Clinical Context
A typical patient is a 58-year-old male who presents with progressive dyspnea, chest pain, and echocardiographic evidence of a moderate to large pericardial effusion with signs of early tamponade. After clinical evaluation in the emergency department and confirmation by transthoracic echocardiography, the cardiothoracic surgery or interventional pulmonology team performs a thoracoscopic pericardial biopsy and fluid sampling using an endoscope to visualize the thoracic cavity and pericardial sac. The procedure is typically performed in an operating room or procedure suite under general anesthesia with endotracheal intubation. Intraoperative steps include thoracoscopic visualization of the pleural and pericardial spaces, targeted biopsy of abnormal pericardium, aspiration of pericardial fluid for microbiology and cytology, placement of a pericardial drain if indicated, and sending tissue/fluid specimens to pathology for histologic and microbiologic evaluation. Post-procedure monitoring occurs in a post-anesthesia care unit with telemetry; discharge planning depends on clinical stability, hemodynamics, and pathology results.
Coding Specifications
| Modifier | Description | When to Use |
|---|
22 | Increased procedural services | Use when work or time substantially exceeds typical for the procedure due to complexity, extensive adhesiolysis, or other factors increasing effort |
| 23 | Unusual anesthesia | Use when the procedure is performed under general anesthesia for an otherwise normally local-procedure-level service because of patient condition
| 26 | Professional component | Use when reporting only the physician interpretation component if the facility bills the technical component separately
| 50 | Bilateral procedure | Use if bilateral thoracoscopic access and sampling of both pericardial surfaces are performed and payer rules permit
| 51 | Multiple procedures | Use when additional unrelated procedures are performed at the same session and bundling rules require reporting multiple-procedure modifier
| 52 | Reduced services | Use when the procedure is attempted but substantially reduced, incomplete, or aborted for reasons not meeting a separate abortive-procedure code
| 53 | Discontinued procedure | Use when the procedure is terminated due to extenuating circumstances or patient safety prior to completion
| 62 | Two surgeons | Use when two surgeons with distinct specialties operate together and both contribute to a portion of the procedure
| 78 | Return to OR for related procedure during global period | Use when patient returns to the operating room for a related procedure during the global postoperative period
| 80 | Assistant surgeon | Use when an assistant surgeon (other than co-surgeon) contributes intraoperative assistance
| 81 | Minimum assistant surgeon | Use when a minimal assistant contribution is reported per payer rules
| 82 | Assistant (when qualified resident not available) | Use when an assistant is required and no qualified resident is available
| TC | Technical component | Use when reporting only the technical component (facility) of a service when the physician only provides technical resources
| QK | Medical direction of two, three, or four concurrent anesthesia procedures | Use in anesthesia-related reporting when directing multiple concurrent cases that include this procedure
| U1 | March 2021 MIPS-related modifier (example) | Use per payer-specific reporting requirements when applicable to quality reporting
