Frequency of reporting 99214 and 99215 increased 17 percent over 9-year period. If you examine your practice's E/M trend line, does your frequency of reporting high-level E/M codes increase dramatically over the years? If so, you should determine the reasons why, before your MAC begins forcing you to make that determination. A recent OIG study found that physicians increased their billing of higher-level E/M codes across all categories (inpatient, outpatient, etc.) between 2001 and 2010. In fact, the OIG sent CMS a list of 1,700 physicians who were identified as "consistently billing higher-level E/M codes in 2010." The report results were summarized as follows by the OIG in its report, Coding Trends of Medicare Evaluation and Management Services, which was published on May 9. Outpatient: Inpatient: Emergency: These Specialties Did the Most Damage According to the OIG report, certain specialties seemed to report more high-level codes than others. Among the physicians who consistently billed the two highest-level E/M codes were internal medicine, family practice, emergency medicine, nurse practitioners, ob-gyns, and cardiologists. Specialties who billed the two highest-level E/M codes the least often were hematologists, cardiac and thoracic surgeons, surgical oncologists, pain management physicians, intensivists, hand surgeons, and allergists, among others. High-Level Codes Don't Necessarily Equal Fraud Many reasons exist that could cause a practice to legitimately begin coding more high-level E/M services than in the past. For instance, the practice may have begun seeing a more complex patient population who have more chronic problems that require intense management. Or the practice may have been audited and discovered the physicians were downcoding claims, so now the physicians are correctly coding based on the documentation, which warrants more 99214s and 99215s. If you fit into one of the legitimate billing categories such as these, you shouldn't fret the new OIG study. If, however, you aren't sure how your physicians arrive at their E/M codes, it's time to offer a quick education session at your practice. The OIG recommends coding education as the number one priority following the results of this report, and also encouraged MACs to review physicians' E/M billing patterns to avoid improper payments. "CMS should conduct additional reviews of physicians who consistently bill higher level E/M codes to ensure that their claims are appropriate," the OIG recommends.
