Stress fracture, left ankle, initial encounter for fracture

This code signifies a stress fracture affecting the left ankle, which is a hairline crack in the bone resulting from repetitive stress rather than a single traumatic event. It indicates that the patient is receiving initial active treatment for this specific fracture.

Apply this code when documentation confirms a stress fracture of the left ankle and the patient is in the acute phase of treatment, such as cast application, surgical repair, or initial follow-up care for the fracture itself. Supporting documentation includes imaging reports (X-ray, MRI) confirming the stress fracture and physician notes detailing the initial management plan.

• Ensure laterality is accurately documented (left ankle).
• Verify the encounter type is "initial" for active treatment; subsequent encounters will require a different seventh character.
• Differentiate from traumatic fractures; stress fractures typically lack a specific acute injury event.
