Underdosing of local astringents and local detergents, subs

This code indicates that a patient is experiencing a negative health consequence due to receiving an insufficient amount of a topically applied astringent or detergent. This underdosing is not the initial event but is being addressed during a follow-up visit for the related adverse effect.

Use this code when a patient presents for ongoing management of a condition, such as dermatitis or an infection, that has worsened or failed to improve because they did not receive or apply enough of a prescribed local astringent or detergent. This applies to situations where the underdosing is identified or managed during a subsequent encounter.

• Always assign an additional code for the specific adverse effect or condition resulting from the underdosing.
• Ensure documentation clearly supports that the underdosing occurred and that this is not the first time the patient is being seen for this particular issue.
• Distinguish from initial encounters (A) or sequela (S) encounters; the "D" indicates subsequent care for the underdosing effect.
