Architectural Distortion

Architectural distortion is frequently seen on breast imaging and biopsies. I've seen support for both R92.8 and N64.89. Which ICD-10 is most appropriate?

Is 33418 device specific?

"Plan was to place an AC pascal clip on the medial aspect of A3-P3. However, there was significant difficulty in advancing the clip through the intended orifice. Multiple different trajectories were attempted as well as attempting to cross with the clip elongated.

After a multi-disciplinary discussion (CT surgeon, interventional cardiology, structural imager), plan was made to attempt plugging of the orifice.

Successful plugging of the intended orifice on the medial aspect of A3-P3 with an 18 mm PFO occluder with improvement of the mitral regurgitation from severe to none."

Can we use 33418 in this situation?

93319, Congenital Diagnosis

Does code 93319 require a congenital diagnosis when billed with 93312, 93314, 93315, 93317?

Intra aortic Balloon assist

Can you bill insert CPT 33967 and 33968 on same DOS?

36251/36252 angiogram requirements

Patient was referred for diagnostic right renal angiography with pressure gradients and possible renal artery stent for fibromuscular dysplasia of renal artery, after having a CT scan showing "The right renal artery stents are widely patent even the 1 in the branch vessel. However there is a subtle abnormality just proximal to the most proximal right renal artery stent that could represent an underlying severe stenosis or web from FMD."

Per procedure report, "the catheter was placed in the abdominal aorta via right common femoral artery with injection. Patent arterial vessels without significant disease: abdominal aorta, left renal, left common iliac, right renal and right common iliac. The catheter was placed in right renal artery via right common femoral artery with hemodynamics. No pressure gradient on pull back from inferior branch of right renal artery into the aorta. No renal artery hypertension." What is the appropriate coding for this diagnostic case?

CT head with finding performed with CTA head

A CT head w/o and CTA head were ordered and performed at the same time for same reason for exam. If there is a finding in the CT head w/o, would it be appropriate to code for both?

Contrast Enhanced Mammography

What codes would you use for a contrast enhanced mammogram done in a hospital setting? We've seen advice to use the mammogram codes 77065/77066, G0279 and the Qxxxx for contrast plus 76499. Is this correct? How about 96374 for the injection?

33215 Documentation Question

The patient had a dual chamber ICD upgrade to a CRT-D. Alongside the documentation of the LV lead insertion, there is this additional documentation:

"We noticed that the atrial lead was pulled back, and therefore slack was added and two additional Ethibond sutures were utilized to tie down the sleeve of atrial lead. The leads were connected to a new pulse generator."

Is this enough to report 33215 reposition of previously implanted pm/defib lead?

3D Post-processing with Kyphoplasty & Vertebroplasty

Can 3D post-processing be coded with kyphoplasty and vertebroplasty procedures? Currently there are no NCCI edits. Would this be considered included “procedural guidance”?

Per the SIR, 3D post-processing “requires documentation of diagnostic uncertainty prior to initiation of the procedure as well as the subsequent imaging findings and their significance. Determining the best approach to a lesion is not diagnostic imaging; determining whether a lesion exists is.” Per the NCCI Policy Manual Chapter 9.D.15, 3D rendering shall not be reported for mapping sites of biopsies or needle placements. Would 3D post-processing be considered “mapping” for kyphoplasty or vertebroplasty since it is already known the vertebra needs treating?

If 3D post-processing can be reported, what type of documentation is required to support billing for this service? We are thinking if 3D is performed prior to intervention then yes, and if during or after then no since bundled, but there are differences in opinion between physician and coders on this and we are seeking clarification.

Pleural effusion diagnosis sequencing

When a cancer patient has non-malignant pleural effusion and the fluid has not been sent off for any testing, would the first listed diagnosis be J90 followed by the cancer code? We know that when it is a malignant effusion the cancer is coded first, but we're unsure on the sequencing when the fluid is non-malignant.

non selective additional 37185 pulmonary

Does the catheter have to be moved to add 37185? Say they catheterize the RLL pulmonary artery (36015-RT), then they perform 37184-RT, then he says persistent defect noted in the right main PA on angio and performs thrombectomy on the right main PA without mentioning catheter movement? Can 37185 be added?

