Evaluation and Management (E/M) coding is how office visits, consultations, and similar encounters are reported by level of complexity. For office and outpatient visits, the level is chosen based on the complexity of medical decision-making or on the total time spent on the day of the encounter.
Choosing the level is a documentation exercise: the note has to support the decision-making or the time claimed. E/M codes are among the most frequently billed, so small errors add up quickly.
Why it matters for billing
Because E/M services are billed constantly, consistent leveling has an outsized effect on both revenue and audit risk. Coding too high invites recoupment; coding too low gives away earned income. Documentation aligned to current E/M guidelines is what keeps leveling defensible.

Because these codes are billed in high volume, payers watch leveling patterns closely; documentation must support whichever level is reported.
