Cmplx tear of lat mensc, current injury, unsp knee, sequela

This code signifies a complex tear of the lateral meniscus that occurred in the past and is now presenting with residual effects or complications. A complex tear involves multiple planes or patterns of tearing within the meniscus, making it more intricate than simple longitudinal or radial tears. This particular code specifies that the injury's exact location within the knee is not documented.

Apply this code when a patient presents with ongoing symptoms or sequelae directly attributable to a previously sustained complex lateral meniscal tear. This includes chronic pain, instability, locking, or functional limitations that persist after the initial injury and treatment. It is appropriate for follow-up visits where the focus is on managing the long-term effects of the tear.

• Ensure documentation clearly states "sequela" or indicates a chronic condition resulting from a past complex lateral meniscal tear.
• Do not use for acute or initial injury encounters; those require codes from the "A" or "D" seventh character categories.
• If the specific knee (right or left) is documented, choose the more precise code (S83.271S or S83.272S).
