Endotracheal Intubation FAQs

What is endotracheal intubation?

A procedure whereby a plastic tube is placed through the nose or mouth and into the trachea. In the emergency department, this procedure is most often performed by a stepwise process called rapid sequence intubation (RSI). First, medications are administered to sedate and paralyze the patient. Second, a view of the airway is obtained using a rigid laryngoscope or flexible bronchoscope. Third, the endotracheal tube is guided into the trachea and secured. Placement is typically verified by direct visualization, lung auscultation, and/or capnography. Position is typically confirmed by chest x-ray.

What CPT code is used to document intubation in the emergency department?

31500

Is the same code applied if a video laryngoscope is used? What about an intubation performed using a flexible fiberoptic bronchoscope?

Yes, code 31500 applies to intubations performed with rigid laryngoscopes (standard geometry, hyper-angulated geometry, with or without video).

CPT code 31500 also applies to intubations performed using a flexible fiberoptic bronchoscope.

What documentation is required for the intubation procedure note?

While it is generally best practice to include details of the procedure, the only required documentation is a statement indicating that intubation was performed.

Can you bill separately for the administration of medications (induction/paralytic agents) used to complete the intubation?

No, medication administration to complete an endotracheal intubation is included in CPT code 31500.

Can an intubation be billed in addition to critical care time?

Yes, as a separately reportable service with Critical Care, the time spent performing the intubation cannot be counted in calculating total Critical Care time.
