CPT Code Overview
CPT 01173 is designated for anesthesia services provided during procedures on the pelvis (except hip). This code is used to report the professional work of anesthesia care for pelvic surgeries, excluding those involving the hip. The service type is anesthesia, and the typical site of service is an inpatient hospital setting (POS 21). This code is essential for accurately documenting and billing anesthesia care in complex pelvic procedures, ensuring proper reimbursement and compliance with national standards.
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult admitted to an inpatient hospital for a surgical procedure on the pelvis (excluding the hip), such as pelvic fracture repair or gynecologic surgery. The patient may have underlying conditions like osteoarthritis or a history of joint replacement, as indicated by the associated ICD-10 codes. An anesthesiologist or certified registered nurse anesthetist (CRNA) provides anesthesia services to ensure the patient is safely sedated and pain-free during the procedure. The clinical workflow includes preoperative assessment, administration of anesthesia, intraoperative monitoring, and postoperative care in the hospital setting.
Coding Specifications
| Modifier Code | Description | When Used |
|---|---|---|
AA | Anesthesia services performed personally by anesthesiologist | When the anesthesiologist provides the service directly |
QK | Medical direction of two, three, or four concurrent anesthesia procedures | When an anesthesiologist supervises multiple procedures |
QX | CRNA service with medical direction by a physician | When a CRNA provides anesthesia under physician direction |
QZ | CRNA service without medical direction by a physician | When a CRNA provides anesthesia independently |
