Advrs effect of local antifung/infect/inflamm drugs, sequela

This code signifies a long-term or residual condition resulting from an adverse reaction to a topically applied medication intended to treat fungal infections, other infections, or inflammation. It indicates that the initial adverse effect has resolved, but a lasting consequence or complication remains.

Use this code when documenting a persistent problem, such as scarring, chronic dermatitis, or permanent discoloration, that is directly attributable to a past adverse reaction to a local antifungal, anti-infective, or anti-inflammatory drug. This code is appropriate when the acute adverse event has passed, but its sequelae are still present and require ongoing management or documentation.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current sequela to a previously experienced adverse effect of the specified drug class.
• Do not use this code for acute adverse reactions; those require the appropriate acute adverse effect code.
