Billing Vertebral Angiograms

Question:

Do I have to have the catheter is the vertebral artery to bill a vertebral angiogram?

Answer:

Not necessarily.  See the code descriptions below for vertebral imaging.  If the catheter is selectively placed in the subclavian or innominate artery and vertebral circulation is imaged and documented, code 36225 is reported. If the catheter is selectively placed in the vertebral artery and vertebral circulation is imaged and documented, code 36226 is reported.

CPT Code	Description	Vessels imaged
36225	Selective catheter placement, subclavian or innominate, unilateral	Ipsilateral vertebral circulation, including arch
36226	Selective catheter placement vertebral artery, unilateral	Ipsilateral vertebral circulation, including the arch

Coding Carotid Angiography

Question:

I performed a right common carotid artery catheterization with extracranial common carotid and intracranial imaging and left internal carotid catheterization with carotid circulation imaging. Can I report this as bilateral, 36224 and 36223-50?

Answer:

The bilateral modifier is only used for the exact same procedure/code performed bilaterally.

In your scenario the codes will be:

36224	for the left internal carotid catheterization with intracranial imaging, and
36223-59	for the right common carotid artery catheterization with extracranial and intracranial imaging

Coding Debridement for an Ulcer

Question:

I debrided and ulcer. How do I know if I use 97965 or 11042?

Answer:

Code 97597 is described by CPT as adebridement(e.g., high pressure waterjet with/without suction, sharp selective debridement with scissors, scalpel and forceps), open wound, (e.g., fibrin, devitalized epidermis and/or dermis, exudate, debris, biofilm), including topical application(s), wound assessment, use of a whirlpool, when performed and instruction(s) for ongoing care, per session, total wound(s) surface area; first 20 sq cm or less.By definition it is exclusively for selective debridement of the skin, epidermis and dermis.

In contrast, code 11042, is for a deeper selective debridement, one that includes the dermis, epidermis and subcutaneous tissue. The code description statesDebridement, subcutaneous tissue (includes epidermis and dermis, if performed); first 20 sq cm or less.

For any debridement make sure to document the depth of the tissue debrided, the location of the debridement and the size of the debridement. Other selective debridement codes (11043 and 11044) are also coded by the depth of tissue removed; muscle and/or fascia for 11043 and bone for 11044.

Moderate sedation Denials. How do we get paid for 99153?

Question:

We are billing the new moderate sedation codes, but are getting denied on the second 15 minutes, 99153.  Almost all our patients have sedation for more than 15 minutes. What are we doing wrong?

Answer:

You are doing nothing wrong!  The codes you are referencing are listed below.  Code 99151 or 99152 are paid without a problem.  It’s code 99153 that is the issue. When Medicare valued these new codes as part of the Medicare Physician Fee Schedule, 99152 (or G0500 for GI endoscopy procedures) had an RVU assigned.  Code 99153, for the second 15 minutes, (or a minimum of 23 minutes total of sedation) did not have a professional fee value assigned, indicating that Medicare will not pay for these additional minutes. Medicare considers all physician work for moderate sedation to be covered by the single code; 99151 (or G0500 for GI endoscopy procedures). Continue to bill per CPT guidelines that allow this second code. Private payors may pay for this code. Write off the Medicare denial.

CPT Code	Description
?99151	Moderate sedation services provided by the same physician or other qualified health care professional performing the diagnostic or therapeutic service that the sedation supports, requiring the presence of an independent trained observer to assist in the monitoring of the patient’s level of consciousness and physiological status; initial 15 minutes of intra-service time, patient younger than 5 years of age
?99152	initial 15 minutes of intra-service time, patient age 5 years or older
+99153	each additional 15 minutes intra-service time (List separately in addition to code for primary service)
G0500	Moderate sedation services provided by the same physician or other qualified health care professional performing a gastrointestinal endoscopic service that sedation supports, requiring the presence of an independent trained observer to assist in the monitoring of the patient’s level of consciousness and physiological status; initial 15 minutes of intra-service time, patient age 5 years or older. Report additional time with 99153 as appropriate Use only for GI endoscopy procedures for Medicare patients

Coding a Vena Cava Thrombectomy with a Urologist Co-Surgeon

Question:

A urologist asked me to clear the thrombus and repair the vena cava during a radical nephrectomy for tumor resection. What code should I use?

Answer:

In this case, you are acting as a co-surgeon on code 50230, nephrectomy, including partial ureterectomy, any open approach, including rib resection; radical with regional lymphadenectomy and/or vena cava thrombectomy. You will report 50230-62 and the urologist will also report 50230-62. Note that if either surgeon also performs a lymphadenectomy, that is also included in 50230.
