Adverse effect of antimycobacterial drugs, subs encntr

This code signifies a patient experiencing an unintended and undesirable reaction to medication used to treat mycobacterial infections, such as tuberculosis or leprosy, during a follow-up visit or ongoing treatment. The adverse effect is not due to poisoning, overdose, or improper administration, but rather a known or unexpected side effect of the drug itself.

This code is appropriate for documenting subsequent encounters where a patient is being monitored or treated for an adverse effect that developed from antimycobacterial drug therapy. Examples include follow-up appointments for drug-induced hepatitis, neuropathy, or skin rashes that occurred as a result of medications like isoniazid, rifampin, or ethambutol.

• Always sequence the code for the specific adverse effect first, followed by this code.
• Ensure the documentation clearly indicates the encounter is for the management of a previously identified adverse effect, not the initial presentation.
• Verify the drug causing the adverse effect is indeed an antimycobacterial agent.
