When and when not to use new subsequent observation codes

Article Overview

This article explains how different payer and code-authority guidance can affect billing for observation care when a patient is seen by more than one physician or seen again after an initial observation encounter. It is aimed at coders, billing staff, and clinicians who need to understand how CMS, CPT, and a private payer may approach the same observation-care situations differently. The discussion focuses on the general categories of observation and E/M guidance involved, without replacing the premium article’s detailed comparison.
