CPT 01920: Anesthesia for Coronary Angiography and Ventriculography
CPT code 01920 represents anesthesia services for patients undergoing coronary angiography and ventriculography when Swan–Ganz catheterization is not performed. This code captures the anesthesiologist’s role in providing peri-procedural sedation, airway and hemodynamic management, and anesthetic care specifically tied to invasive diagnostic cardiac imaging. Nationally, accurate use of this code affects clinical documentation, hospital billing, and payment for cardiac catheterization cases where anesthesia is required.
Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines payer coverage considerations and coding contexts relevant to these payers without presenting state-level variation.
Readers will find a concise clinical context for when 01920 is appropriate, comparisons to related anesthesia services, typical site-of-service considerations (hospital cath lab or cardiac interventional suite), common associated diagnoses encountered with these procedures, and related procedural codes to distinguish scope of service. The report also summarizes common modifiers and coding scenarios used with procedural anesthesia codes and highlights areas where documentation should align with the billed code. This information is intended to support accurate claim submission and coding consistency for anesthesia services tied to diagnostic coronary angiography and ventriculography.

Billing Code Overview
CPT code 01920 describes anesthesia services provided for coronary angiography and ventriculography procedures that do not include Swan–Ganz catheterization. The service involves administration and management of anesthesia during invasive cardiac imaging to assess coronary arteries and ventricular function.
-
Service type: Procedural anesthesia for diagnostic coronary angiography and ventriculography
-
Typical site of service: Hospital catheterization laboratory or specialized cardiac interventional suite
Clinical & Coding Specifications
Clinical Context
A 67-year-old male with hypertension and known coronary artery disease is admitted for evaluation of progressive exertional chest pressure. Noninvasive testing is inconclusive and the cardiology team schedules invasive coronary angiography with left ventriculography to assess coronary anatomy and left ventricular function. The patient arrives to a cardiac catheterization suite in an outpatient hospital setting. Preoperative evaluation by the anesthesia team documents American Society of Anesthesiologists (ASA) physical status P3 due to prior myocardial infarction and controlled heart failure. Monitors are applied, intravenous access is confirmed, and sedation with monitored anesthesia care (MAC) is planned to maintain patient comfort and hemodynamic stability during femoral arterial access, coronary contrast injections, and ventriculography. Anesthesia services include airway assessment, sedation titration, hemodynamic monitoring, vasoactive medication availability, and readiness for conversion to general anesthesia if needed. The procedure does not include Swan–Ganz (pulmonary artery) catheter placement. Postprocedure recovery occurs in a monitored PACU or cardiac observation area with anesthesia handoff and documentation of airway status, medications administered, hemodynamics, and any complications.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
23 | Unusual anesthesia | Use when general anesthesia is medically required but not anticipated for a usually non‑operative diagnostic procedure. |
52 | Reduced services | Use when anesthesia time or services are partially reduced or procedure aborted. |
53 | Discontinued procedure | Use when the procedure is terminated for patient safety before completion. |
62 | Two surgeons | Use when two qualified anesthesiologists are required for simultaneous critical tasks (rare for this code; more commonly a surgical modifier but included per list relevance). |
76 | Repeat procedure by same provider | Use when anesthesia is repeated later the same day by the same clinician. |
78 | Return to OR/Procedure for related procedure | Use if the patient returns to the catheterization lab for a related procedure requiring additional anesthesia. |
AA | Anesthesia by anesthesiologist | Use when the service is personally performed by a physician anesthesiologist. |
AD | Medical direction by physician | Use when the physician medically directs qualified personnel in providing anesthesia services. |
AS | Physician Assistant (Anesthesia) | Use when an anesthesia assistant performs the service under appropriate supervision where allowed. |
QX | CRNA service: medically directed by physician | Use when a CRNA performs the service under medical direction by a physician. |
QK | Medical direction of two, three, or four CRNAs | Use when an anesthesiologist directs multiple CRNAs during the anesthetic. |
QS | Monitored Anesthesia Care (MAC) | Use to indicate monitored anesthesia care was provided. |
59 | Distinct procedural service | Use to indicate a distinct service when multiple procedures or anesthesia codes are reported on the same day. |
22 | Increased procedural services | Use when the anesthesia service requires substantially greater resources or time than typical, documented and justified. |
52 | Reduced services | Use when parts of the usual anesthesia service were omitted or reduced (included for emphasis when appropriate). |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Primary providers for administration of anesthesia services in the catheterization lab. |
207RA0000X | Cardiac Anesthesiologist | Subspecialist who manages complex cardiac patients and perioperative cardiac hemodynamics. |
207RC0000X | Cardiovascular Disease Physician | Proceduralists performing coronary angiography; coordinates with anesthesia for patient stability. |
