Nearly 42% of Medicare claims for evaluation and management services are incorrectly coded, according to a recent report from the U.S. Department of Health and Human Services’ Office of the Inspector General.
Nearly 42% of Medicare claims for evaluation and management (E/M) services are incorrectly coded, according to a recent study from the U.S. Department of Health and Human Services’ Office of the Inspector General (OIG).
In its medical records review from 2010, the OIG report shows that Medicare inappropriately paid some $6.7 billion for incorrectly coded claims and those lacking proper documentation. That represents 21% of Medicare payments for E/M services in 2010.
The study found that incorrect coding included both upcoding and downcoding, and 19% of claims were lacking proper documentation. Claims for high-coding physicians were more likely to be incorrectly coded or insufficiently documented than claims from other physicians, the report says.
The report calls on Centers for Medicare and Medicaid Services (CMS) to educate physicians on coding and documentation requirements for E/M services, continue to encourage contractors to review E/M services billed for by high-coding physicians and follow-up on claims for E/M services that were paid in error.
In an opinion accompanying the report, CMS said it did not agree with the recommendation to encourage contractors to review E/M services billed by high-coding physicians, simply because it would cost the agency more to administer than it would collect. CMS says it will reassess the effectiveness of reviewing claims billed by high-coding physicians as it relates to other efforts like Comparative Billing Reports.
“We acknowledge that CMS must weigh the costs and benefits for reviewing claims for E/M services against doing so for more costly Part B services,” OIG adds.
But OIG is also calling on the agency to address coding problems associated with E/M services to “properly safeguard Medicare.” “Given the substantial spending on E/M services and the prevalence of error, CMS must use all of the tools at its disposal to more effectively identify and eliminate improper payments associated with E/M services,” the report says.
As part of the recommendation, education of physicians remains a critical component to improving coding practices. “CMS should educate physicians on the components used to determine the level of an E/M service and emphasize the documentation needed in the medical record to support that level, OIG says.
