Coxa magna, left hip

This code signifies an abnormally enlarged left femoral head, often resulting in an incongruent hip joint. This condition can lead to altered biomechanics, pain, and premature degenerative changes within the hip.

Apply this code when documentation explicitly states "coxa magna" affecting the left hip. This diagnosis is typically made based on radiographic findings demonstrating an increased size of the femoral head relative to the acetabulum.

• Ensure laterality is clearly documented as left.
• Do not confuse with coxa valga or coxa vara, which describe angulation deformities, not size.
• Look for associated conditions like osteoarthritis of the hip, which may require additional coding.
