Fibrosis due to cardiac prosth dev/grft, subs

This code signifies the development of fibrous tissue as a complication related to an implanted cardiac device, such as a pacemaker, defibrillator, artificial heart valve, or vascular graft. This fibrosis is a pathological response to the foreign material and can impair device function or surrounding tissue.

This code is appropriate for documenting follow-up care for a patient experiencing fibrosis around a cardiac prosthetic device. It should be used when the patient is receiving active treatment, monitoring, or evaluation for this specific complication after the initial treatment or during the healing phase.

• Requires a seventh character "D" for subsequent encounter, indicating ongoing care for the fibrosis.
• Always sequence this code after the primary diagnosis indicating the reason for the encounter (e.g., symptoms related to the fibrosis).
• Consider additional codes for specific symptoms or complications arising from the fibrosis (e.g., heart failure, device malfunction).
