Stress fracture, right fibula, sequela

This code signifies a stress fracture of the right fibula where the acute injury has healed, but the patient continues to experience residual effects or complications directly attributable to the original fracture. These sequelae might include chronic pain, stiffness, deformity, or functional limitations.

Apply this code when documentation clearly indicates that a patient is presenting for treatment or evaluation of a long-term complication or residual effect stemming from a previously healed stress fracture of the right fibula. The "S" seventh character is crucial and indicates that the current encounter is for the sequela of the fracture, not the active fracture itself.

• Ensure documentation explicitly states the encounter is for a sequela of the fracture, not an active or healing fracture.
• Do not use this code for initial treatment or routine follow-up of an active or healing stress fracture; use codes from the M84.363- series with appropriate 7th characters (A, D, G, P, K).
• Always sequence this code first if the sequela is the primary reason for the encounter, followed by codes for the specific manifestation of the sequela (e.g., chronic pain).