Also, is it considered pullback if after the right side procedure then he selects the LLL PA (36015) and does thrombectomy 37184-LT, then he states he slightly retracts the flowtriever to the Left Main PA & another aspiration is performed (37185-LT)? is that 36015-59LT again or 36014-? What would the cath placements codes also be?

Pre op Carotid stent placement (carotid body tumor resection planned)

A stent was placed in the left internal carotid/common carotid artery bifurcation to allow for reinforcement of the internal carotid artery as a means of protection at the time of planned future surgical resection of the tumor. The artery is normal without evidence of ulceration or stenosis. Which stent CPT code is most appropriate: 37216, 61626, or an unlisted code? 

Are assistant surgeons billable during Watchman procedure?

We have conflicting information on whether an assistant surgeon is allowed during a Watchman procedure. Encoder pro says that only 62 modifier is allowed. However, Codify says 62, 80, and 82 are allowed.

36556

We have a surgeon who places right femoral trialysis catheters, but he does not confirm where the tip of the catheter terminates. When I asked him he said post-op placement imaging for femoral catheters is not needed; he said there is no way to definitively confirm catheter placement in the iliac vein on plain film without cross-sectional imaging like a CT/MRI. In these cases do we report code 36556-52?

Lymphatic Malformation sclerotherapy: 37241 or 61626

I think I'm getting myself confuse with code 37241 and 61626.

Is 61626 more appropriate for this procedure? CPT instructions state, for non-CNS and non-head and neck embolization, see 37241-37244. Is neck lymphatic malformation a non-CNS and therefore 61626 should be used instead of 37241?

"TECHNIQUE: Right face and neck were prepped and draped in sterile fashion. Ultrasound was used to evaluate the lymphatic malformation and access into the malformation was obtained using a 21 gauge needle. Contrast injection venography confirmed location. Sclerotherapy was performed under fluoroscopic guidance. Three additional sites were selected and again access into the malformation was performed using a 21 gauge needle under ultrasound guidance. Location was confirmed with contrast injection. Sclerotherapy was performed under fluoroscopic guidance.

SCLEROSANT: Doxycycline 100 mg (4 mL) diluted in 1:1 ratio of Omnipaque and Bupivacaine for a final concentration of 25 mg/mL."

EV-ICD Relocation

Patient with an EV-ICD presents for relocation and DFT testing. The EV-ICD was relocated to a sub serratus position. "Further dissection was performed to achieve space in the sub serratus position where the generator was relocated to. Positioning was confirmed on lateral fluoroscopy and was also more posterior than the original placement." DFT testing was also performed. Please advise on appropriate coding for this case. Would you suggest an unlisted?

Albumin infusion with paracentesis

Have there been any updates to not being allowed to code albumin infusions (96365) with a paracentesis (49083)?

Angina with MI

In coding clinic 1st quarter 2024, there was a question and answer for angina with MI. "Assign code I21.4, Non-ST elevation (NSTEMI) myocardial infarction, as the principal diagnosis. Assign code I25.10, Atherosclerotic heart disease of native coronary artery without angina pectoris, for the multi-vessel native CAD, as an additional diagnosis. It would be inappropriate to assign a code for angina in the setting of an MI." Can you explain why we would not code angina with a MI? This seems like new guidance. In the Coding Guidelines 1.C.9 Atherosclerotic Coronary Artery Disease and Angina it mentions "If a patient with coronary artery disease is admitted due to an acute myocardial infarction (AMI), the AMI should be sequenced before the coronary artery disease." but does not mention anything about angina with the CAD in this statement. What are your thoughts on angina with MI?

61626 vs 37243

Patient with thymic tumor. Successful particle embolization of the right superior thyroid artery feeding the thymic tumor. Would you report code 37243 since the tumor is in the thymus or 61626 because the feeding artery is in the neck?

Documentation for Coronary IVUS

A patient undergoes coronary IVUS in the cath lab. The physician states in his report, “IVUS was used for stent sizing.” No additional information is provided (other than identification of the specific artery evaluated). Is this sufficient documentation to support coding the IVUS?

