Sprain of lateral collateral ligament of right knee, init

This diagnosis code indicates a stretching or tearing injury to the lateral collateral ligament (LCL) on the outside of the right knee. This ligament helps stabilize the knee joint, preventing excessive outward movement. The "initial encounter" signifies that the patient is receiving active treatment for this specific injury.

Use this code for patients presenting with a newly diagnosed or acutely treated sprain of the right knee's LCL. This applies to situations such as an emergency room visit, an initial orthopedic consultation, or the first few follow-up visits during the acute phase of treatment. It is appropriate when the patient is actively undergoing care for the injury.

• Ensure documentation specifies the right knee and the lateral collateral ligament.
• Confirm the encounter is for active treatment of the injury, not for sequelae or follow-up after the acute phase.
• Look for details on the mechanism of injury (e.g., varus stress to the knee) to support the diagnosis.
