Other contact with other marine mammals, subs encntr

This code signifies an injury or adverse health effect resulting from contact with a marine mammal other than a dolphin, killer whale, or sea lion, during a subsequent encounter for the same injury. This includes animals like seals, walruses, manatees, or other less common marine mammals. The initial injury or condition has already been treated, and the patient is now receiving follow-up care.

Use this code for follow-up visits related to an injury sustained from contact with an unspecified marine mammal, such as a seal bite or a manatee collision. This applies when the patient is returning for wound care, physical therapy, or re-evaluation of the initial injury. It indicates that the patient is in the healing phase or receiving ongoing management for the sequelae of the original incident.

• Always ensure this is a subsequent encounter (D) and not an initial (A) or sequela (S) encounter.
• Verify that the marine mammal involved is not a dolphin, killer whale, or sea lion, as those have more specific codes.
• Pair this external cause code with an injury code (e.g., bite, contusion, fracture) to fully describe the patient's condition.
