Struck by other nonvenomous marine animals, sequela

This code indicates a past injury resulting from contact with a nonvenomous marine animal, excluding those specifically categorized elsewhere (e.g., sharks, stingrays). It signifies that the patient is experiencing residual effects or complications from such an encounter, rather than the acute injury itself.

Apply this code when documenting a patient presenting with long-term issues, such as chronic pain, scarring, infection, or functional impairment, directly attributable to a prior incident involving a nonvenomous marine animal. This is appropriate for follow-up visits addressing these sequelae after the initial acute injury has resolved.

• Always use in conjunction with a code describing the specific sequela (e.g., chronic pain, scar, infection).
• Ensure the medical record clearly links the current condition to the past marine animal encounter.
• Do not use for acute injuries; refer to the acute injury codes in the W56 category for initial encounters.
