The 2021 ICD-10-CM Expert for Physicians with Guidelines, with our hallmark features and format, makes facing the challenge of accurate diagnosis coding easier. Developed specifically to meet the needs of physicians, the Optum360 codebook contains the complete ICD-10-CM code set, which is the cornerstone for establishing medical necessity, determining coverage, and ensuring appropriate reimbursement. Symbols in the tabular section identify codes associated with CMS quality payment program (QPP) measures and CMS hierarchical condition categories (HCC) used in risk adjustment (RA) coding. Supplementary appendixes available only in the expert edition include: pharmacology listings, Z codes for long-term use of drugs and associated drug names, and Z codes used only as primary diagnosis.
Delivery might be delayed beyond the October 1, 2020, effective date. Delivery is dependent on when the updated Official Guidelines for Coding and Reporting for 2021 are released from CMS.
