Poisoning by local astringents/detergents, undet, subs

This code signifies a poisoning event involving substances like local astringents or detergents, where the intent (accidental, intentional self-harm, assault) cannot be determined. The "subsequent encounter" indicates that the patient is receiving follow-up care for the sequelae or ongoing management of this poisoning, not the initial acute treatment.

Use this code when a patient presents for ongoing treatment, monitoring, or evaluation related to a previous poisoning by a local astringent or detergent, and the circumstances surrounding the poisoning remain unclear. This applies to situations where the initial acute phase has passed, and the patient is now in a recovery or management phase.

• Always ensure the "undetermined" intent is clearly documented by the provider.
• Verify that the encounter is indeed "subsequent" and not the initial treatment for the poisoning.
• Pair this code with additional codes for any specific symptoms, injuries, or conditions resulting from the poisoning.
