Unspecified fracture of left ischium, sequela

This code indicates a long-term complication or late effect stemming from an unspecified fracture of the left ischium. It signifies that the initial injury has healed, but the patient is experiencing residual problems directly attributable to that past fracture. These sequelae could include chronic pain, nonunion, malunion, or functional limitations.

Apply this code when documenting a patient encounter for a condition that is a direct consequence of a previously sustained, unspecified fracture of the left ischium, and the initial fracture itself is no longer acute. This is appropriate for follow-up visits addressing chronic issues related to the old injury, not for the initial treatment of the fracture.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M84.452A for malunion of left ischium).
• Ensure documentation clearly links the current condition to the past left ischial fracture.
• Do not use this code for initial or subsequent encounters while the fracture is still undergoing active treatment.
