Adverse effect of ganglionic blocking drugs, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to a ganglionic blocking drug. These are typically persistent symptoms or complications that remain after the acute effects of the drug have resolved. Examples include chronic hypotension, persistent gastrointestinal issues, or neurological deficits.

Apply this code when documenting a patient's current condition that is a direct, lasting consequence of a previous adverse effect from a ganglionic blocking agent. This is used for conditions that are no longer acute but represent a permanent or chronic sequela. It should be used in conjunction with a code for the specific sequela.

• Always sequence this code after the code describing the specific sequela (e.g., chronic orthostatic hypotension).
• Ensure documentation clearly links the current condition to a past adverse effect of a ganglionic blocking drug.
• Do not use for acute adverse effects; those would be coded with an A or D seventh character.
