Underdosing of local antifung/infect/inflamm drugs, sequela

This code indicates that a patient has experienced a long-term consequence or complication due to receiving an insufficient amount of a topical antifungal, anti-infective, or anti-inflammatory medication. The underdosing itself is no longer the active problem, but its lasting effects are being addressed.

Apply this code when documenting conditions that are a direct result of a past underdosing of a local antifungal, anti-infective, or anti-inflammatory drug. Examples include chronic or recurrent infections, persistent inflammation, or tissue damage that occurred because the initial treatment was inadequate. This code is appropriate when the patient is being treated for the residual effects, not the acute underdosing event.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a previous underdosing of a local medication from the specified drug classes.
• Do not use this code for acute underdosing; it is exclusively for long-term effects.
