Part B Insider (Multispecialty) Coding Alert

Medicare Errors:

Practices Underbilled $1.3 Billion in 2013, CMS Report Shows

CERT results reveal that initial hospital care, chiropractic visits topped list of Part B errors last year.

If your practice’s collections rate was off by 10.5 percent, you’d be in big trouble, right? Well, that’s the 2013 Part B improper payment rate, based on information that CMS recently released, which also shows that medical practitioners left over $1 billion on the table by undercoding claims.

CMS’s new Comprehensive Error Rate Testing (CERT) results, which were released last month, show that chiropractic visits had far and away the most errors, totaling a 51.5 percent error rate in that specialty. Following behind were initial hospital care visits, which showed a 28.3 percent error rate, and lab tests, which were improperly billed 26.1 percent of the time.

Documentation: The majority of the errors that CMS found involved insufficient documentation, which comprised 56.8 percent of the incorrect payments. The next most common issues were medical necessity errors (26.6 percent), incorrect coding (13.7 percent) and no documentation (1.4 percent).

Downcoding: Not all errors involved upcoding, however. CMS actually found that $1.3 billion in coding errors were due to instances where practices reported lower codes than their documentation justified. This means that medical practitioners shorted themselves out of significant reimbursement last year.

Among the most often undercoded Part B services were kidney and urinary tract procedures, pacemaker implantations, outpatient hospital visits, established patient office visits, subsequent hospital care, and treatment of peripheral vascular disorders, the report notes.
