Hallux valgus (acquired), right foot

This code signifies an acquired lateral deviation of the great toe (hallux) with medial prominence of the first metatarsal head, specifically affecting the patient's right foot. This deformity often results in a bunion, pain, and difficulty with footwear.

Apply this code when documentation clearly indicates a diagnosis of hallux valgus on the right foot, acquired rather than congenital. Supporting documentation typically includes physician notes detailing physical examination findings, patient complaints of pain or deformity, and sometimes imaging reports confirming the anatomical changes.

• Ensure documentation specifies "acquired" hallux valgus; congenital forms are coded differently.
• Laterality is crucial; verify the right foot is explicitly documented.
• Do not confuse with hallux rigidus (M20.2-), which describes stiffness of the great toe joint.
