In-stent restenosis (ISR) is the narrowing of a stented coronary artery lesion. The mean time from percutaneous coronary intervention (PCI) to ISR was 12 months with drug-eluting stents (DES) and 6 months with bare metal stents (BMS). ISR typically presents as recurrent angina.
Restenosis means that a section of blocked artery that was opened up with angioplasty or a stent has become narrowed again. There are many treatment options for patients who have restenosis after receiving a stent.
The 2022 edition of ICD-10-CM I25. 84 became effective on October 1, 2021.
What Causes Restenosis? Restenosis is caused by an overgrowth of scar tissue. When a stent is first placed, healthy tissue from the lining of your cell walls grows inside of it. This is good because it keeps your blood from clotting as it flows through the stent.
Stent thrombosis is a thrombotic occlusion of a coronary stent. This is usually an acute process in contrast to restenosis, which is a gradual narrowing of the stent lumen due to neointimal proliferation. Stent thrombosis often results in an acute coronary syndrome, while restenosis often results in anginal symptoms.
IST usually causes sudden and severe symptoms. The clot usually blocks the entire coronary artery, so no blood can get to the part of the heart it supplies, causing a heart attack (myocardial infarction).
Answer: Assign code T82. 855A, Stenosis of coronary artery stent, initial encounter, for the “in-stent” restenosis and I25. 10, Atherosclerotic heart disease of native coronary artery without angina pectoris, for the CAD.
These arteries carry blood to the head, face, and brain. This narrowing is usually the result of a build-up of plaque within the arteries, a condition called atherosclerosis. Stenosis can worsen over time to completely block the artery which may lead to stroke.

Restenosis can be defined as a reduction in the luminal diameter of more than 50%. It had a high incidence rate of 25–50% in patients having undergone balloon angioplasty, with the vast majority of patients requiring revascularisation within 6 months (3).
Restenosis, a narrowing of blood vessels following angioplasty or stent placement is seen in up to 50% of patients. Cases are treated with various options, including drugs, mechanical devices such as stents, genetic treatment such as gene transfer or infusion of stem cells, and combinations of the above.
Use of targeted treatments to reduce neointimal hyperplasia and restenosis, which include:Drug-eluting stents.Perivascular delivery which delivers the drug into the space around the artery.Delivery catheters.Antibody or peptide-linked drugs.Gene-based therapies.Cell-based therapies.Nanoparticle-based drug delivery.
How do we treat restenosis? Repeat angioplasty or bypass surgery can be used to treat in-stent restenosis. In addition, local intravascular radiation (brachytherapy) can be used after treating in-stent restenosis with angioplasty to prevent reoccurrence.

Ellis says, “in-stent restenosis still occurs in approximately 3 to 10% of patients within six to nine months, and sometimes afterwards. We have learned that restenosis is a very complex process.” Some known causes include: Stents that are too small or misaligned in the blood vessel.
