Underdosing of antipruritics, initial encounter

This code indicates that a patient has received less than the prescribed or therapeutically effective dose of a medication intended to relieve itching. This underdosing has resulted in an adverse effect or a worsening of the underlying condition for which the antipruritic was prescribed.

Use this code when a patient presents with persistent or exacerbated pruritus due to insufficient administration of an antipruritic medication. This applies to situations where the patient did not take enough of the drug, or the prescribed dose was inadequate to manage their symptoms, and this is the first time the underdosing is being addressed.

• Always sequence this code after the code(s) for the specific adverse effect or condition being treated.
• Ensure documentation clearly states the underdosing of an antipruritic and its impact on the patient's condition.
• Verify that "initial encounter" is appropriate, meaning the patient is receiving active treatment for the underdosing event.
