Time-Based Coding

Selecting an E/M code based on total time on the date of encounter rather than MDM. Per 2021 CPT revision: 99202 (15-29 min new), 99203 (30-44), 99204 (45-59), 99205 (60-74); 99212 (10-19 established), 99213 (20-29), 99214 (30-39), 99215 (40-54). Time includes face-to-face plus non-face-to-face on the same date: chart review, ordering tests, documentation, care coordination, communication with the patient or family. Time must be documented explicitly (e.g., "Total time spent on date of encounter: 32 minutes").
