Contusion of right knee, initial encounter

This code signifies a bruise or superficial injury to the right knee, resulting from direct trauma without an open wound. It indicates damage to the soft tissues, such as skin and subcutaneous tissue, causing pain, swelling, and discoloration.

Apply this code for patients presenting with a new right knee contusion following an acute injury, such as a fall, direct impact, or sports-related trauma. This code is appropriate when the patient is receiving initial treatment for the injury.

• Ensure documentation specifies the right knee and confirms a contusion rather than a sprain, strain, or fracture.
• Verify that this is the patient's first encounter for this specific injury; subsequent encounters will require a different seventh character.
• Do not use for open wounds, dislocations, or fractures of the knee.
