Underdosing of thrombolytic drugs, initial encounter

This code signifies that a patient has received an insufficient dose of a thrombolytic medication, leading to a suboptimal therapeutic effect. Thrombolytic drugs are used to dissolve blood clots, and underdosing can result in persistent or worsening thrombotic conditions. This specific code is for the initial encounter where the underdosing is identified or treated.

Apply this code when documentation indicates a patient was administered less than the prescribed or therapeutically effective amount of a thrombolytic agent. This could occur due to medication errors, patient non-compliance, or issues with drug delivery. Use for the initial visit where the underdosing is recognized and addressed.

• Always confirm the specific drug class is thrombolytic.
• Ensure the documentation clearly states "underdosing" or an insufficient amount was given.
• Remember the "A" suffix indicates an initial encounter for this condition.
