It includes some commonly found ICD-10 codes. This list was compiled from the ICD-10-CM 2015 AMA manual. A current ICD-10-CM book should be used as a complete reference. The ultimate responsibility for correct coding belongs to the ordering physician. Sonora Quest Laboratories, the associated logo and marks are the registered trademarks of Sonora Quest Laboratories.
