ICD-10-PCS stands for International Classification of Diseases 10th Revision Procedure Coding System.
These revised codes have replaced ICD-9-CM Volume 3. In addition to ICD-10-CM diagnosis codes, ICD-10-PCS contains additional inpatient procedure codes that hospitals must use for reimbursement.
CMS Deadlines: CMS no longer allows a 90-day grace period for using discontinued codes, so get your books early and stay up-to-date! You must use valid ICD-10-PCS codes for services performed on or after October 1, 2019.
