Oth tear of medial meniscus, current injury, l knee, sequela

This code signifies a chronic or late effect of a tear to the medial meniscus in the left knee, which was sustained as a current injury. It indicates that the patient is experiencing ongoing symptoms or complications directly attributable to that past meniscal tear. This is not for an acute injury, but rather for the long-term consequences.

Apply this code when documenting a patient presenting with persistent pain, instability, locking, or other residual issues in the left knee, where the underlying cause is a previously diagnosed and treated (or untreated) medial meniscus tear from a current injury. This is appropriate for follow-up visits addressing the sequelae of the initial tear, rather than the initial injury itself.

• Ensure documentation clearly states the current symptoms are a direct result of a prior medial meniscus tear.
• Do not use for acute or initial injury encounters; those require codes without the "S" seventh character.
• Confirm the tear is specifically of the medial meniscus and in the left knee.
