Toxic effect of manganese and its compounds, undet, subs

This code signifies a toxic reaction to manganese or its compounds, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is in the healing phase of the injury, receiving routine follow-up care, or experiencing a sequela of the initial poisoning.

Apply this code when documenting ongoing care for a patient previously diagnosed with manganese toxicity of unknown intent. This includes follow-up appointments, medication adjustments for chronic effects, or rehabilitation services after the initial acute phase has passed. It is used when the initial poisoning event is no longer the primary focus of treatment.

• Always sequence this code after the primary diagnosis for the specific manifestation of manganese toxicity.
• Ensure documentation clearly supports the "undetermined" intent and the "subsequent encounter" status.
• Do not use for initial acute poisoning; refer to the appropriate initial encounter code for undetermined intent.
