Sprain of anterior cruciate ligament of right knee, init

This code signifies a tear or overstretching of the anterior cruciate ligament (ACL) in the right knee. This injury often results from sudden twisting, hyperextension, or direct impact to the knee, leading to instability and pain.

Apply this code for a patient presenting with a newly diagnosed ACL sprain of the right knee. This includes initial evaluations, emergency department visits, or the first encounter for treatment of this specific injury.

• Ensure documentation specifies the right knee; otherwise, an unspecified laterality code may be more appropriate.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Look for keywords like "sprain," "tear," "rupture," or "strain" of the ACL in the clinical notes.
