Other dislocation of unspecified patella, subs encntr

This code describes a subsequent encounter for a dislocation of the patella that is not specified as recurrent or traumatic, and the laterality (left or right) is also unspecified. It indicates that the patient is receiving follow-up care for a previously treated patellar dislocation.

Use this code for patients presenting for cast changes, physical therapy, medication management, or other ongoing treatment related to a patellar dislocation after the initial treatment has been rendered. It is appropriate when the specific cause of the dislocation (e.g., traumatic, recurrent) is not documented, and the affected knee is not specified.

• Requires a 7th character of 'D' for subsequent encounter.
• Ensure documentation supports follow-up care for a prior dislocation, not an initial injury.
• Avoid using this code if the laterality (left/right) or the nature of the dislocation (e.g., recurrent, traumatic) is clearly documented; more specific codes would then apply.
