CPT Code Overview

CPT code 00532 is designated for anesthesia services related to access of central venous circulation. This procedure is typically performed as part of intrathoracic procedures requiring specialized anesthesia care. The most common site of service for this code is the inpatient hospital setting (Place of Service 21). These services are essential for patients undergoing complex surgical interventions where central venous access is necessary for medication administration, monitoring, or other clinical needs.

Clinical & Coding Specifications

Clinical Context

A patient is admitted to an inpatient hospital for a procedure requiring access to central venous circulation. This typically involves the placement of a central venous catheter for purposes such as medication administration, hemodynamic monitoring, or other intrathoracic interventions. An anesthesiologist provides anesthesia services to ensure patient comfort and safety during the access procedure. The clinical workflow includes pre-anesthesia assessment, administration of anesthesia, monitoring throughout the procedure, and post-procedure care.

Coding Specifications

Modifiers:
- Modifier G8: Used to indicate that the anesthesia service is for a deep, complex, complicated, or markedly invasive surgical procedure.
- Modifier G9: Applied when the patient has a history of severe cardiopulmonary disease, necessitating monitored anesthesia care.
