Stress fracture, left fibula, sequela

This code signifies a long-term complication or late effect resulting from a stress fracture of the left fibula. It indicates that the patient is experiencing residual problems directly attributable to a previously healed or resolved stress fracture in this specific bone.

Apply this code when documentation clearly states a patient is presenting with a sequela (e.g., chronic pain, nonunion, malunion, functional limitation) directly related to a past stress fracture of the left fibula. The original stress fracture itself is no longer acute.

• Always sequence the sequela code first, followed by a code describing the specific nature of the sequela (e.g., M25.562 for chronic pain in the left ankle and foot).
• Ensure documentation explicitly links the current condition to a previous stress fracture, not an acute one.
• Verify laterality; this code is specific to the left fibula.
