Toxic effect of phosphorus and its compnd, assault, sequela

This code signifies the long-term, residual health problems resulting from a past poisoning by phosphorus or its compounds, specifically when the poisoning was intentionally inflicted by another person. These sequelae can manifest in various organ systems, depending on the initial severity and route of exposure.

Use this code when documenting chronic conditions, disabilities, or permanent organ damage that are directly attributable to a prior phosphorus poisoning that occurred as an assault. This applies to follow-up encounters for managing these lasting effects, not for the initial acute poisoning event.

• Always sequence this sequela code after the code for the specific residual condition(s) being treated.
• Ensure documentation clearly links the current condition to the past phosphorus poisoning and specifies the assault intent.
• Do not use for acute poisoning or accidental/intentional self-harm exposures.
