Other acquired deformities of knee

This code represents various non-congenital structural abnormalities or changes in the shape or alignment of the knee joint. These deformities are not present at birth but develop over time due to injury, disease, or other external factors, affecting the normal function and biomechanics of the knee.

Use this code for documented acquired knee deformities such as genu valgum (knock-knee), genu varum (bowleg), or other unspecified acquired angulation or rotational deformities of the knee. Documentation should clearly state the acquired nature of the deformity and its specific location within the knee.

• Differentiate from congenital knee deformities (755.60-755.69) and current traumatic injuries (e.g., fractures, dislocations).
• Ensure documentation specifies "acquired" or provides a clear etiology indicating a non-congenital origin.
• Consider additional codes for underlying causes (e.g., arthritis, osteomyelitis) if applicable and clearly documented.
