Breakdown (mechanical) of electronic bone stimulator, subs

This code signifies a mechanical malfunction or failure of an implanted electronic bone stimulator device. This breakdown is not due to infection or displacement, but rather an issue with the device's physical integrity or internal components. The encounter being coded is a follow-up visit after initial treatment for the breakdown.

This code is appropriate for subsequent encounters when a patient presents with symptoms or findings related to a previously identified mechanical failure of their electronic bone stimulator. Examples include follow-up appointments after an initial diagnosis of device breakdown, or visits for further evaluation and management of the mechanical issue. It should be used when the patient is still receiving care for the initial breakdown event.

• Ensure documentation clearly specifies a mechanical breakdown, not an infection or displacement.
• Verify the encounter is a "subsequent encounter" (D) for the breakdown, meaning the patient is still under active treatment for this specific complication.
• Always code the underlying reason for the bone stimulator implantation if still relevant to the patient's care.
