Stress fracture, unspecified toe(s), sequela

This code signifies a stress fracture of an unspecified toe that is a long-term effect or complication of an earlier injury or condition. It indicates that the acute phase of the stress fracture has passed, and the patient is now experiencing residual problems directly attributable to that past fracture.

Apply this code when documentation clearly indicates a stress fracture of an unspecified toe as a sequela, meaning the patient is presenting for treatment of a chronic complication or late effect. This is appropriate for follow-up care related to the long-term consequences of the original stress fracture, such as persistent pain, deformity, or functional limitation.

• Requires documentation explicitly stating "sequela" or "late effect" of a stress fracture.
• Do not use for acute stress fractures; those are coded with M84.37- without the "S" seventh character.
• Always sequence this "S" code after the code(s) for the specific residual condition being treated.
