Poisn by insulin and oral hypoglycemic drugs, undet, subs

This code signifies a poisoning event involving insulin or oral hypoglycemic medications where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. It specifically applies to encounters following the initial treatment of the poisoning, indicating ongoing care or follow-up. The patient is experiencing adverse effects from these medications, but the circumstances surrounding the exposure remain unclear.

Use this code for follow-up visits, hospital readmissions, or continued outpatient care for a patient who previously presented with poisoning from insulin or oral hypoglycemic drugs. The key is that the intent of the poisoning was documented as "undetermined" during the initial encounter, and this uncertainty persists. This code is appropriate when the patient is still being managed for the effects of the poisoning.

• Always assign an additional code for the specific manifestation of the poisoning (e.g., hypoglycemia, coma).
• Ensure documentation clearly states "undetermined" intent for the poisoning; otherwise, a different intent code should be selected.
• This "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
