Underdosing of local astringents and local detergents, init

This code signifies that a patient has received less than the prescribed or recommended amount of a topical medication acting as an astringent (to constrict tissues) or a detergent (to cleanse or emulsify). This underdosing has led to an adverse effect or a worsening of the condition for which the medication was intended.

Apply this code when documentation clearly indicates that a patient's condition is exacerbated or not improving due to insufficient application or administration of a local astringent or detergent. This is appropriate for the initial presentation of the adverse effect or complication stemming from the underdosing.

• Ensure the documentation explicitly states "underdosing" and specifies a local astringent or detergent.
• Always assign an additional code for the specific adverse effect or complication resulting from the underdosing.
• Verify that this is the patient's first encounter for this particular underdosing event and its related adverse effect.
