Effective Monday, hospitals must submit two claims to Medicare whenever a surgical error is reported along with a covered service: one claim for covered services unrelated to the error and another no-pay claim with the error coded on it. The billing change and non-payment policy are effective for inpatient and outpatient claims submitted Oct. 5 or later for services delivered after Jan. 15, 2009. They pertain to surgical procedures involving the wrong patient, procedure or body part under a national coverage decision implemented by Medicare in January.
