DHCS will begin accepting ICD-10 codes for claims with dates of service on and after October 1, 2015. DHCS will be monitoring claims processing closely and will be able to respond to questions quickly. We look forward to October 1, 2015 when we will be in full compliance with the CMS final rule.

The International Classification of Diseases, 10th Revision (ICD-10) is a diagnosis and procedure coding system replacing the ICD-9 coding system. Due to the enhanced specificity and level of detail of the ICD-10 code set, the transition is anticipated to have a significant impact on Medi-Cal, health plans, health care providers and trading partners. The ICD-10 Clinical Modification (CM) and Procedure Coding System (PCS) codes will improve the ability to govern reimbursement, monitor a population’s health, track trends in disease and treatment, and optimize health care delivery.

This change will impact reimbursements, so it is important to prepare for the upcoming changes. The Latest News for ICD-10 is available on the Centers for Medicare & Medicaid Services website. The links below provide additional information about ICD-10. Providers and submitters are encouraged to check this page periodically for new information.
