What CPT 99213 covers
99213 reports a low-complexity established visit. Typical support is one stable chronic illness, or an acute uncomplicated problem with limited data — or 20–29 minutes of total time. It is the workhorse of primary care.
Because 99213 is so common, small documentation habits add up across a whole panel. We help practices bill it consistently and correctly — and, just as important, recognize when a visit actually earned 99214 so moderate work is not routinely left on the table as a 99213.
It fits an established patient with a stable chronic condition, or two minor problems — the everyday follow-up that makes up much of a primary-care schedule.

Common 99213 denials — and how we prevent them
| Why it is flagged | How we avoid it |
|---|---|
| Chronic under-coding | We flag visits that met moderate complexity so genuine 99214 work is not defaulted to 99213. |
| Level not documented | When neither time nor low MDM is clear, we query before billing. |
| Time without a total | If time is the basis, a documented total in minutes is required. |
