Underdosing of thrombolytic drugs, sequela

This code signifies a patient experiencing a long-term consequence or complication directly attributable to receiving an insufficient dose of a thrombolytic medication. These sequelae are the residual effects that persist after the acute phase of the underdosing event has passed.

Use this code when documenting conditions like chronic organ damage, persistent neurological deficits, or recurrent thrombotic events that are determined to be a direct result of inadequate thrombolytic therapy administered in the past. This applies when the patient is no longer in the acute phase of the underdosing itself, but rather presenting with its lasting impact.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past underdosing of a thrombolytic agent.
• A seventh character "S" indicates sequela, meaning the residual effect of a past injury or illness.
