Chapter 4 (p. 105) Surgery CARDIOVASCULAR Cardiovascular System Codes categorized by 1) body part involved 2) procedure performed Vascular Injection Procedures Intra-Arterial/Intra-Aortic Injections Intravenous Injections Inserting a Pacemaker (or Pulse Generator) or Pacing Cardioverter-Defibrillator (33202-33249) The pacemaker device is being inserted percutaneously and Leads are being attached transvenously (thru the circulatory system to get into the heart). Another way to attach leads is epicardially (upon the surface of the heart) which is usually not done locally unless it's an emergency situation. Single Chamber Devices: lead into the Rt atrium or Rt ventricle. The sinoatrial node and Bundle of His are located here. Need electrical stimulation to generate a pulse. Dual Chamber Devices: A lead into the Rt atrium and the Rt ventricle. Biventricular Devices: A lead into both ventricles. Crossing the coronary sinus (see pg. 189 picture). Used in pts with Congestive Heart Failure (CHF). If the Op Rpt talks about going through or crossing the coronary sinus, they are probably putting a lead to the left ventricle. A more involved procedure. When inserting Implantable cardioverter defibrillator devices you need to ask the following when coding: Was the electrode(s) inserted into the atrium, ventricle, ore both? Was a single lead inserted? Dual leads? Multiple leads? Did the procedure involve inserting, replacing, or repositioning the device(s)? Did the surgeon use the epicardial or transvenous approach? The Op Rpt may say after inserting a defibrillator that they've converted the pt out of V-Fib. This is intentional to test to see if the device is working. Do not code the V-Fib as a Dx if this is the only place it is mentioned. Page | 1 Coronary Artery Bypass Grafting (CABG) (For Physician Coding) Count the number of location on Coronary Artery being bypassed. 2 Techniques for bypass --Saphenous vein (or other vein) out of leg, reverse it to act as artery and connect it to the Aorta and then to the coronary artery. (33510-16) --Internal Mammary or Thoracic Arteries pulled forward. (33533-48) These are coded based on the number of anastemoses are being made with the graft(s). If doing BOTH arterial and venous bypass graft... code the arterial portion (33533-48) and then use ADDON code (33517-23) If doing venous graft only, these other 2 areas are excluded. Ex: We did a bypass: RT, internal mammary artery bypass, single. Also did an aortocoronary bypass with a saphenous vein, bypassing to LAD, and to the obtuse marginal vein (branch). 33533 + 33518 (2 locations) Harvesting of saphenous vein graft is included in the Venous and Combination code set. If vein comes from elsewhere (leg or upper extremities) (35500, 35572) Add-on codes for harvesting vessel for CABG. Know: Arterial and Venous? Venous only? Arterial only? Code vein graft if other than saphenous vein A redo on a CABG operation (> 1 month after the original) is coded +33530 (at the end of the combined A-V grafting codes. More complicated than the original procedure. Do not code the original procedure. Just the current CABG + redo codes. Bovine Arch: Aortic arch has only 2 major arteries coming off it instead of 3. This changes the order of the branches. Contralateral study: Opposite side. Go up from below to above the aorta, then come back down thru aorta. Ipsilateral study: Same side Chapter 4 (p. 105) Surgery CARDIOVASCULAR Page | 2 Interventional Radiology Procedures for Cardiovascular Conditions Imaging for remote access via catheters in order to do imaging exams to visualize blockages. = Minimum of 2 codes (See Appendix L for classification guidance of vascular families when coding injecting contrast into veins and arteries.) Arteriovenous Fistulas and Grafts Most desirable method for hemodialysis access less likely to clot less likely to become infected last longer The surgeon connects artery to vein. Arterial pressure toughens up the vein walls & they thicken. Good for dialysis needles. Angiography (2 codes) Imaging portion: Radiology. i.e., supervision and interpretation (S&I) of images These codes are assigned based on the vessels imaged, not the vessels catheterized. Use notes to see if CPT codes are bundled together w/S&I codes or not. Surgical portion: Inserting catheter i.e., injection Fistula: take longer to heal. Vein Transposition: coded according to vein used. May be donor vein or autologous Direct Anastomosis (Cimino): Side-by-side connection (36821) of contrast, implant of device, removal of stricture w/angioplasty balloon Imaging codes are often chargemaster driven (hosp) Catheterization part is more challenging: Know Catheter Placement Nonselective: The catheter is not advanced beyond the access site. a) the vascular catheter is left in the vessel it punctured and not advanced any further; or b) the vascular catheter is advanced into the aorta and not beyond; Selective: catheter placement is moved beyond the vessel punctured or beyond the aorta. a) Have to know that the catheter was placed into Aorta and moved past it and know where the catheter tip ended up. Arterial vascular family: arteries fed by a primary branch Venous vascular family: veins that flow into a primary branch Coding Guidelines instruct (p. 110) to code to the highest-order catheter placement within a vascular family (smallest branch); Each vascular family catheterized is coded separately (if catheter backed out and moved to another family); a code for nonselective catheter placement should not be assigned in addition to a selective catheter placement code unless there are multiple accesses (punctures). Graft: Harvesting vein (autogenic) If veins are too small or too far apart or not enough time to perform procedure for fistula, an AV Graft (36825-36830) may be performed. Advantage: Quicker to heal. Disadvantages: produce clots or become infected, may need revision(s). Complications of AV Fistulas & Grafts (p. 112) Clotting Obstruction Narrowing of the access Corrections of Grafts Stenosis: angioplasty, stent placement, thrombectomy Can do balloon angioplasty to enlarge (35476) Thrombectomy can be done with or w/out revision (open) (36831, 32, 33) Revisions: The fistula or graft may need fixing Percutaneous thrombectomy may be via pharmaceutical or mechanical (36870) o + punctures of Artery and Vein, each coded (36147, 36148) Venous anastomostic stenosis (are common) often treated with balloon angioplasties to restore patency and flow. (35476 Transluminal balloon angioplasty, percutaneous, venous) Chapter 4 (p. 105) Surgery CARDIOVASCULAR Central Venous Access Procedures CVAD - Central Venous Access Device for frequent access to bloodstream: Antibiotics, Chemotherapy Fluids & Nutritional compounds Tranfusion of blood products Multiple blood draws for testing Removals are usually done in physician office. Know: 1) Did catheter end in central vein? 2) Was access point central or peripheral? 3) Was catheter tunneled or not? 4) Is there a Pump or Port? 5) Age of Pt? Peripherally Inserted Central Catheter (PICC Line 36568) Ex: 5 yr old, central cath inserted thru cephalic vein, terminates in brachiocephalic (inominate) 1. central, peripherally inserted = 36569 Endovascular Revascularization (Open/Percutaneous, Transcatheter) (p. 115) Peripheral artery disease (PAD): Plaque builds up in arteries of limbs. Balloon angioplasty w/or w/out stents by site by procedures performed (stent in, or atherectomy -plaque out) Coding Guidelines include: Only 1 code from family reported for each lower extemity vessel--code to the highest severity, most intense thing being done. Tx of multiple territories in same leg, one primary low extremity coce is used for each territory treated. Use add-on codes for additional vessels treated w/in the territory If a lesion extends across the margins of one vessel vascular teritory to another but can be opened w/single therapy, the single code should be reported (overlapping stents across the blockage, this is stenting 1 vessel - single therapy) Page | 3 Primary: initial Secondary: It's been done before Ligation, Division, and Stripping of Saphenous Veins Varicose veins (37718-37735). If veins are cut out or tied off, there are collateral veins for circulation.
