Overview of Chronic Condition Indicator Refined (CCIR) for ICD-10-CM

The Chronic Condition Indicator Refined (CCIR) for ICD-10-CM facilitates health services research by allowing the researcher to readily identify a diagnosis as indicating a chronic condition. Beginning v2023.1, the CCIR for ICD-10-CM returns to a concept consistent with the ICD-9-CM version of the tool, which distinguishes chronic from non-chronic conditions. All ICD-10-CM diagnosis codes are identified as one of the following three categories:

  • Chronic (value 1)
    • Examples include malignant cancer, diabetes, obesity, hypertension, and most mental health conditions

  • Not chronic (value 0)
    • Examples include influenza, bacterial infection, pregnancy, and most initial encounters for an injury

  • No determination is made on the identification of a chronic condition (value 9)
    • Examples include external cause of morbidity codes, and codes indicating a fracture or complication of a prosthetic, prosthetic device, or other device, implant, or graft.

The Chronic Condition Indicator Refined (CCIR) for ICD-10-CM is updated annually to coincide with fiscal year updates to the ICD-10-CM coding system and retains diagnosis codes valid from the start of ICD-10-CM in October 2015. For this reason, it is advisable to always use the most recent version of the tool.
