Metatarsalgia, unspecified foot

This code signifies a general diagnosis of pain in the ball of the foot, specifically affecting the metatarsal heads, without further specification of the underlying cause or the specific foot involved. It indicates a symptom rather than a definitive etiology.

Apply this code when documentation clearly states "metatarsalgia" but does not specify the laterality (left or right foot) or the underlying cause (e.g., Morton's neuroma, stress fracture, bunion). It is appropriate for initial encounters or when a more specific diagnosis is pending or not yet determined.

• Avoid using this code if the laterality (left or right foot) is documented; instead, use M77.41 (right) or M77.42 (left).
• Always strive for a more specific diagnosis if available, as metatarsalgia is a symptom.
• Consider sequencing this code after a more definitive diagnosis if the metatarsalgia is a manifestation of another condition.
