CMS shows which issues sidelined these practices. Almost 43 percent of the quality data codes (QDCs) that practices submitted to CMS were ineligible for the PQRI bonus because physicians reported them improperly,CMS noted in a February report, "Quality-Data Code Submissions Error Report." The report analyzed PQRI submissions over the first three quarters of 2008. For 2009, the PQRI incentive payment is two percent of your physician's allowed charges under the Medicare physician fee schedule. If you'd like to keep that two percent flowing into your practice, avoid these common errors CMS found: Missing NPI CMS notes that 97,131 of the QDC submissions were missing their national provider identifier (NPI). Among the worst offenders in this category were claims for measure 112 (Screening mammography), which lacked an NPI in 3.5 percent of QDCs. Wrong HCPCS Code A whopping 15.6 percent of QDC submissions (nearly 3 million claims) had incorrect HCPCS codes on them. One of the most common errors in this category occurred with measure 130 (Documentation of current medications). CMS noted that 74.6 percent of claims for this measure featured an incorrect HCPCS code. Also at a high risk of errors was measure 46 (Medication reconciliation), with 69 percent of claims featuring an incorrect HCPCS code. You don't want to face a double-whammy -- a denied claim and lost PQRI bonus money due to a wrong code, says Wrong Diagnosis CMS found that 14.9 percent of QDC submissions included incorrect diagnosis codes. A prime offender in this category was measure 40 (Management following fracture), which had incorrect diagnosis codes 84.3 percent of the time. Keep in mind: For instance, CMS showed a 12.8 percent error rate in patient-gender mismatches for measure 71 (Hormonal therapy for stage IC-III ER/PR positive breast cancer).
