Reserved for patients with life-threatening illness or injury where a physician provides direct, continuous care for at least 30 minutes.
Based on typical US negotiated and cash-pay rates. Hospital charges can run significantly higher — often 2–10x these numbers. If your bill is well above this range, it's worth questioning.
- Billed for a patient who was stable and discharged home.
- Billed alongside a standard ER E&M code (99281–99285) for the same time.
- No documented 30+ minute continuous physician attendance.
Request the physician's time-based documentation. Without it, this code cannot be supported — appeal.

Can I dispute a charge for CPT 99291?
Yes. You have the right to request an itemized bill, dispute the coding with the provider's billing office, and appeal the insurer's decision. Federal rules (including the No Surprises Act for emergency and out-of-network ancillary services) protect you from many surprise charges. BillCheck can generate the appeal or negotiation letter for you.
