Breakdown of esophageal anti-reflux device, subs

This code signifies a mechanical failure or malfunction of an implanted device designed to prevent gastroesophageal reflux, specifically involving the esophagus. This breakdown can manifest as a structural defect, displacement, or other mechanical issue compromising the device's intended function.

Apply this code when a patient presents for follow-up care, evaluation, or treatment related to a previously diagnosed mechanical breakdown of an esophageal anti-reflux device. This includes encounters for assessment of symptoms, planning for revision surgery, or managing complications directly attributable to the device's mechanical failure after the initial treatment or diagnosis.

• Ensure documentation clearly specifies a mechanical breakdown of the device, not an infection or other non-mechanical complication.
• Verify that the encounter is a "subsequent encounter" (D) for the breakdown, meaning the initial treatment for the breakdown has already occurred.
• Pair this code with an external cause code if the breakdown was due to an external event, though mechanical failures are often spontaneous.
