Toxic effect of phosphorus and its compnd, slf-hrm, sequela

This code signifies a long-term or residual health problem resulting from a deliberate act of self-poisoning with phosphorus or its compounds. These sequelae can manifest as chronic organ damage (e.g., liver, kidney, neurological) or persistent functional impairments that developed after the acute toxic event has resolved.

Use this code when documenting a patient presenting with a current health condition that is a direct consequence of a past, intentional self-harm attempt involving phosphorus. This applies to follow-up encounters where the acute poisoning has passed, but its lasting effects are being treated or monitored. It would not be used for the initial acute poisoning episode.

• Always sequence this sequela code after the code for the specific residual condition (e.g., chronic liver failure).
• Ensure documentation clearly links the current condition to a past intentional phosphorus poisoning.
• Do not use this code for acute toxic effects; use the appropriate acute poisoning code for the initial encounter.
