Bunionette of unspecified foot

📋Clinical Description

This code describes a bunionette, also known as a tailor's bunion, which is a painful bony prominence on the outside of the fifth metatarsal head at the base of the little toe. It results from an enlargement or lateral deviation of the fifth metatarsal, causing irritation and inflammation.

🎯When to Use

Use this code when documentation indicates a bunionette without specifying laterality (left or right foot). This is appropriate when the medical record simply states "bunionette" or "tailor's bunion" without further detail on the affected foot.

💡Coding Tips

Always seek clarification from the provider if laterality is not documented to assign a more specific code (M21.621 for right, M21.622 for left).
Do not confuse with hallux valgus (bunion of the great toe), which is coded differently.
Consider additional codes for associated pain (e.g., M79.67- series) if documented.
