Oth meniscus derangements, unsp lateral meniscus, right knee

This code describes a non-specific derangement or abnormality of the lateral meniscus in the right knee. It indicates a problem with the meniscus that is not further specified as a tear, cyst, or other defined lesion.

This code is appropriate when documentation indicates a derangement of the right lateral meniscus but lacks specific details regarding the nature of the derangement (e.g., "lateral meniscal derangement, right knee"). It is used when the provider has not identified a specific type of meniscal injury or pathology.

• Only use this code when the documentation explicitly states "unspecified" or lacks further detail about the meniscal derangement.
• Always strive for greater specificity if available in the medical record (e.g., M23.231 for a complex tear of the lateral meniscus, right knee).
• Ensure laterality (right knee) is clearly documented to support the use of this specific code.
