Underdosing of local astringents/detergents, sequela

This code signifies a long-term consequence or complication arising from the insufficient administration or use of local astringents or detergents. These substances are typically applied topically for their drying, constricting, or cleansing properties. The sequela indicates that the original underdosing event is no longer active, but its lasting effects are still present and being treated.

Use this code when documenting a condition that is a direct result of a past underdosing of a local astringent or detergent. Examples include chronic skin irritation, persistent infection, or delayed wound healing attributed to the inadequate application of these agents. This code is appropriate when the acute underdosing event has resolved, but its lingering impact requires ongoing management.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past underdosing of a local astringent or detergent.
• The "S" seventh character indicates sequela, meaning the residual effect of the underdosing, not the acute event itself.
