Unspecified dislocation of left patella, initial encounter

This code signifies a left kneecap dislocation where the specific type of dislocation (e.g., lateral, medial, intra-articular) is not documented by the provider. It indicates the very first time this particular injury is being treated.

Apply this code when a patient presents with a dislocated left patella, and the medical record does not specify the direction or mechanism of the dislocation. It is appropriate for the initial evaluation and treatment of such an injury.

• Ensure "left" patella is explicitly documented; otherwise, an unspecified laterality code may be more appropriate.
• Confirm this is the patient's first encounter for this specific injury; subsequent encounters require a different seventh character.
• Avoid using this code if the medical record clearly specifies the type of patellar dislocation (e.g., lateral, medial).
