Underdosing of predominantly alpha-adrenocpt agonists, init

This code signifies a patient experiencing adverse effects or a lack of therapeutic response due to receiving an insufficient dose of a predominantly alpha-adrenoreceptor agonist medication. This underdosing can lead to the persistence or worsening of the condition the medication was intended to treat.

Use this code when a patient presents with symptoms or a condition that is inadequately controlled because they did not receive enough of a prescribed alpha-agonist. This includes situations where the patient self-administered too little medication, or if a prescribed dose was insufficient for their clinical needs.

• Always assign an additional code for the specific adverse effect or condition being treated that is not responding to the underdosed medication.
• Ensure documentation clearly specifies "underdosing" rather than "noncompliance" if the patient intentionally took less than prescribed.
• The "A" in the seventh character indicates an initial encounter for this underdosing event.