93571-52

If a patient in the cath lab is undergoing FFR and has an allergic reaction to the adenosine, prompting the procedure to be terminated, would it be appropriate for the hospital to report 93571-52?

93623 during EPS study

Can 93623 be coded based on the following? 

"The completeness of the lines were verified both with a Lasso catheter as well as well as exit block from inside the isolated areas before and after adenosine infusion. No arrhythmias were induced with burst pacing from the cs catheter."

3D with spinal reformatting

My question is assuming a CT chest, abdomen, and pelvis is performed with contrast (for professional billing). Provider documented: "3D multi-planar volumetric acquisition is obtained of the chest, abdomen and pelvis. Spinal reformatted imaging IS performed for the thoracic and lumbar spine." How would this be coded? In the same situation, if spinal reformatted imaging is NOT performed, how would this be coded?

61645 and 76380

I am hoping you can help us with Dyna CT 76380 being performed after a 61645 thrombectomy, n. I have been taught that if done after the intervention it is a follow up and it would bundle with the intervention. There is a edit with 61645 and 76380. Our neurosurgeon's feel it should be charged where it is not a required part of the procedure, and they are looking for intercranial hemorrhage after the thrombectomy . I am not seeing any old questions from DR Z Website addressing this and I am hoping you could give us your thoughts and opinion on this. I told the neurosurgeon I would reach out to you on this. Would the Dyna CT be separately reportable if performed after the intervention when the physician is looking for an intercranial hemorrhage after completing this procedure? I appreciate all your help on this question. Thank you DR Z I appreciate any help on this.

IVC Mass Percutaneous biopsy

"With the patient prone the back was prepped and draped sterilely. Local anesthesia with lidocaine. 17-18-gauge coaxial biopsy system advanced to the margin of the inferior vena cava from retroperitoneal posterior approach. When needle was seen to be in satisfactory position three core specimens were obtained. Impression: Percutaneous CT-guided biopsy of intravascular inferior vena cava mass." 

77012 for the guidance and what is the appropriate CPT code for the biopsy?

Professional Billing-Px Log When Embedded/Attested In MDs Final Report

Are PB coders able to use the embedded/included (not separate) procedure log to identify cath placements etc when 1) the physician includes the detailed procedure log in the final report, 2) Signs: Procedure Log and Final Result signed by John Doe, MD on 12/xx/24 at 1622 CST with corresponding Certification: I certify that I was present for catheter insertion, catheter manipulation, angiography, and angiographic interpretation of this patient, 3) and also notes: The procedure log was documented by Sally Smith listed and verified by John Doe, MD. The final report has all other required headers, signatures and procedure elements..OR..Does the physician need to add and dictate a special "Access" and "Technique" section in the same note to restate the access/technique details that are already stated in the embedded/included procedure log with supporting signatures as noted above? This qx was emailed to the ACC who supported the use of px log as noted above concluding: "in this location it is potentially all one connected flowing document."

LVEDP unable to be measured due to equipment malfunction.

Patient is brought in for a left heart catheterization with coronary angiography. Procedure is performed to completion with the exception of measurement and documentation of the LVEDP. The left ventricle was entered; however, equipment malfunction prevented the physician from obtaining the LVEDP. Can this be coded with 93458? Or am I allowed to code only for the coronary angiography, 93454? If 93458 is appropriate, what, if any, modifier would be appended? -52 says without anesthesia.

92972 denied with C9600-C9608 series.

We are coding 92972 with the C9600-C9608 series when drug eluted stenting takes place for the facility side. We are getting denied indicating C9600-C9608 is not a primary base code. Should we switch these to 92920-92944 series?

EPICARDIAL MICRA with Epicardial LV lead

I have a case that a NICU baby has had bipolar epicardial left ventricular lead and an epicardial generator Micra placed in anterior abdominal quadrant. Is this still 33274 / 33225??

"3 cm left anterior thoracotomy was performed, a bipolar ventricular lead was adhered to the left ventricle, tested with appropriate thresholds. We selected the Micra generator to avoid the previous infected sites. Generator was connected and final testing was completed without issue."

I'm really not sure if the Micra even has the ability to have a lead connected. Any direction on this is greatly appreciated.

