Poisoning by sulfonamides, assault, sequela

This code signifies a long-term or residual effect resulting from a poisoning by sulfonamide antibiotics that occurred due to an intentional assault. It indicates that the patient is experiencing ongoing health issues directly attributable to the past toxic exposure.

Apply this code when documenting a patient presenting with chronic conditions or permanent damage, such as kidney failure, liver damage, or neurological deficits, that are a direct consequence of a previous sulfonamide poisoning inflicted during an assault. This code is used after the acute phase of the poisoning has resolved and the patient is being treated for the lasting effects.

• Always sequence this code after the code for the specific sequela being treated (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to a past sulfonamide poisoning and specifies the assault intent.
• Do not use for acute poisoning episodes; this code is exclusively for sequelae.
