Fibrosis due to cardiac prosth dev/grft, initial encounter

This code signifies the development of fibrous tissue as a complication directly attributable to the presence of an artificial cardiac device, implant, or graft. This fibrosis can impair the function of the prosthetic and surrounding cardiac structures.

Apply this code when a patient presents with new or worsening symptoms, and diagnostic imaging or biopsy confirms the presence of fibrosis linked to a previously implanted cardiac prosthetic. This is appropriate for the initial evaluation and treatment of this specific complication.

• Ensure documentation clearly links the fibrosis to the cardiac prosthetic and specifies "initial encounter."
• Code any associated cardiac conditions or symptoms separately.
• Distinguish from infection or mechanical complications, which have different codes.