Bentall plus aortic root replacement for a dissection

When a Bentall is performed, does this include an aortic root replacement?

 "The tear originated in the arch and extended between innominate and left carotid artery. The tear was completely resected, and a hemiarch was performed using a 23 mm x On-X valve conduit. Distal anastomosis was sewn using 4-0 prolene using double layers of felt pledgets. The root was reconstructed using interrupted 2-0 ethibond sutures, and coronary reimplantation was performed using 6-0 prolene sutures." 

Would this just be reported with code 33863, or would we also code an aortic graft?

92972 intravascular Lithotripsy

Our physician did a distal right coronary artery intravascular lithotripsy and InStent restenosis of the proximal right coronary artery. How many times should I report code 92972?

35371 & 35302

"Incision was placed in the left groin and taken down through subcutaneous tissue. We then carefully dissected the common femoral, the superficial femoral, and profunda femoris. The lateral circumflex femoral vein was doubly ligated and divided. I then dissected distally on the profunda, and two large terminal branches were circumferentially controlled. The patient was given full heparinization. At this point, we performed an arteriotomy in the common femoral. This was extended to the profunda all the way to the distal terminal branches. We then performed an endarterectomy on the common femoral and profunda and extensive eversion endarterectomy of the superficial femoral. I had to make a counterincision to get the plaque out of the proximal superficial femoral artery. After this was done, the shards of intima and media were circumferentially removed. A bovine pericardial patch was then placed on the common femoral to the distal profunda. This was sutured with 6-0 Prolene."

Does the counter incision mean that both codes 35371 and 35302 are billable?

33572 used for PDA, PL1 and diagonal branches

Per the CPT Codebook, Code 33572 (coronary endarterectomy) can only be used for LAD, circumflex, or RCA. The provider stated, "The PDA and PL1 are the only major branches of the RCA, and so these qualify as part of the RCA, and the diagonal is the major branch of the LAD and is part of the LAD distribution. As such, endarterectomy of this vessel qualifies as part of  the LAD". Endarterectomy of other coronary arteries is not reported separately per Encoder. Please advise.

Infected left axillary artery Dacron graft conduit stump 35905 w 35572?

"Excision of the infected axillary Dacron graft. The axillary artery was exposed proximally and distally to the graft anastomosis. Once branch was ligated using silk ties and clips. Infected axillary Dacron graft. We decided to use a bovine pericardial patch for axillary artery repair. IV heparin weight-based was administered and ACT was allowed to come above 250. The axillary artery was clamped proximally and distally using clamps. Sidebranches were clamped using Vesseloops. 11 blade was used to transect the graft off of the axillary artery right at the suture line. The graft was sent to microbiology. We then debrided the vessel wall back to healthy tissues. Inflow and outflow was confirmed. We then washed the wound with 3 L of normal saline via cystoscopy tubing. A bovine pericardial patch was then trimmed to shape and length and sewn onto the axillary artery using a running 6-0 Prolene suture. Prior to completion flush was done." 

35905 & 35572 or only 35905?

Bilateral Pulmonary Angiogram

If a bilateral pulmonary angiogram is performed from the MAIN pulmonary artery, then advanced selectively into the left and right segmental/subsegmental arteries with additional imaging, would that be coded as 75743 without additional imaging codes 75774?

Cervical Selective Nerve Root Injection

Can we report code 64479 for the cervical selective nerve root injection when the injection was onto the nerve root sleeve? Should the epidural space drug distribution be documented?

"The needle was advanced into the inferior posterior aspect of the C6/7 neural foramen. 0.5 cc of Omnipaque dye was then injected, and spread of dye was demonstrated to be along the nerve root sleeve. 2 cc 0.25% bupivacaine was injected onto to nerve root sleeve."

