OIG: Physicians Generally Miscode POS
An Office of Inspector General (OIG) review suggests physicians correctly code the place of service (POS) in Medicare Part B claims only 10 percent of the time. This pattern of incorrectly coded claims for nonfacility services resulted in Medicare overpaying physicians an estimated $13.8 million in 2007, the OIG concludes in a July report.
Of the 100 services the OIG sampled, 90 of the services were coded as having been performed in a nonfacility location, when 60 of the services were actually performed in hospital outpatient departments and 30 were performed in ambulatory surgical centers (ASCs).
The OIG provides in the report this example of incorrect coding:
“A carrier paid a physician $374 for performing a spinal pain injection procedure coded as having been performed in his office. Our analysis showed that the physician actually performed this procedure in a hospital outpatient department and that a fiscal intermediary had reimbursed the hospital for the overhead portion of the service. If the claim had been coded correctly, the physician would have received a payment of $96, which would not have included overhead costs. As a result of the incorrect coding, the physician was overpaid $278.”
The OIG report recommends for the Centers for Medicare & Medicaid Services (CMS) to immediately reopen the claims associated with the 484,118 nonsampled services and work with the physicians who provided the services (and more than likely miscoded the POS) to recover any overpayments.
