A new toolkit developed by Dr. Elizabeth Magnan is available on HIPxChange. The Algorithm for Identifying Patients with Multiple Chronic Conditions (Multimorbidity) contains over 4,000 ICD-9 codes that are mapped to AHRQ Clinical Classification Software (CCS) codes, which are then bundled into 69 clinically relevant chronic condition categories. Researchers can use these categories to examine the effect of multiple chronic conditions or specific comorbidities on health and outcomes, or in quality improvement or public reporting work.
