Toxic effect of organophos and carbamate insect, undet, subs

This code indicates a toxic reaction to organophosphate or carbamate insecticides where the intent (e.g., accidental, intentional self-harm, assault) is not documented or cannot be determined. The patient is receiving follow-up care for the effects of this poisoning after the initial treatment.

Use this code for subsequent encounters when a patient presents with ongoing symptoms or complications from organophosphate or carbamate insecticide poisoning, and the circumstances surrounding the exposure remain unclear. This applies to situations where the initial encounter code would have been for an "undetermined" intent.

• Requires an additional code for the specific manifestation(s) of the poisoning.
• The 7th character "D" signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Ensure documentation clearly supports the "undetermined" intent and the follow-up nature of the visit.
