Poisoning by antitussives, intentional self-harm, sequela

This code indicates a long-term consequence or residual effect resulting from a deliberate act of self-poisoning with antitussive medications. These sequelae can manifest in various organ systems, even after the acute phase of the poisoning has resolved. Examples include chronic respiratory issues, neurological damage, or persistent gastrointestinal problems.

Apply this code when documenting a patient presenting with a current health condition that is a direct, lasting result of a past intentional self-harm overdose of cough suppressants. This code is appropriate for follow-up care or when the sequela is the primary reason for the current encounter, rather than the acute poisoning event itself.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past intentional antitussive poisoning.
• Do not use this code for the acute poisoning event; use the acute poisoning code with the appropriate seventh character for that scenario.
