Underdosing of coronary vasodilators, sequela

This code indicates that a patient is experiencing a long-term consequence or complication due to not receiving an adequate dose of a coronary vasodilator medication. This underdosing has led to a persistent health issue that is now being addressed.

Use this code when documenting a patient presenting with a chronic or residual condition directly attributable to a past insufficient administration of a coronary vasodilator. This typically applies to follow-up encounters for ongoing management of the sequela.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Requires a seventh character "S" to denote sequela, indicating the long-term nature of the condition.
• Ensure documentation clearly links the current condition to the previous underdosing of the medication.
