Adverse effect of coronary vasodilators, sequela

This code signifies a lasting or residual condition resulting from an adverse reaction to a coronary vasodilator medication. These are effects that persist after the acute adverse event has resolved, indicating a chronic or permanent consequence of the drug.

Apply this code when documenting a patient presenting with a long-term health problem directly attributable to a past adverse effect of a coronary vasodilator. Examples include chronic hypotension, persistent neurological deficits, or organ damage that developed as a sequela of the drug's adverse action.

• Always use this code as a secondary diagnosis, following the code for the specific sequela.
• Ensure documentation clearly links the current condition to a prior adverse effect of a coronary vasodilator.
• Do not use for acute adverse effects; those require codes from the initial encounter or subsequent encounter categories.
