With over $600 million paid improperly, physicians didnt document their subsequent hospital care well. If your favorite code is 99211, watch out. A new CMS report reveals that more than 15 percent of claims submitted to Part B for this code between Sept. 2006 and Sept. 2007 were missing critical documentation, causing Medicare to request more than $24 million back from providers. The comprehensive error rate testing (CERT) report found 99211 billed inappropriately in the insufficientdocumentation category. Meanwhile, the CMS report indicates that Medicare paid out nearly $39 million more than it should have for subsequent hospital care code 99232 in the no documentation error category. Its possible that doctors in the hospital tend to peek in on the patient and dont write a lot in the chart, notes Barbara J.Cobuzzi,MBA, CPC,CPC-H, CPC-P, CENTC, CHCC, senior coder and auditor for The Coding Network, and president of CRN Healthcare Solutions. The physician may write, Patient stable, or Patient a bit worse, order this exam, and although they may be examining the patient, they may not document it well enough, Cobuzzi says. Therefore, what Medicares reviewers may classify as upcoding may simply be your physician underdocumenting his charts. Plus: When it comes to overall error rates, CMS tagged consults with the highest outpatient error rate (16.6 percent), followed by new patient office visits (99201-99205), with a 15.5 percent error tally. I have done many audits and I do find that physicians often code new patient visits incorrectly, says Susan Vogelberger, CPC, CPC-H,CPC-I, CMBS, CCP-P, CEO of Healthcare Consulting & Coding Education, LLC. The key component requirements are different from the established patients in that you need three out of three of the key components and that often is the problem, Vogelberger says. They also tend to score lower in one of the key components and that pulls the code down. Turn the page for a breakdown of what the latest CERT report uncovered.
