This is metric is sometimes used, with well known limitations (e.g. very sick people don't get minor diseases coded).

Will be very easy to count across the co-morbidity matrix to return these values.

This relies on correctly avoiding double-counting , e.g. if you have metastasis, you already have cancer, and some co-morbidity mappings account for this. Deyo/Charlson 1992 does.
