Article Overview
This premium article examines a Medicare Part B coding myth about using claimed visit time to support higher-level office and outpatient evaluation and management coding. It walks through documentation requirements, compares time-based selection with history/exam/medical decision-making-based selection, and highlights why auditors focus on what is actually recorded. The article is relevant to coders, auditors, compliance staff, and clinicians who document E/M services.
