Contact with prime movers, sequela

This code indicates a health condition or injury that is a late effect or complication resulting from an initial contact with a prime mover. A prime mover is a machine that converts energy into mechanical work, such as an engine, motor, or turbine. The sequela could manifest long after the initial incident, representing a chronic or permanent consequence.

Use this code when documenting a condition that is a direct result of a past injury involving a prime mover, and the acute phase of the original injury has resolved. Examples include chronic pain, nerve damage, or functional impairment directly attributable to a prior incident with an engine or other prime mover. This code is appropriate when the patient is no longer receiving active treatment for the initial injury itself, but rather for its lasting effects.

• Always sequence the code for the specific sequela (e.g., chronic pain, scar, amputation status) first, followed by this external cause code.
• Ensure documentation clearly links the current condition to a past contact with a prime mover.
• This "S" seventh character indicates sequela and should only be used for conditions that are residual effects of a past injury.
