Sprain of lateral collateral ligament of left knee, init

This code signifies an injury to the lateral collateral ligament (LCL) on the outer side of the left knee, characterized by stretching or tearing of the ligament fibers. It represents a sprain, which is a less severe injury than a complete rupture. This specific code is for the initial treatment or evaluation of the injury.

Use this code for patients presenting with a newly diagnosed LCL sprain of the left knee, such as after a varus stress injury to the knee. It is appropriate for the first visit where the injury is assessed, diagnosed, and a treatment plan is initiated. This code would be used for the initial encounter regardless of whether the patient is seen in an emergency department, urgent care, or physician's office.

• Ensure documentation clearly specifies the left knee and lateral collateral ligament.
• Confirm the encounter is the initial treatment for this specific injury; subsequent encounters will use a different seventh character.
• Distinguish between a sprain (stretching/partial tear) and a complete rupture, as ruptures have different codes.
