99232 FAQ
Plain-English answers.
If I had a 5-day hospital stay, should every day be 99232?
Almost certainly not. A typical 5-day medical admission has one initial visit (99221–99223), zero to two days of moderate-complexity follow-up (99232) when treatment is actively being adjusted, and the rest as low-complexity (99231) once the patient stabilizes. Five straight 99232 charges should be questioned.
