Underdosing of beta-adrenoreceptor antagonists, init encntr

This code signifies that a patient has received an insufficient amount of a beta-blocker medication, leading to a suboptimal therapeutic effect. This underdosing can result in uncontrolled symptoms or worsening of the condition the beta-blocker is intended to treat. The "initial encounter" designation indicates this is the first time the patient is being seen for this specific underdosing event.

Use this code when a patient presents with symptoms or signs indicating their beta-blocker medication is not adequately controlling their condition due to a dose that is too low. This may occur if the prescribed dose is insufficient, if the patient is not taking the medication as directed, or if the medication is being absorbed poorly. It is appropriate for the initial assessment and management of this underdosing.

• Always sequence this code after the code for the condition being treated by the beta-blocker (e.g., hypertension, angina).
• Do not use this code if the patient is experiencing an adverse effect or poisoning from the beta-blocker; use codes from T44.7X1-T44.7X4 instead.
• Ensure documentation clearly supports that the issue is an underdosing and not a complete non-compliance or a medication error leading to no administration.
