Unspecified dislocation of unspecified knee, sequela

This code indicates a long-term complication or late effect stemming from a prior, unspecified dislocation of an unspecified knee joint. It signifies that the original injury has resolved, but residual issues related to that dislocation are still present and being addressed.

Utilize this code when documenting a patient presenting with a current problem that is a direct consequence of an old, previously treated knee dislocation, where the specific type of dislocation (e.g., patellar, tibiofemoral) and the affected knee (left or right) were not specified in the original injury documentation. This is appropriate for follow-up care or when the sequela manifests long after the initial event.

• Always assign a "S" (sequela) seventh character for conditions that are late effects of an injury.
• This code should be used when documentation lacks specificity regarding the type of knee dislocation and laterality.
• Consider if more specific codes for knee sequelae (e.g., S83.11_S, S83.12_S) can be used if further details are available in the medical record.
