Poisoning by cannabis, intentional self-harm, sequela

This code signifies a long-term consequence or complication arising from a deliberate act of self-poisoning with cannabis. It indicates that the patient is experiencing a residual effect directly attributable to a past intentional overdose or misuse of cannabis.

Apply this code when documenting a patient presenting with a current condition or symptom that is a direct sequela of a previous intentional self-harm event involving cannabis. This could include chronic psychiatric issues, persistent neurological deficits, or other lasting health problems clearly linked to the past poisoning.

• Requires a seventh character "S" to denote sequela, indicating the residual effect of a previous injury or illness.
• Always sequence this code after the code(s) for the specific sequela being treated.
• Do not use for acute poisoning or for poisoning due to accidental or undetermined intent.
