Pathological fracture, unsp foot, subs for fx w delay heal

This code signifies a fracture of an unspecified foot bone that occurred due to an underlying disease process, rather than trauma. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing.

Apply this code when documentation indicates a pathological fracture of the foot that is not healing at the expected rate. This code is appropriate for follow-up encounters after initial treatment, where delayed healing is the primary concern. Ensure the medical record clearly states the fracture is pathological and that healing is prolonged.

• Always sequence this code after the underlying disease causing the pathological fracture.
• Do not use this code for traumatic fractures; those require codes from the S92 category.
• Verify documentation specifies "unspecified foot" and "delayed healing" to support this specific code.
