Charlson Comorbidity scoring in pre-ICD10 codes
This page explains how the Charlson Comorbidity Index score is derived for data prior to Conversion from our old diagnosis schema to ICD10/CCI.
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.
