ICD-10-CM primer.

The system consists of more than 68,000 codes, compared to approximately 13,000 ICD-9-CM codes. ICD-10-CM codes have the potential to reveal more about quality of care, so that data can be used in a more meaningful way to better understand complications, better design clinically robust algorithms, and better track the outcomes of care. ICD-10-CM incorporates greater specificity and clinical detail to provide information for clinical decision making and outcomes research.
