Poisn by insulin and oral hypoglycemic drugs, undet, sequela

This code signifies a long-term health problem or condition that has resulted from an overdose or adverse reaction to insulin or oral antidiabetic medications, where the intent (e.g., accidental, intentional self-harm) of the poisoning cannot be determined. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual effects.

Use this code when documenting a patient presenting with a chronic complication or sequela directly attributable to a past poisoning event involving insulin or oral hypoglycemic drugs, and the circumstances surrounding the original poisoning were not clearly established. This applies to follow-up encounters for conditions like persistent neurological damage, organ dysfunction, or chronic metabolic derangements stemming from the undetermined poisoning.

• Always ensure the medical record clearly links the current sequela to a past poisoning event by insulin or oral hypoglycemic agents.
• This code requires a seventh character 'S' for sequela, indicating the long-term nature of the condition.
• Do not use this code for acute poisoning events; instead, refer to the appropriate acute poisoning codes.
