Clinical Classifications Software Refined (CCSR) for ICD-10-CM Diagnoses





Updated: Clinical Classifications Software Refined (CCSR) for ICD-10-CM Diagnoses

AHRQ has released the Clinical Classifications Software Refined (CCSR) for ICD-10-CM diagnoses, v2020.2. This update includes the ability to assign a single CCSR category for the principal diagnosis. Since individual diagnoses can be assigned to more than one CCSR category, some analyses such as ranking hospitalizations need to prioritize the CCSR selection for the principal diagnosis. This version also adds a new CCSR category for low back pain, and aligns the CCSR categories for external cause of morbidity codes to the finalized Centers for Disease Control (CDC) External Cause of Morbidity matrix.

The HCUP family of healthcare databases and related software tools and products is made possible by a Federal-State-Industry partnership sponsored by the Agency for Healthcare Research and Quality (AHRQ).
