CPT 00522: Anesthesia for Closed Chest Needle Pleural Biopsy
CPT code 00522 represents anesthesia services for a closed chest needle biopsy of the pleura, a procedure used to sample pleural tissue or fluid adjacent to the lungs. This code is relevant nationally because it defines anesthesia billing for a focused intrathoracic diagnostic procedure that often accompanies acute respiratory or thoracic disease management. Accurate use of CPT code 00522 affects hospital and anesthesia group reimbursement, resource allocation, and coding compliance for intrathoracic diagnostic procedures.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise overview of the clinical context for the code, typical sites of service, and common payer considerations. The content highlights related service codes and the typical scenarios in which CPT code 00522 is reported, offering clarity on documentation and billing context.
The publication summarizes benchmarks and policy-relevant guidance for national audiences, providing practical reference on code definition, common clinical indications, and service setting. It also outlines associated coding relationships and contrasts CPT code 00522 with closely related intrathoracic anesthesia codes to aid coding accuracy and administrative clarity.

Billing Code Overview
CPT code 00522 describes anesthesia services provided for a closed chest procedure involving a needle biopsy of the pleura. The service reflects administration and management of anesthesia during a needle pleural biopsy performed through the chest wall without open thoracotomy.
Service Type: Anesthesia for closed chest pleural needle biopsy
Typical Site of Service: Hospital operating room or procedure suite, inpatient or outpatient surgical setting
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with a history of ischemic heart disease (I25.10), prior myocardial infarction (I21.9), and chronic heart failure (I50.9) presents with progressive dyspnea and a persistent pleural effusion. Chest imaging localizes a unilateral pleural-based opacity suspicious for malignancy or complicated parapneumonic effusion. After multidisciplinary discussion, the patient is scheduled for a closed-needle pleural biopsy under monitored anesthesia care using CPT 00522 for anesthesia services.
Pre-procedure workflow includes focused cardiac and pulmonary assessment, review of recent anticoagulation, informed consent, IV access placement, and peri-procedural monitoring (ECG, pulse oximetry, blood pressure). The anesthesia team evaluates cardiac risk given comorbid valvular disease (I34.0, I35.0) and optimizes sedation plan—typically moderate sedation or monitored anesthesia care with readiness to convert to general anesthesia if complications occur. The procedure is performed in an interventional radiology suite or thoracic procedure room with post-anesthesia recovery monitoring. Post-procedure care includes observation for pneumothorax, hemodynamic stability, pain control, and pathology specimen handling for histology and culture.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when anesthesia or procedural complexity substantially exceeds usual requirements due to patient comorbidities or technical difficulty. |
23 | Unusual anesthesia | Use when general anesthesia is medically necessary but the procedure is normally done with local/regional or no anesthesia. |
50 | Bilateral procedure | Use if identical pleural biopsies are performed on both hemithoraces during the same anesthetic. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as planned but not terminated. |
53 | Discontinued procedure | Use when the procedure is terminated due to extenuating circumstances or safety concerns after anesthesia initiation. |
54 | Surgical care only | Use when the anesthesia provider bills only for intraoperative anesthesia time and other professionals bill separately for pre/post care (rare for anesthesia billing). |
55 | Postoperative management only | Use when the anesthesia professional provides only postoperative pain management or follow-up, separate from intraoperative care. |
62 | Two surgeons/physicians | Use when two qualified physicians work together as primary surgeons; applicable if anesthetic billing needs to reflect shared operative responsibility influencing anesthesia plan. |
78 | Return to OR for related procedure | Use when patient returns to the operating room for a related procedure following initial anesthesia within the global period. |
AA | Anesthesia by anesthesiologist | Use when an MD/DO anesthesiologist personally performs the anesthesia. |
AD | Medical supervision by anesthesiologist | Use when the anesthesiologist supervises a Certified Registered Nurse Anesthetist (CRNA) and performs key portions personally. |
AS | Physician assistant/assistant at surgery | Use when a physician assistant provides intraoperative assistance relevant to billing relationships. |
QK | Medical direction of two to four CRNAs/AAIs | Use when the anesthesiologist medically directs multiple CRNAs/Anesthesiologist Assistants during the case. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Board-certified anesthesiologists provide MAC or general anesthesia and complex perioperative management. |
367500000X | Certified Registered Nurse Anesthetist | CRNAs frequently deliver monitored anesthesia care or sedation for pleural procedures under supervision or medical direction. |
367H00000X | Anesthesiologist Assistant | Anesthesiologist assistants support delivery of anesthesia under physician supervision in applicable states/institutions. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
I21.9 | Acute myocardial infarction, unspecified | Important comorbidity increasing peri-procedural cardiac risk and informing anesthesia planning and monitoring. |
I25.10 | Atherosclerotic heart disease of native coronary artery without angina pectoris | Chronic coronary disease affects risk stratification and perioperative hemodynamic management during sedation or anesthesia. |
I50.9 | Heart failure, unspecified | Heart failure influences fluid management, sedation choice, and post-procedure monitoring for respiratory or hemodynamic compromise. |
I34.0 | Nonrheumatic mitral (valve) insufficiency | Valvular regurgitation alters hemodynamic tolerance to sedation and may necessitate invasive monitoring or anesthetic adjustments. |
I35.0 | Nonrheumatic aortic (valve) stenosis | Aortic stenosis is a high-risk cardiac condition requiring careful anesthesia planning; may change sedation depth and hemodynamic targets. |
