Fibrosis due to cardiac prosth dev/grft, sequela

This code signifies the long-term or late-onset development of fibrous tissue as a complication stemming from the presence of an implanted cardiac device, such as a pacemaker, defibrillator, valve, or vascular graft. This fibrosis is a chronic sequela, meaning it's a condition that arises as a direct consequence of the initial device implantation.

Apply this code when documenting a patient presenting with symptoms or findings directly attributable to fibrotic changes around a previously implanted cardiac prosthetic. This would include conditions like constrictive pericarditis due to fibrosis around a device, or impaired device function secondary to surrounding scar tissue, after the initial healing phase has passed.

• Ensure documentation clearly links the fibrosis to the cardiac prosthetic and indicates it's a late effect.
• Always code the underlying condition or specific manifestation of the fibrosis (e.g., constrictive pericarditis) first, if applicable.
• This "S" encounter code is for sequelae, indicating treatment of the late effects of the complication.
