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

This code describes a chronic or late effect of a peripheral tear to the lateral meniscus, which is one of the C-shaped cartilages in the knee joint. The tear is located at the outer edge of the meniscus. This diagnosis indicates that the initial injury has resolved, but the patient is still experiencing residual symptoms or complications.

Use this code when documenting a patient presenting with ongoing issues, such as persistent pain, instability, or mechanical symptoms, that are directly attributable to a previously sustained peripheral lateral meniscus tear. This applies when the initial acute injury has passed the acute phase and the current encounter is for managing these long-term effects.

• Always ensure documentation clearly links current symptoms to the prior injury.
• Do not use for acute or initial encounters for a lateral meniscus tear; those require codes from the initial or subsequent encounter categories.
• Consider additional codes for specific residual symptoms (e.g., chronic pain, instability) if documented.
