How can a documented and correctly coded MCC on the secondary diagnosis list affect inpatient payment?
Select an answer to reveal the explanation.
Short Explanation
An MCC is like upgrading from economy to a higher fare class when the clinical story supports it. If it’s in the chart and coded right, the Grouper may move the case to a richer severity tier. No documentation, no upgrade—and it never swaps inpatient for outpatient.
Full Explanation
Major complication or comorbidity (MCC) codes, when clinically documented and correctly reported as secondary diagnoses, can move a base MS-DRG into a higher-paying MCC severity tier. MCCs do not replace principal diagnosis, convert IPPS to OPPS, or by themselves trigger outlier payments. Ethical coding requires clinical support for every MCC reported.
