Underdosing of methamphetamines, sequela

This code signifies a long-term consequence or complication arising from the insufficient administration or intake of methamphetamines. It indicates that the patient previously experienced an underdosing event, and the current clinical presentation is a direct result of that past occurrence. This could involve chronic withdrawal symptoms, persistent physiological imbalances, or other lasting health issues.

Apply this code when documenting a patient presenting with a current health problem that is a direct and lasting sequela of a previously documented or inferred underdosing of methamphetamine. This is appropriate for conditions that are not acute but rather chronic or residual effects. Examples include persistent neurological deficits, chronic mood disorders, or organ damage attributed to prolonged insufficient dosing.

• Requires a seventh character "S" to indicate sequela, meaning the patient is seen for the residual effect of the underdosing, not the acute event itself.
• Always sequence this code after the code(s) for the specific manifestation(s) of the sequela.
• Ensure documentation clearly links the current condition to a past methamphetamine underdosing event.
