CRNA (Nurse Anesthetist) Anesthesia Coding in the ASC
Certified Registered Nurse Anesthetists (CRNAs) deliver anesthesia and peri-operative care across ambulatory surgery centers (ASCs). That work maps almost entirely to the anesthesia CPT family, 00100 through 01999. These codes are organized by the body region or procedure being anesthetized rather than the technique, so a knee replacement maps to 01402 (Anesth knee arthroplasty) and pharyngeal surgery to 00176 (Anesth pharyngeal surgery).
Coverage and payment in an ASC follow the underlying surgical procedure and payer rules rather than a single anesthesia line item, so it helps to read each code next to the surgical CPT it supports. DataLily's procedure library tracks CPT-specific prior-authorization and documentation requirements so peri-operative teams can confirm what each case needs before the day of surgery.

Do CRNAs provide anesthesia in ambulatory surgery centers?
Yes. CRNAs are a common part of the anesthesia and peri-operative team in ASCs, handling pre-operative assessment, intra-operative anesthesia, and recovery support across most surgical specialties an ASC schedules. Anesthesia delivered in an ASC is billed with place of service 24.
What CPT codes does a CRNA use?
CRNA anesthesia services fall in the anesthesia CPT family, 00100 through 01999. Each code corresponds to the procedure or body region being anesthetized rather than the anesthetic method. Examples include 01402 for knee arthroplasty anesthesia, 00211 for anesthesia during cranial surgery for hematoma, and 00192 for facial bone surgery anesthesia.
How are anesthesia codes chosen for a surgical case?
The anesthesia code is selected to match the surgical procedure being performed, so anesthesia coding tracks the underlying surgery. For example, pharyngeal surgery maps to 00176. Because coverage and payment in an ASC follow the underlying procedure and payer rules, it is best to confirm the surgical CPT, place of service, and any prior-authorization or documentation requirements before the date of service.
