Why have interventional cardiologists’ salaries ranked near the top compared to other specialties for the past decade?1 Is it the long hours under high stress using extreme skills to perform dangerous procedures? Yes, but there is more. Effective advocacy by the Society for Cardiovascular Angiography and Interventions (SCAI) and American College of Cardiology (ACC) has played a large role. This is the story.

CORONARY INTERVENTION CODES AND REIMBURSEMENT: 2 DECADES OF EFFECTIVE ADVOCACY

Medicare, enacted in 1965, based reimbursement for physician services on the actual charge on the current bill, the customary charge during the past year, or the local medical profession’s “prevailing” charge during the past year, whichever was lowest.2 This system was chaotic and confusing. In response, the Omnibus Budget Reconciliation Act of 1989 switched Medicare to the Resource-Based Relative Value Scale, which used the estimates by Hsaio et al of physician time and effort to assign relative value units (RVUs) to physician services.3

In 1991, the Centers for Medicare & Medicaid Services (CMS) convened a series of technical expert panels (TEPs) to refine the initial estimates by Hsaio et al of work for selected procedures, including percutaneous transluminal coronary angioplasty (PTCA). A representative of the SCAI/ACC convinced the TEP to increase reimbursement for PTCA from Hsaio et al’s estimate of 9.5 RVUs to 10.5 RVUs. The 20 million or so coronary angioplasty and stenting procedures performed in the United States since 1992 have all been reimbursed at a rate reflecting that one RVU increase granted by the TEP in 1991. Thus, this one instance of effective advocacy by the SCAI/ACC increased reimbursement for these 20 million coronary intervention procedures over the last 2 decades.

Then, in 1994, the STRESS4 and BENESTENT5 studies compared elective stenting to balloon angioplasty, and a randomized trial compared the then state-of-the-art Palmaz-Schatz (Johnson & Johnson, New Brunswick, NJ) and Gianturco-Roubin II stents (Cook Medical, Bloomington, IN).6 At the time, elective stenting was just starting; most stents were placed to bail out failed balloon angioplasty. In this milieu, a code for coronary stenting was developed. The expert panel that advised CMS on reimbursement estimated that the average stenting procedure required 120 minutes of physician time from the first injection of lidocaine to the last catheter being withdrawn (diagnostic catheterization not included), 45 minutes of preparation time before the procedure, and 60 minutes of physician work after the procedure, for a total physician work time of 225 minutes per coronary stenting case. Thus, interventionists have been paid for coronary stenting at a rate based on almost 4 hours of work per procedure for the past 17 years.

NEW CORONARY INTERVENTION CODES AND VALUES

For the past several years, CMS has attempted to curb Medicare expenditures by identifying and reducing payment for overpriced services. In 2011, CMS identified coronary stenting as possibly being overpriced and required that it be revalued. The value of a service depends on the time required to perform it and, to a lesser extent, the intensity of the work. The SCAI/ACC knew that invasive cardiologists were reimbursed for 4 hours of work per stent case since 1994 and that procedural times might have shortened since then. Thus, a revaluation could significantly decrease the RVUs paid for a coronary stenting procedure.

Interventional cardiologists were also keenly aware of problems with the existing coronary intervention codes (Table 1). Reimbursement for an emergency middle-of-the-night ST-elevation myocardial infarction (STEMI) stent procedure was the same as for elective stenting of a healthy patient at noon. Stenting of complex left anterior descending (LAD) bifurcation lesions requiring three stents was valued the same as stenting of a type A lesion requiring one short stent. The SCAI/ ACC experts decided that if interventional procedures were to be revalued, it was time to develop codes that recognized and reimbursed physicians for the extra work of performing complex coronary interventions.

The SCAI/ACC experts developed a new set of codes that describe interventional procedures with greater detail (Table 2) and gained their approval by the AMA Current Procedural Terminology (CPT) panel. The codes then had to be valued, which required several steps. The first step was a survey of practicing interventionists to estimate physician work and time required for each new coronary intervention code. Practicing cardiologists estimated the skin-to-skin time required for coronary stenting to be much less than the 1994 estimate of 2 hours; 45 minutes to be exact. Without the new codes, reimbursement for coronary stenting would likely have been reduced proportionately by more than 50%. Fortunately, the SCAI/ACC experts convinced the American Medical Association Relative Value Update Committee to recommend to CMS that the new complex coronary intervention codes be reimbursed at rates higher (by up to 25%) than simple coronary stenting. Overall, reimbursement for the family of coronary intervention procedures will decrease 18% to 20%, much less than the 50% that might have occurred without the new codes.

NEW CORONARY INTERVENTION CODES TO SOLVE OLD PROBLEMS

The new codes solve several long-standing problems. For a decade, interventionists have complained that they are not reimbursed for the intensity of STEMI PCI. Now, they are. The Resource-Based Relative Value Scale rates intensity using units of RVUs per minute of procedure time. The intensity of seeing patients in clinic rates .03, coronary bypass surgery rates .10, and emergency tracheostomy rates .26. Coronary intervention codes were previously rated at .10, but the new code for STEMI PCI has an intensity rating of .18. The intensity of other new coronary intervention codes has been raised to the .13 to .15 range. The extra work and stress involved with PCI of grafts and chronic total occlusions is now recognized, and reimbursement compared to simple stenting is higher by 10% and 25%, respectively. Furthermore, stenting preceded by atherectomy is now reimbursed at a higher rate (by 12%) than stenting alone. Previously, there was no differential.

The additional work of performing PCI on multiple branches of a single artery is now recognized with separate codes. CMS refuses to pay for these, and the SCAI/ACC are lobbying CMS to reverse this decision. The good news is that the CMS decision does not limit reimbursement because CMS bundled the value of the additional branch codes into payment for the base codes. The SCAI/ACC still recommends (and CMS agrees) that the additional branch codes be used because some private payers may choose to reimburse them.

SUMMARY

Effective advocacy by the SCAI/ACC optimized reimbursement for PCI procedures for the past 2 decades. When CMS required revaluation of the PCI codes, the SCAI/ACC developed a new set of PCI codes that allows for more accurate reimbursement for more complex codes, mitigating the inevitable decrease in reimbursement for the simplest PCI codes. Interventionists and coding personnel must become familiar not only with the new codes, but also with the complex coding policies listed in the CPT manual6 that govern the appropriate use of these new codes.
