Article Overview
This article explains common office-based anticoagulation clinic workflows for patients receiving warfarin therapy and discusses the documentation and medical-necessity considerations surrounding a nurse face-to-face evaluation in that setting. It is aimed at coders, billers, and physician office staff who need to understand when an evaluation and management service may be associated with routine Coumadin testing and when a simple test visit is not enough. The article focuses on general coding and compliance considerations related to office encounters, nursing interaction, and follow-up activities.
