Cardiology Coding Alert

Find out 2 ways the OIG says coders are making big mistakes

Now is not the time to be lax in how you report modifier 59. Carriers are still scrutinizing your separate and distinct service submissions. But you can prevent paybacks by avoiding the following pitfalls that will land your claims in the OIG's error rates.

Note: In a November 2005 study, the HHS Office of Inspector General cast a spotlight on the use of modifier 59 (Distinct procedural service), and the results weren't pretty. The OIG found a 40 percent error rate for modifier 59 in its claims sample. Confirm Separate Region Before Using 59 Pull a sample of your modifier 59 submissions and verify that those claims properly represent a distinct procedural service. Fifteen percent of the OIG's audited claims using modifier 59 had procedures that weren't distinct because "they were performed at the same session, same anatomical site, and/or through the same incision," says Daniel R. Levinson, inspector general, in "Use of Modifier 59 to Bypass Medicare's National Correct Coding Initiative Edits," an article posted on the OIG Web site www.oig.hhs.gov/oei/reports/oei-03-02-00771.pdf.

Example: If your cardiologist catheterizes the left and right common carotid arteries, you will report 36216 (Selective catheter placement, arterial system; initial second-order thoracic or brachiocephalic branch, within a vascular family) for the right common carotid (RCC) and 36215 (Selective catheter placement, arterial system; each first-order thoracic or brachiocephalic branch, within a vascular family) for the left common carotid (LCC). If you don't put modifier 59 on 36215, your payers will assume that both codes apply to the same vascular family.

Keep in mind: In cardiology, you'll find several situations in which you'll need modifier 59 to facilitate proper reimbursement that "seem to be in direct conflict with several generic modifier 59 rules-of-thumb," says Jim Collins, CPC, ACS-CA, CHCC, founder of The Cardiology Coalition in Matthews, N.C.

For instance, the National Correct Coding Initiative bundles "several diagnostic radiological supervision and interpretation codes into codes for interventional procedures. Cardiologists frequently perform these interventional procedures during the same operative session as the diagnostic study, through the same access site, and the same vessel." You can also apply this concept to both peripheral vascular and coronary procedures. Put 59 on the Secondary Code
 
Go back and reread the cath example above. See how you needed to attach modifier 59 to the secondary code (36215)? NCCI publishes a list of comprehensive/component "edits consisting of two codes (procedures) that cannot reasonably be performed together based on the code definitions or anatomic considerations," says Laurie Green, CPC, coding and compliance analyst at Group Health Cooperative in Seattle. "Each edit consists of a column-1 and column-2 code."

How bundles work: If a physician reports the two codes of [...]
