DOJ Allegations Illustrate Issues in Coding
Recent allegations by the Department of Justice (DOJ) against Kaiser Permanente (Kaiser) highlight some of the tensions in proper medical coding and in internal documentation review. DOJ recently intervened in a series of whistleblower lawsuits that alleged that internal chart reviews and amendment of medical records by Kaiser constituted improper upcoding of claims for Medicare Advantage beneficiaries. DOJ accused Kaiser of coercing its employees to retroactively change or add codes in order to increase reimbursement rates. Ultimately, DOJ claimed that the alleged upcoding resulted in an estimated 75% error rate.
DOJ alleged that Kaiser physicians changed medical records often months after care was provided in order to increase Medicare Advantage reimbursement. A whistleblower claimed that more than 50% of Kaiser physicians said that they were coerced to add diagnoses that they never considered, let alone evaluated or treated. Specifically, the lawsuit alleges that Kaiser targeted codes for atherosclerosis of the aorta as having a “high rate of reimbursement.” The whistleblower claimed that Kaiser told its facilities that 40% of their bonuses would be based on how often they coded atherosclerosis of the aorta, pointing to an email between executives that identified this upcoding as a “$40M opportunity.”
The lawsuit focuses on retroactive additions and changes to patients’ medical records. These retroactive changes are usually done during retrospective chart reviews, which are typically used promote proper coding and reimbursement for services performed. Although the practice of internally reviewing charts to identify and address documentation or coding issues is common and generally permissible, the changes should be supported by proper documentation and some documentation elements must be documented at the time of service. In this case, DOJ alleged that Kaiser’s changes were not supported by documentation and that Kaiser only performed retroactive chart reviews on patients that could receive risk-adjustment payments.
