Bunion of left foot

This code identifies a hallux valgus deformity affecting the left foot, characterized by a lateral deviation of the great toe and medial prominence of the first metatarsal head. This bony prominence, often inflamed, is commonly referred to as a bunion.

Apply this code when documentation explicitly states a bunion is present on the patient's left foot. Supporting documentation should include physical exam findings describing the deformity and laterality, often accompanied by patient complaints of pain or difficulty with footwear.

• Ensure laterality is clearly documented as "left foot" to avoid coding errors.
• Distinguish from bunionette (tailor's bunion) which affects the fifth metatarsal.
• Consider additional codes for associated conditions like hammertoe or metatarsalgia if documented.
