Poisn by unsp sys anti-infect and antiparastc, asslt, sqla

This code describes a long-term health problem or complication resulting from a past poisoning event involving an unspecified systemic anti-infective or antiparasitic medication. The poisoning was intentionally inflicted by another person (assault). The "sequela" 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 chronic or residual symptoms directly attributable to a past assault by poisoning with an anti-infective/antiparasitic. This applies to follow-up visits where the focus is on managing the lasting effects, rather than the initial acute poisoning. Examples include ongoing organ damage, neurological deficits, or other persistent health issues.

• Always use this code as a secondary diagnosis, following a code for the specific sequela (e.g., chronic kidney disease, neuropathy).
• Ensure the medical record clearly documents the assaultive nature of the poisoning and the causal link between the past event and the current sequela.
• Verify that the anti-infective or antiparasitic agent was truly unspecified if a more specific substance is known, a more precise code should be used.
