Hallux valgus (acquired)

This code represents an acquired deformity of the great toe where it deviates laterally towards the other toes, often accompanied by a medial prominence of the metatarsal head. This condition, commonly known as a bunion, can cause pain, inflammation, and difficulty with footwear.

Use this code when documentation clearly indicates a diagnosis of hallux valgus that is not congenital. This typically applies to adult patients presenting with symptoms such as pain, redness, or swelling at the base of the great toe, or visible lateral deviation. Supporting documentation includes physician notes detailing the acquired nature of the deformity and clinical findings.

• Ensure the documentation specifies "acquired" to differentiate from congenital forms.
• Do not confuse this with hallux rigidus, which is a degenerative arthritis of the great toe joint.
• Look for associated conditions like bunionette (tailor's bunion) or hammertoes, which may require additional codes.
