Sprain of anterior cruciate ligament of left knee, sequela

This code signifies a chronic or late effect resulting from a previous injury to the anterior cruciate ligament (ACL) in the left knee. It indicates that the patient is experiencing ongoing symptoms or complications directly attributable to an old ACL sprain, rather than an acute or current injury. This could include persistent instability, pain, or functional limitations.

This code is appropriate when a patient presents with residual problems stemming from a past sprain of the left knee's anterior cruciate ligament. It should be used for follow-up care, rehabilitation, or management of long-term sequelae after the initial acute injury has healed. Do not use this code for an initial or acute ACL sprain.

• Always use in conjunction with a code describing the specific sequela (e.g., chronic pain, instability).
• Ensure documentation clearly states the condition is a "sequela" or "late effect" of a previous ACL sprain.
• Verify the laterality (left knee) is accurately documented.