Is 93657 billable- Pulmonary vein isolation was performed

Aided by CARTO 3 mapping system & ICE wide area circumferential ablation was performed around antrum of both LT &RT PVs(WACAs) Lesions were delivered @ 45W for F' goal 400-450 & 500-550 on posterior & anterior walls, respectively. LT vein isolation was achieved on first pass. Breakthrough were noted in RT PVs, which required reinforcement lesions along WACA & lesions in RT carina area, forming a carinal line. post-ablation voltage map also confirmed presence of ablation related scar along wide area antral lesion set without any evidence of residual viable myocardial tissue. Adenosine showed no evidence of inducible reconnection Burst pacing from CS resulted in induction of an SVT that quickly degenerated into AFIB, which later self-terminated Given abnormal PW voltage & inducible AF, posterior wall isolation was pursued. Ablation lesions were incorpoated in posterior box with roof line & floor line connecting posterior aspects of LT & RT WACA lesions around pulmonary veins.Additional lesions were applied in posterior box @site epicardial breakthroug

36833 vs 37799

Physician requested 37799 and 36831 for thrombectomy of AVG that was ultimately excised.

"1 month s/p a left AV graft that initially had a good thrill but in post op visit was noted to thrombus"

"I made a transverse incision along the course of the graft. I placed a 3, 4, and 6 Fogarty through the outflow of the graft. I was able to get excellent back bleeding. I then attempted to pass a fogarty through the arterial anastomosis into the brachial artery. I was able to get some forward bleeding but was not significant enough to support a graft.

I thus decided that the graft was not salvageable and resected the exposed portion.

The wound was irrigated and closed in layers. . The patient tolerated the procedure well and went to recovery room in stable condition for later discharge home the same day.

Would both codes be appropriate? or would this just be an unlisted code for excision of graft without infection?

ALCOHOL AND MICROWAVE ABLATION ON SAME LIVER LESION

I know that we can bill two different ablation codes when performed on two separate/distinct lesions within the liver, but what about when they perform 2 different ablation types on the SAME lesion in the liver? Can we code both the alcohol and the microwave ablation or just the microwave?

IMPRESSION:

1) Successful ethanol ablation of the hepatic segment 4A metastatic mass using CT fluoroscopic guidance as described above.

2) Successful microwave ablation of the hepatic segment 4A metastatic mass using CT fluoroscopic guidance as described above.

Common/Cervical Carotid Thrombectomy and Stent for Occlusion

The provider is doing thrombectomy and stent placement with emboshield in the left common carotid artery to the cervical internal carotid artery for occlusion as patient had a stroke. There is no mention of stenosis at all. I am thinking 37184 and 37799 but greatly need you help to know what would be correct. I believe cath placement would be included in 37799, if that is correct (it was femoral approach). Thank you!!!

X modifier question

For diagnostic angiograms (that meet requirements to code with interventions) we use XU on the diagnostic angiograms. For cases when it's diagnostic angiograms only, we use XS on the additional of the same code (75726, 75726-XS) for separate vascular family.

If both of these uses apply to a case, would coding 75726-XU, 75726-XU-XS be appropriate?

Aortic root aneurysmorrhaphy repair & ascending aortic wrap

I have search everything I can find but have only found CPT code 33852 which seems to be partially correct or should I use the misc code 33999 CPT code for the following procedure. Please help. Sternotomy was performed; Aortic valve & root were inspected via TEE; Eccentric jet of mild AI noncoronary & right coronary leaflets; Aortic root was wrapped down to a 3cm size this reduced the AI down & all leaflets were moving well; chest tube & blake drains were placed. There is no mention of clamping or cardiopulmonary bypass. Thank you for your assistance

Can 33265 and 33269 be codded together here if 2 incision?

Convergent cannula was placed.VATS camera was then inserted. ablation of the posterior left atrial wall. convergent epi-sense system was then placed adjacent to the right superior pulmonary vein and suction was applied to the posterior left atrial wall. right inferior portion of the atrial wall and each ablation line was completed and carried laterally to the left-sided pulmonary veins. A total of 15 ablations to the left atrial wall were completed. a small pericardiotomy was created posterior to the phrenic nerve.The ligament of Marshall was then transected using the harmonic scalpel. The base of the left atrial appendage was approximately 40 mm. 40 mm clip was then placed over the appendage and positioned at the base and closed. TEE guidance, this confirmed full closure of the appendage. The clip was then released and the delivery device was removed.

