Fibrous dysplasia (monostotic), right thigh

This code signifies a benign, localized bone disorder characterized by the replacement of normal bone with fibrous tissue and immature woven bone, specifically affecting a single bone in the right thigh. This condition can lead to bone weakness, pain, and deformity.

Use this code when documentation clearly indicates a diagnosis of monostotic fibrous dysplasia located in the right femur. This diagnosis is typically confirmed through imaging studies (X-ray, MRI) and sometimes biopsy.

• Ensure documentation specifies "monostotic" to differentiate from polyostotic forms.
• Verify the affected anatomical site is explicitly the "right thigh" (femur).
• Do not confuse with other bone dysplasias or benign bone tumors.
