Breakdown (mechanical) of int fix of vertebrae, sequela

This code signifies a mechanical failure of an internal fixation device, such as rods, screws, or plates, that was surgically implanted to stabilize the vertebrae. This breakdown is not an acute event but rather a long-term complication or sequela of the initial fixation.

Use this code when documenting a patient presenting with symptoms or findings directly attributable to the mechanical failure of a vertebral internal fixation device, and the encounter is for the management of this long-term complication. This includes cases where hardware has fractured, loosened, or migrated over time, requiring further intervention or monitoring.

• Always use this code as a secondary diagnosis, following the code for the underlying condition or reason for the encounter.
• Ensure documentation clearly specifies "mechanical breakdown" and "sequela" to support the use of this specific code.
• Do not use for acute complications or infections related to the device; those have separate, acute complication codes.
