In simple words: This code describes the long-term effects of a previous break in the left kneecap (patella), a condition that isn't covered by other, more specific codes.

Sequela of other fracture of left patella. This condition is a late effect (sequela) resulting from a fracture of the left patella that is not described by other codes in this category. The fracture could be due to various reasons, like a fall, direct blow, or sports injury. The "S" at the end signifies that it is a sequela.

Example 1: A patient experiences chronic pain and stiffness in their left knee several months after sustaining a patellar fracture that was not a simple transverse, longitudinal, comminuted, or osteochondral fracture., A patient has limited range of motion in their left knee a year after a complex patellar fracture, now healed, that involved multiple fragments and required surgical repair, but is not classified as one of the specific fracture types., A patient presents with persistent instability in their left knee following a healed patellar fracture of an unspecified nature, different from the typical fracture patterns.

Documentation should support the presence of long-term effects due to a prior fracture of the left patella. The nature of the original injury, treatment provided, and the current presenting symptoms impacting function should be detailed.
