Adverse effect of tetracyclines, subsequent encounter

This code signifies a harmful or undesirable reaction experienced by a patient due to the therapeutic use of a tetracycline antibiotic, occurring during a follow-up visit for the adverse effect. It indicates that the initial treatment of the adverse effect has concluded, and the patient is now receiving routine care during the recovery phase.

Use this code when a patient presents for ongoing management or monitoring of an adverse effect from a tetracycline, such as persistent photosensitivity, gastrointestinal upset, or dental staining, after the acute phase of treatment has passed. This applies to situations where the patient is still experiencing symptoms or complications from the adverse reaction and is being seen for continued care.

• Always sequence the adverse effect code first, followed by codes for the specific manifestation of the adverse effect.
• Ensure documentation clearly states the adverse effect is due to a tetracycline and that the encounter is for follow-up care.
• Distinguish from "initial encounter" (A) and "sequela" (S) based on the stage of treatment and recovery for the adverse effect.
