Metatarsalgia, left foot

This code signifies pain in the metatarsal region of the left foot. It is a symptom, not a specific diagnosis, indicating inflammation or irritation of the metatarsal heads or surrounding structures.

Apply this code when documentation explicitly states metatarsalgia affecting the left foot. Supporting documentation should include a physical exam noting tenderness or pain in the metatarsal area of the left foot, often exacerbated by weight-bearing.

• Always specify laterality (left, right, or bilateral) when documented.
• Look for an underlying cause (e.g., bunion, hammertoe, stress fracture) and code it first if identified, as metatarsalgia is often a symptom.
• Avoid using this code if a more specific diagnosis for the left foot pain is established (e.g., M20.12 for hallux valgus of the left foot).
