Description
The current implementation of the CCI in the FeatureExtraction package does not account for mutually exclusive comorbid condition categories; e.g.:
• When both mild vs. moderate to severe liver disease are observed, only the weights for moderate to severe liver disease should be counted
• When both diabetes with vs. without complications are observed, only the weights for diabetes with complications should be counted
• When both ‘any malignancy’ and metastatic tumor are observed, only the weights for metastatic tumor should be counted

Research direction
Start by locating the CCI implementation in the FeatureExtraction package and any existing CCI-related tests. Review how comorbid condition categories are selected and weighted. Done means mutually exclusive pairs keep only the more severe category in each of the three examples described in the issue, with tests covering those cases.
