonadtr/antiestr/antiandrg, NEC, subs

This code signifies a patient experiencing an unintended and harmful reaction to medications that suppress gonadotropin, estrogen, or androgen activity. These adverse effects are not classified elsewhere and are being managed during a follow-up visit after the initial treatment of the adverse effect.

Apply this code when a patient presents for ongoing management or evaluation of an adverse reaction to anti-gonadotropin, anti-estrogen, or anti-androgen therapy (e.g., tamoxifen, leuprolide) that was previously identified and treated. This would include scenarios like monitoring liver function abnormalities, persistent hot flashes, or bone density changes attributed to the drug, during a subsequent encounter.

• Requires an additional code to identify the specific drug causing the adverse effect (T36-T50 with 5th or 6th character 5).
• Use for follow-up care related to the adverse effect, not for the initial presentation or acute phase.
• Distinguish from poisoning (T36-T50 with 5th or 6th character 1-4) or underdosing (T36-T50 with 5th or 6th character 6).
