Other dislocation of unspecified knee, initial encounter

This code signifies a dislocation of the knee joint that is not further specified as a subluxation or other specific type, and the exact knee (left or right) is not documented. It indicates an acute injury where the bones forming the knee joint have become completely displaced from their normal alignment.

This code is appropriate for initial encounters with patients presenting with a knee dislocation where the specific type (e.g., patellar, tibiofemoral) or laterality is not yet determined or documented. It is used when the physician's documentation confirms a complete displacement of the knee joint components but lacks further detail.

• Ensure documentation clearly states "dislocation" and not "subluxation" for accurate code assignment.
• Only use this code if laterality (left/right) is truly unspecified in the medical record. If laterality is known, a more specific code should be used.
• The "A" suffix indicates an initial encounter for active treatment of the injury. Subsequent encounters will require different seventh characters.