Diagnosis help

If a patient has high blood pressure controlled by medication. Can you still use I10 ICD10 code as the diagnosis since while on the medication technically it’s no longer “high” blood pressure.

Genicular Artery Embolization from Pedal Access

I have a physician who is performing embolization of the genicular artery - however he is coming from a pedal access: **Vascular access - left dorsalis pedis - advanced to the left SFA, advanced to the left descending genicular artery branch, advanced to the left inferior medial genicular artery branch, advanced to the left superior medial genicular artery branch. Left superior medial artery genicular artery branch was embolized. Are we able to report 36245-36247 from this approach or 36140 until he reaches the aorta. Thanks!

Attempted Brachial Thrombectomies

How would you code this? Thank you!

Staples from a thrombectomy one month prior were removed. Sharp dissection was performed to identify an atretic brachial artery and two old bypasses in this scarred operative field. The cadaveric vein was opened however it was chronically occluded and thus unable to pass a Fogarty. Adjacent to a brachial vein, a small brachial artery was identified. Heparin was given. A transverse arteriotomy was made with an #11 blade. By passing a #2 fogarty, both inflow and outflow was established however no thrombus was noted. This was closed with interrupted 6-0 prolene sutures. Despite a multiphasic doppler signal on this vessel, its size remained diminutive and thus not adequate to perfuse his hand.

On the medial forearm another bypass was noted with mixed echogenicity contents. A separate incision was made. A vein bypass was noted. This too was occluded with subacute to chronic contents and neither Inflow nor outflow was established.

bilateral superior rectal artery embolization cpt code

catheter was used to subselect the origin of the inferior mesenteric artery. Next, with the help of a true form wire, a 2.9 merit microcatheter was now advanced into the inferior mesenteric artery used to subselect the left colic artery and further into the sigmoid artery. A sigmoid artery angiogram was now performed which demonstrates multiple superior rectal branches that extend towards the anal rectal region specifically supplying the hemorrhoids.

At this point, the 2.9 merit microcatheter is used to subselect a single left-sided and 3 right-sided superior rectal arteries where a total of six 3 mm coils are deposited. On the right side, a decision is made to embolize with particles. A standard 700 to 900 µm Embosphere particle mixture is made with 10 cc of contrast. A total of 2 cc is used to embolize the right superior rectal arteries at the very distal aspect of the superior rectal arteries in order to allow for distal embolization

do we use cpt 37242 for this & what cpt is simoid angio? Pls help

When is 35860 separately reportable?

"The patient underwent common femoral endarterectomy and left SFA to posterior tibial artery bypass graft earlier in the day. Patient now presents back in the OR later that day for lower extremity revascularization due to an acutely thrombosed bypass graft. LLE angiogram was performed. The left groin, thigh, and calf incisions were reopened and explored. Hematoma was evacuated from all three. Hemorrhage from the suture line of the proximal SFA anastomosis was controlled with Prolene suture. As it appeared there was adequate inflow in the superficial femoral artery and adequate outflow in the native posterior tibial artery. It was concluded based on imaging that the issue with the bypass was of conduit quality, and therefore a decision was made to revise the bypass by replacing the conduit."

The provider wants to report code 35860 in addition to the bypass graft revision code (for the exploration and evacuation of hematomas). Would this be considered bundled with the revision code? Or is it separately reportable with a -78 modifier?

MODIFIER 76 AND 77 REPEAT EKG DIFFERENT DAY SAME PHYSICIAN

New to Cardio coding. Please advise which modifier to use...

EKG done 12/4/23 then repeated on 12/8/23 by the same doctor. Would it be 93010 for DOS 12/4/23 then 93010- 77 - 1 DOS 12/8/23???

I understand that if repeated on same day then bill first line as 93010 - 1 then second line would be 93010-76 - 1 but I'm not sure about billing for the different DOS.... Please help... Thank you.

Native vs Graft Diagnosis

During diagnostic angiography of the coronary arteries and grafts for indication of angina, the IMA graft to the 2nd Diagonal branch is injected and visualized. A stenotic lesion is noted at the anastomosis of the IMA to the D2. Would this lesion be coded as atherosclerosis of the graft I25.729, or as native atherosclerosis I25.119?
