Underdosing of synthetic cannabinoids, sequela

This code indicates a patient is experiencing a long-term consequence or complication arising from the insufficient administration or cessation of synthetic cannabinoids. These sequelae are the residual effects that persist after the acute underdosing event has passed.

Use this code when documenting conditions such as chronic withdrawal symptoms, persistent psychological disturbances, or lasting organ damage directly attributable to a past underdosing of synthetic cannabinoids. This code is appropriate for follow-up encounters addressing these enduring health problems.

• Requires a seventh character "S" to denote sequela, indicating the long-term nature of the condition.
• Always code the specific sequela (e.g., chronic psychosis, persistent anxiety) first, followed by this underdosing code.
• Ensure documentation clearly links the current condition to a previous underdosing event of synthetic cannabinoids.
