A successful transition from ICD-9-CM, Volume 3, to the ICD-10-PCS coding system will require focused training for individuals and organizations. The first step is to understand that procedure codes are built from a range of variables including root operation, body system, body part, approach and more—not selected from a list. Multiple codes may even be needed in some instances. Beginning and advanced coders will benefit from Detailed Instruction for Appropriate ICD-10-PCS Coding, which goes beyond the official guidelines by anticipating questions and points of confusion. This resource will help with mastery of ICD-10-PCS coding, an essential skill since reimbursements for Medicare inpatient services make up a significant portion of hospital revenues.
