Bitten by other marine mammals, subsequent encounter

This code indicates that a patient has sustained an injury from the bite of a marine mammal, excluding those specifically categorized elsewhere (e.g., sharks, killer whales), and is presenting for follow-up care after the initial treatment. This could include bites from seals, sea lions, dolphins (other than killer whales), or manatees. The subsequent encounter designation signifies ongoing management of the injury, such as wound checks, dressing changes, or evaluation of complications.

Apply this code when a patient returns for medical attention related to a marine mammal bite that was initially treated on a previous visit. This includes scenarios where the patient is being seen for infection surveillance, wound debridement, or assessment of healing progress. It is also appropriate for visits addressing delayed complications directly attributable to the original bite.

• Always pair this code with an external cause code (e.g., Y92.830 for ocean and coastal waters) to provide a complete picture of the incident.
• Ensure documentation clearly indicates that this is not the initial encounter for the bite injury.
• Specify the exact type of marine mammal if known and documented, as this may influence other coding decisions or clinical management.
