The Centers for Medicare and Medicaid Services (CMS) and the National Center for Health Statistics (NCHS) continue to update the official guidelines related to ICD-10-CM/PCS coding. This article summarizes the ICD-10-PCS guidelines only, including one significant change from the FY 2013 guidelines.
A quick review of the introductory section emphasizes that the 2014 guidelines are a set of rules developed to accompany and complement the official conventions and instructions provided within the ICD-10-PCS itself. As a reminder, the instructions and conventions within ICD-10 take precedence over these guidelines. Although based on the coding and sequencing instructions in the Tables, Index and Definitions of ICD-10-PCS, the guidelines provide additional instruction. Also important to remember is that the Healthcare Insurance Portability and Accountability Act (HIPAA) requires that providers adhere to these guidelines when assigning ICD-10-PCS procedure codes, which HIPAA mandated for use in the hospital inpatient setting.
