Underdosing of antipruritics, subsequent encounter

This code indicates that a patient is experiencing adverse effects or complications because they are not taking enough of their prescribed antipruritic medication. This underdosing is occurring during a subsequent encounter for the condition.

Apply this code when a patient presents for follow-up care, and their current symptoms (e.g., persistent itching) are attributed to insufficient intake of their antipruritic medication. This could be due to patient non-compliance, misunderstanding of dosage instructions, or a deliberate reduction in dose.

• Always sequence this code after the code(s) for the specific condition being treated by the antipruritic.
• Ensure documentation clearly states that the underdosing is the cause of the current clinical presentation and that it's not the initial encounter for this specific underdosing issue.
• Distinguish from "initial encounter" (A) or "sequela" (S) by verifying the encounter type in the medical record.
