Sprain of anterior cruciate ligament of left knee, subs

This diagnosis code indicates a sprain of the anterior cruciate ligament (ACL) in the left knee. It signifies that the patient is in the healing phase of the injury, receiving follow-up care, or experiencing a complication from the initial sprain.

Apply this code when a patient presents for ongoing treatment, rehabilitation, or a follow-up visit related to a previously diagnosed left ACL sprain. This includes scenarios such as physical therapy sessions, re-evaluation of healing progress, or management of persistent symptoms after the initial acute injury.

• Ensure documentation clearly states "left knee" and "anterior cruciate ligament" to support this specific code.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use for initial injury encounters; those require an "A" (initial encounter) seventh character.
