Unspecified subluxation of left knee, sequela

This code signifies a long-term or late effect of an unstated subluxation (partial dislocation) of the left knee joint. It indicates that the patient is experiencing residual problems or complications directly attributable to a past, unspecified subluxation event, rather than the acute injury itself.

This code is appropriate when documenting conditions or symptoms that are a direct consequence of a previously sustained, but unspecified, subluxation of the left knee. It should be used for chronic pain, instability, or functional limitations that persist after the initial injury has resolved. Do not use for acute or current subluxations.

• Always sequence this code after the code for the specific sequela (e.g., chronic pain, instability).
• Ensure documentation clearly links the current condition to a prior, unspecified left knee subluxation.
• Avoid using this code if the original subluxation was specified or if the current condition is an acute injury.
