Fibrosis due to vascular prosth dev/grft, subs

This code signifies the development of fibrous tissue around or within a previously implanted vascular device, such as a stent, graft, or other prosthetic, following the initial placement. This fibrosis is a complication that can impair the function of the device or surrounding tissues.

Use this code for follow-up encounters where a patient is being treated for or monitored for fibrosis that has developed as a complication of a vascular prosthetic device. This applies to situations where the fibrosis is a known issue and the patient is not in the initial healing phase immediately after the device implantation.

• Requires an additional code to specify the type of vascular prosthetic device involved.
• Confirm that the encounter is for follow-up care, not the initial treatment of the fibrosis.
• Distinguish from other complications like infection or mechanical failure.
