ICD-9/ICD-10 Tools
ICD codes are standardized alphanumeric codes used to classify diseases and health conditions. They facilitate the collection, analysis, and comparison of health information globally, aiding in health management and research. While several versions have been used previously, ICD-10 is the most recent and currently used. These code sets include:
- ICD-10-CM codes are used for classifying diagnoses in both inpatient and outpatient settings.
- ICD-10-PCS codes are designed for coding medical procedures in an inpatient setting
The primary analytic tool for ICD codes is the Clinical Classification Software Refined (CCSR) developed by the Agency for Healthcare Research and Quality (AHRQ).
- Clinical Classifications Software Refined (CCSR)
- CDC Classification of Diseases, Functioning and Disability, 10th Revision
Conversion Tool for the ICD-9 CM to ICD-10 CM Transition
Some systems have not completed their transition from ICD-9 to ICD-10. NAHDO offers a transition tool that:
- Easily flags invalid codes and incorrect records
- Runs quickly on very large data sets with multiple dx per record
- Shared codes between ICD-9 and ICD-10 are allocated according to other codes on the same record and E coding rules

The Future: ICD-11
ICD-11 is the latest revision of the World Health Organization’s (WHO) International Classification of Diseases (ICD). It incorporates current medical knowledge and clinically intuitive coding structures for healthcare providers, researchers, and decision-makers.
WHO stopped maintaining ICD-10 in 2018, and future enhancements will be introduced only in ICD-11. Countries can continue to use ICD-10 for as long as necessary, but prompt adoption of ICD-11 is encouraged to ensure interoperability, consistency with global standards, benefit from ongoing enhancements, and compliance with international commitments.
