Varus deformity, not elsewhere classified, left hip

This code describes an inward angulation of the left hip joint, where the distal part of the femur deviates medially relative to the proximal part. This deformity results in a decreased angle between the femoral neck and shaft, often leading to altered biomechanics and gait disturbances. It is a structural abnormality of the hip that is not classified under other specific conditions.

Use this code when documentation explicitly states a varus deformity of the left hip, and no more specific diagnosis (e.g., congenital coxa vara, post-traumatic varus) is identified. This code is appropriate for acquired or idiopathic varus deformities of the left hip. Supporting documentation should include physician notes detailing the physical examination findings, imaging reports (X-ray, MRI) confirming the varus angulation, and laterality.

• Ensure the documentation specifies "varus" deformity and not "valgus" deformity, which is an outward angulation.
• Verify the laterality is clearly documented as "left hip" to avoid coding errors.
• Do not use this code if a more specific diagnosis, such as congenital coxa vara (Q65.81), is documented, as this code is for deformities "not elsewhere classified."
