Cardiology Coding Alert

For these add-on codes, you get a list of which codes you can NOT use as primary.

The AMA’s CPT® and RBRVS 2016 Annual Symposium offered insider insights into proper use of the new and revised codes for 2016.

In the “Interventional Radiology” session, AMA CPT® editorial panel member Katharine L. Krol, MD, FSIR, FACR, discussed how CPT® 2016 changes coding for intravascular ultrasound (IVUS), which saw four familiar codes replaced by two new codes.

Deletions: CPT® 2016 deleted +37250 and +37251 for noncoronary IVUS along with associated S&I codes 75945 and +75946.

Additions: In their place, you now use codes that combine IVUS with S&I:

• +37252, Intravascular ultrasound (noncoronary vessel) during diagnostic evaluation and/or therapeutic intervention, including radiological supervision and interpretation; initial noncoronary vessel (List separately in addition to code for primary procedure
• +37253, … each additional noncoronary vessel (List separately in addition to code for primary procedure).

Tip 1: Report These Codes Per Vessel, With 1 Exception

As the code descriptors indicate, you should use +37252 for the initial or only vessel involved. Then use one unit of +37253 to report each additional vessel.

Because you report these codes per vessel, you should include all IVUS done in a single vessel during the entire procedure in a single unit. Include taking the probe in and out; positioning it; and imaging before, during, and after, Krol said.

‘Per vessel’ exception: “If a lesion extends across the margins of one vessel into another, this should be reported with a single code despite imaging more than one vessel,” the CPT® guidelines state. Krol offered the example of thrombus that starts at the popliteal and runs up to the vena cava. You report the IVUS using just a single code in that case.

Tip 2: Keep IVUS Codes Off of IVC Filter Claims

Remember that both initial vessel code +37252 and additional vessel code +37253 are add-on codes. Consequently, you must report them in addition to a primary code.

CPT® does not provide a specific list of applicable primary codes, but possibilities include either diagnostic angiography or therapeutic intervention codes. Examples of relevant interventions include “stent or stent graft placement, angioplasty, atherectomy, embolization, thrombolysis, transcatheter biopsy,” according to CPT® guidelines.

Forbidden few: A few codes already present in CPT® include IVUS, so you should not report +37252 or +37253 in conjunction with those codes. Specifically, you should not report separate IVUS codes in addition to intravascular vena cava filter codes 37191, 37192, and 37193, or in addition to intravascular foreign body retrieval code 37197.

Tip 3: Watch for Included Catheterization

The IVUS codes do not include catheterization of the vessels, so you may report catheterization separately, Krol said. CPT® guidelines indicate, “Non-selective and/or selective vascular catheterization may be separately reportable (e.g., 36005-36248).”

Caution: Be sure you haven’t already captured the catheterization in another code you’re reporting, Krol warned. For example, some of the therapeutic codes include access, and if you report one of those codes, you would not report a second catheterization code for the IVUS.
