Cystic meniscus, anterior horn of lat mensc, right knee

This code identifies a fluid-filled sac or lesion located within the anterior portion of the lateral meniscus in the right knee. This condition can cause pain, swelling, and mechanical symptoms such as clicking or locking in the knee joint. It represents a specific anatomical location and type of meniscal pathology.

This code is appropriate when documentation clearly indicates a cystic lesion affecting the anterior horn of the right lateral meniscus, confirmed by imaging (e.g., MRI) or arthroscopy. It applies to patients presenting with symptoms attributable to this specific meniscal cyst.

• Ensure laterality (right knee) and specific meniscal horn (anterior horn of lateral meniscus) are clearly documented.
• Distinguish from other meniscal tears or degenerative conditions; this code is for a cystic lesion.
• Consider sequencing with codes for associated symptoms (e.g., knee pain, swelling) if documented.
