Oth injury due to oth acc on board unpowr wtrcrft, sequela

This code indicates a long-term health condition or complication resulting from an injury sustained during an accident on an unpowered watercraft other than a canoe, kayak, rowboat, or raft. This includes conditions that manifest or persist after the acute phase of the original injury has passed.

Apply this code when documenting a sequela (e.g., chronic pain, limited range of motion, scar tissue, nerve damage) directly attributable to an injury that occurred on an unpowered watercraft such as a paddleboard, sailboat, or pedal boat. This code is appropriate for follow-up encounters addressing these residual effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., M25.511 for chronic shoulder pain).
• Ensure documentation clearly links the current condition to the past injury on the specified type of watercraft.
• The "S" in the 7th character indicates sequela, meaning the patient is seen for the residual effect of a past injury, not the acute injury itself.
