Stress fracture, right toe(s), sequela

This code signifies a stress fracture affecting one or more toes of the right foot, where the fracture itself is no longer acute but has resulted in a long-term complication or residual effect. This could include chronic pain, deformity, nonunion, or malunion directly attributable to the past stress fracture.

Apply this code when documentation clearly indicates a patient is presenting for treatment or evaluation of a residual condition directly resulting from a previously healed or resolved stress fracture of the right toe(s). The "sequela" designation implies that the acute phase of the fracture has passed, and the current encounter addresses a lasting consequence. Documentation must specify the right toe(s) and the sequela nature of the complaint.

• Ensure documentation explicitly states "sequela" or describes a chronic condition directly linked to a past stress fracture of the right toe(s).
• Do not use this code for an acute or current stress fracture; those would be coded with the appropriate M84.37- codes without the "S" seventh character.
• Always sequence this code after the primary diagnosis describing the specific sequela (e.g., chronic pain, deformity).
