Stenosis of other cardiac prosth dev/grft, subs

This diagnosis code indicates a narrowing or obstruction of a previously implanted artificial cardiac device, such as a prosthetic valve, pacemaker lead, or vascular graft within the heart, that is not specified as a valve. This stenosis impairs the normal function of the device, potentially leading to reduced blood flow or electrical conduction issues.

Use this code when a patient presents for follow-up care, treatment, or management of stenosis affecting a non-valvular cardiac prosthetic device. This includes situations where the patient is receiving ongoing care for the complication, or during a subsequent admission for evaluation or intervention related to the stenosis.

• Ensure the documentation clearly specifies "stenosis" and identifies the affected device as a non-valvular cardiac prosthetic, implant, or graft.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use this code for stenosis of native cardiac structures or for initial encounters for this complication.
