E/M Coding

Level selection by MDM or time, split/shared visits, and prolonged services.

E/M is the highest-volume code family in most practices and the one auditors sample first. Since the 2021 and 2023 revisions, level selection runs on medical decision making or total time, which changed what the note must show.

These articles work through MDM elements with examples, time-based selection and what counts toward it, split and shared visits, prolonged service codes, and the level distributions that draw payer attention.
