Can anyone confirm my codes for the below procedure?

I am also confused, whether we need to pick up 35371?

PREOPERATIVE DIAGNOSIS: Ischemic right lower extremity with thrombosed right

ax-fem bypass graft.

POSTOPERATIVE DIAGNOSIS: Ischemic right lower extremity with thrombosed right

ax-fem bypass graft.

PROCEDURES:

1. Redo right groin exploration.

2. Thrombectomy, right common femoral artery.

3. Thrombectomy, right ax-fem bypass graft.

4. Angiogram, right ax-fem bypass graft.

5. Percutaneous transluminal angioplasty of the right ax-fem bypass graft

using a 7 mm x 200 mm balloon, completion angiogram.

6. Angiogram right lower extremity.

PROCEDURE IN DETAIL: Informed consent was obtained. The patient was brought

to the operating room and placed in supine position. Adequate anesthesia was

obtained using general endotracheal intubation. The patient was prepped and

draped in normal sterile fashion. Time-out was performed confirming the

patient, operative procedure, and location. His previous right groin incision

was opened up. Subcutaneous tissue was divided with electrocautery.

Dissection was carried down to the right common femoral artery. The distal

aspect of the right limb of the ax-fem bypass graft was isolated and encircled

with vessel loops. There was a lot of scar tissue requiring careful

dissection down along the both ends of the common femoral artery. The common

femoral artery appeared to be somewhat aneurysmal proximally at 2 cm in

length. His right SFA was chronically occluded and only had a few branches

going down the deep femoral artery. The patient was given a bolus of heparin

10,000 units IV and what appeared to be a bovine patch on top of the common

femoral artery. A longitudinal arteriotomy was made with an 11-blade scalpel,

extended with Potts scissors. The graft was completely occluded. Although

there had been flow on admission, 3 days ago there was no flow present.

Thrombectomy was then performed. There was excellent bleeding from a very

large side branch, which was somewhat medial in nature. This side branch

appeared to be 3 to 4 mm in dimension. This was occluded after placing of #3

embolectomy catheter and inflating it with a 3-way stopcock for hemostasis.

The embolectomy was then performed to the right ax-fem bypass graft. The

chronic clot was removed as well as some fresh clots. I used both the #5

embolectomy catheter and #4 embolectomy catheter as well as a 4 to 6 and 5 to

7 adherent clot catheters. I was able to get fairly good inflow present but

there appeared to be some residual pseudointima present. The graftotomy was

then closed using running 5-0 Prolene. After this, I could feel there was a

fairly strong Doppler signal to the graft. At this time, the common femoral

artery was cannulated with entry needle and guidewire was passed up the ax-fem

bypass graft and a 5-French sheath was placed. Bentson guidewire was passed

up to the axillary artery and followed by a 5-French Glide catheter.

Angiogram was then performed. This showed that the bypass graft was patent

but there appeared to be a moderate amount of residual pseudointima lining the

graft. Because of that, I decided to do the balloon angioplasty of the whole

graft. The balloon angioplasty was then performed with a 7 mm x 200 mm

balloon up to 10 atmospheres for 3 minutes in an overlapping fashion. This

was done and the patient had excellent outflow present. Angiogram was then

performed which did show branches of the deep femoral artery going distally

but these all appeared to be very small. The sheath was then removed,

hemostasis was achieved with a 5-0 Prolene. Wounds were irrigated out. A #19

round Blake drain was brought out the inferior aspect incision and sewn in

place with heavy nylon.
