Other contact with other marine mammals, sequela

This code describes the long-term effects or complications arising from a past encounter with a marine mammal other than a whale, orca, or dolphin. These sequelae are the residual conditions that persist after the initial injury or event has resolved.

Apply this code when documenting conditions such as chronic pain, scarring, nerve damage, or psychological sequelae directly attributable to a previous injury or incident involving an unspecified marine mammal. This code is appropriate for follow-up encounters addressing these lasting effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past contact with an "other marine mammal."
• Do not use for acute injuries; this code is exclusively for the late effects of such encounters.
