Outcome Evidence

• In 2015, the ICD-9 codes were updated to ICD-10 after 30 years. There was concern among providers over the disruption the transition would cause. A study conducted 6 months post transition found that most claims were submitted and processed successfully. There were no reports of a high rate of claims denials or rejections, or  notable decreases in the volume of claims submitted. source
