Underdosing of synthetic cannabinoids, subsequent encounter

This code signifies that a patient is experiencing the effects of taking less than the prescribed or recommended amount of a synthetic cannabinoid during an ongoing course of treatment. This underdosing is causing a medical issue or requiring further clinical attention.

Apply this code when a patient presents for follow-up care related to complications or inadequate therapeutic effect due to insufficient intake of synthetic cannabinoids. This could include scenarios where the patient intentionally or unintentionally took too little, leading to a recurrence of symptoms or treatment failure.

• This "D" seventh character indicates a subsequent encounter for care after the acute phase of underdosing.
• Always sequence this code after the code(s) for the specific condition being treated with the synthetic cannabinoid, if applicable.
• Ensure documentation clearly supports underdosing as the cause of the patient's current clinical presentation.
