Charlson Comorbidity scoring in pre-ICD10 codes

This page explains how the actual Charlson Comorbidity Index is derived from the pre-IDC10 dx codes need to link.

Short version

To get the Charlson comorbid points for a patient, use query pre_ICD10_Charlson_Score

Long version

Points are not included in the listings because the score depends on the combination of diagnoses. For example, if a patient has two diagnoses from the same Charlson component, they are only counted once. Also, if a patient has diagnoses from a lesser and more severe component of the same type (e.g. Diabetes without and with complications), only the higher one counts.
