Prph tear of medial mensc, crnt injury, unsp knee, sequela

This code signifies a chronic or residual issue stemming from a past injury to the medial meniscus, specifically a peripheral tear. It indicates that the patient is experiencing ongoing problems related to this previous tear, rather than an acute event. The tear's location is on the outer edge of the medial meniscus, and the affected knee is not specified.

Use this code when documenting follow-up care, rehabilitation, or management of persistent symptoms (e.g., pain, instability, locking) directly attributable to an old peripheral tear of the medial meniscus. It applies when the initial injury has healed to some extent but continues to cause clinical sequelae. This code is appropriate for patients presenting with long-term complications from such a tear.

• Ensure documentation clearly states the injury is not acute and is a "sequela" or "old" injury causing current issues.
• Pair this code with an external cause code if the original injury mechanism is relevant and known.
• Do not use this code for acute or initial presentations of a medial meniscus tear; those require different codes.
