Coronary artery bypass graft (CABG) procedures are not the only ones coders will report using the root operation Bypass in ICD-10-PCS. Surgeons can create bypasses in other vessels of the body.
Despite all the uncertainty surrounding the implementation of ICD-10-CM/PCS, the Cooperating Parties (i.e., the American Hospital Association, AHIMA, CMS, and the National Center for Healthcare Statistics) nevertheless decided that the farewell issue of Coding Clinic for ICD-9-CM (which was published in the first quarter of 2014) will remain the farewell issue.
Inpatient coding professionals are used to DRG systems where all of the diagnoses and procedures map to a single DRG. So they may not look for additional procedures and services to report outside of that DRG.
