Poisoning by digestants, assault, subsequent encounter

This code indicates a poisoning event resulting from the intentional administration of a digestant substance with harmful intent, where the patient is receiving follow-up care for the sequelae of the initial poisoning. Digestants are substances that aid in digestion, such as enzymes or antacids, but can be toxic in overdose or when misused. The "subsequent encounter" aspect signifies ongoing treatment or monitoring related to the initial assault.

Use this code for patients presenting for follow-up appointments, medication adjustments, or management of lingering symptoms (e.g., gastrointestinal damage, systemic effects) after being intentionally poisoned with a digestant. This applies when the initial acute care for the assault has concluded, and the patient is now in a recovery or rehabilitation phase.

• Always sequence this code after the primary diagnosis describing the specific manifestation of the poisoning (e.g., gastritis, esophageal burns).
• Ensure documentation clearly states the intent was assault and that this is not the initial encounter for the poisoning.
• Verify the substance involved is indeed a digestant; differentiate from other medications or chemicals.
