Prsn brd/alit a car inj in clsn w nonmtr vehicle, sequela

This code describes the long-term effects or complications arising from an injury sustained by an individual who was in the process of getting into or out of a car, and that car was involved in a collision with a non-motorized vehicle (e.g., bicycle, animal-drawn vehicle, streetcar). It signifies that the initial injury has led to a subsequent condition or symptom that requires ongoing medical attention.

Use this code when documenting a sequela, such as chronic pain, scar tissue, limited range of motion, or neurological deficits, that is directly attributable to an injury sustained during a car-nonmotor vehicle collision while the patient was boarding or alighting. This code is appropriate for encounters occurring long after the initial acute injury has healed, but the patient continues to experience related health problems.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, arthritis).
• Ensure documentation clearly links the current condition to the past collision event and the patient's status (boarding/alighting).
• Remember the "S" seventh character indicates sequela, meaning the residual effects of a past injury.
