Overview of Chronic Condition Indicator for ICD-10-CM (beta version)

The Chronic Condition Indicator for ICD-10-CM (beta version) facilitates health services research by allowing the researcher to readily identify a diagnosis as indicating a chronic condition. Prior to v2021.1 (beta version), the CCI distinguished chronic from non-chronic conditions. Starting in v2021.1 (beta version), the CCI tool was expanded to identify four types of conditions:
  • Chronic
    • Examples include malignant cancer, diabetes, obesity, hypertension, and many mental health conditions

  • Acute
    • Examples include aortic embolism, bacterial infection, pregnancy, and an initial encounter for an injury

  • Both
    • Examples include persistent asthma with (acute) exacerbation, acute on chronic heart failure, and kidney transplant rejection

  • Not applicable (code cannot be used to identify a chronic or acute condition)
    • Examples include external cause of morbidity codes, injury sequela codes, and codes starting with the letter Z for screening or observation.

The Chronic Condition Indicator for ICD-10-CM (beta version) 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.

In 2021, AHRQ expects to conduct additional empirical analyses of the beta version of the tool and transition it out of beta status. User feedback on v2021.1 is appreciated and will be taken into consideration. Comments can be sent to hcup@ahrq.gov.
