Bunionette of left foot

This code identifies a bunionette, also known as a tailor's bunion, affecting the left foot. This condition involves a painful bony prominence on the lateral aspect of the fifth metatarsal head, often caused by abnormal pressure or angulation of the fifth toe.

Apply this code when documentation explicitly states a diagnosis of "bunionette" or "tailor's bunion" located on the patient's left foot. Supporting documentation should include physical exam findings noting the lateral prominence and associated symptoms.

• Ensure laterality is clearly documented as "left foot" to avoid incorrect coding.
• Distinguish from hallux valgus (bunion of the great toe), which is coded differently.
• Look for associated conditions like bursitis or hammertoe, which may require additional codes.
