Calcaneal spur, left foot

This code signifies the presence of a bony outgrowth, or osteophyte, on the calcaneus (heel bone) of the patient's left foot. This spur typically forms on the plantar surface where the plantar fascia attaches, often causing localized pain and inflammation.

Use this code when documentation explicitly identifies a calcaneal spur affecting the left foot. Supporting documentation includes physician notes detailing physical examination findings, imaging reports (e.g., X-ray) confirming the spur's location, and patient complaints of left heel pain consistent with this diagnosis.

• Ensure laterality is clearly documented as "left foot" to avoid incorrect coding.
• Do not confuse with plantar fasciitis (M72.2), although the two conditions often coexist. Code both if documented.
• If the spur is bilateral, use the appropriate bilateral code (M77.30) or separate codes for each foot if specific laterality is not available for the bilateral code.
