Chronic Conditions
The Chronic Conditions data mart implements two versions for classifying chronic condition categories.
CMS: This version uses the logic created by CMS. There are 30 CCW Chronic Condition categories, available for file years 2017 forward, and 40 other chronic health, mental health, substance abuse, and potentially disabling condition categories available for file years 2000 forward. These reference only ICD-10 diagnosis codes and have modified look-back periods, qualifying claims, and codes. You can read more about CMS's logic here.
Tuva: A less strict interpretation of chronic conditions relying on Core Patient and Condition only.
cms_chronic_conditions_long
This table contains one record per patient per chronic condition. For example, if a patient has 3 chronic conditions they will have 3 records in this table. Each record includes the condition category, condition, date of onset, most recent diagnosis, and the total count of diagnosis codes that were recorded that are relevant for the condition.
This table is created by running the CMS chronic conditions data mart on data that's been mapped to the core data model.
Primary Keys:
- patient_id
- condition
