Other contact with other nonvenomous marine animals, sequela

This code signifies a long-term or late-developing health problem resulting from an encounter with a nonvenomous marine animal other than those specifically classified (e.g., jellyfish, starfish, sea urchins). The initial injury or exposure has resolved, but residual effects or complications persist.

Apply this code when documenting conditions such as chronic dermatitis, persistent scarring, or ongoing pain directly attributable to a past contact with an unspecified nonvenomous marine animal. This is appropriate for follow-up visits where the primary focus is managing these lasting effects, not the acute injury itself.

• Always sequence this code after the code describing the specific sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to a past encounter with a nonvenomous marine animal.
• Do not use for acute injuries; refer to the initial encounter codes for those situations.
