Contusion of left knee, subsequent encounter

This code signifies a bruise to the left knee that is being treated or evaluated after the initial injury. It indicates that the patient is in the healing phase, receiving follow-up care, or experiencing complications from the initial contusion.

Apply this code when a patient presents for a follow-up visit related to a previously diagnosed left knee contusion. This includes scenarios such as re-evaluation of pain, assessment of healing progress, or management of persistent symptoms after the initial encounter.

• Ensure documentation clearly indicates a subsequent encounter for the left knee contusion.
• Verify laterality (left knee) is explicitly stated in the medical record.
• Do not use this code for the initial treatment of the injury; use the appropriate initial encounter code instead.
