Toxic effect of contact w oth jellyfish, self-harm, sequela

This code signifies a long-term or late-appearing health problem resulting from a deliberate act of self-harm involving contact with a type of jellyfish other than Portuguese man-of-war. The initial injury has resolved, but residual effects or complications persist. This indicates a past event with ongoing clinical significance.

Apply this code when documenting a patient presenting with a chronic condition or permanent damage directly attributable to a previous, intentional self-inflicted jellyfish sting (excluding Portuguese man-of-war). This is appropriate for follow-up encounters where the sequelae are being managed, rather than the acute toxic effect.

• Always assign this "S" (sequela) code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past intentional jellyfish exposure.
• Do not use this code for acute toxic effects; those require an "A" (initial encounter) or "D" (subsequent encounter) character.
