CDIP Domain 4 CDI Metrics And Statistics Practice Test

Documentation gaps reduce the capture of diagnoses that drive Risk of Mortality and Severity of Illness. ROM and SOI rely on coded conditions to reflect how sick a patient is and how likely they are to have adverse outcomes. When documentation is incomplete, important comorbidities or acute issues may not be coded, leading to lower severity and mortality scores. This undercoding translates into an underestimation of overall risk and produces biased population health metrics that don’t accurately reflect the true mix of illness in the SAMPLEpopulation. While it’s possible to imagine scenarios where documentation would inflate risk, gaps more often depress risk scores rather than raise them. And these gaps affect risk adjustment, not just length of stay, since LOS is influenced by many factors beyond the coded risk.
