Unspecified subluxation of right knee, initial encounter

This code signifies a partial dislocation of the right knee joint where the articular surfaces are no longer in proper alignment, but remain in partial contact. The specific bone or bones involved in the subluxation are not identified in the clinical documentation.

Apply this code when documentation indicates a right knee subluxation without further specificity regarding the affected structures (e.g., patella, tibia, femur). This is appropriate for the initial presentation and treatment of the injury.

• Requires documentation of "right knee" and "subluxation" without further detail.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• If the specific bone involved in the subluxation is known (e.g., patellar subluxation), a more specific code should be used.
