Underdosing of local astringents and local detergents, sequela. This code represents a condition resulting from a previous underdosing of local astringents and detergents. Astringents and detergents are substances used for their cleansing and constricting properties, and underdosing can lead to various complications.

Example 1: A patient had a minor skin abrasion that required a local astringent for wound healing. Due to underdosing, the wound didn’t heal properly and developed a chronic infection, now requiring further treatment., A patient with a skin rash was prescribed a local detergent to cleanse the affected area. Insufficient dosage led to persistent irritation and secondary infection, resulting in a chronic skin condition., A patient with a mouth sore was prescribed a local astringent. The underdosing led to the sore not healing correctly, developing into a chronic ulcer that now requires more intensive treatment.

Documentation should include details about the initial incident of underdosing, the specific astringent or detergent involved, and the subsequent condition or sequela that developed as a direct result of the underdosing. Any related treatments or interventions should also be documented.
