Summary & Overview
CPT 32035: Thoracostomy and Rib Excision for Empyema
CPT code 32035 designates a surgical thoracostomy with excision of a rib to remove empyema from the pleural cavity. This is an important code for thoracic surgery and inpatient procedural billing because it captures a definitive surgical approach to complicated pleural infections that are not amenable to less invasive drainage. Nationally, accurate use of this code affects inpatient surgical case mix, resource allocation, and payment for complex thoracic care.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical framing of the procedure, typical sites of service, and the service type. The publication also summarizes payer coverage patterns and common modifiers where available, highlights coding and billing considerations relevant to hospital and surgical providers, and situates the code within clinical care pathways for empyema.
The report is intended to inform revenue cycle professionals, coding auditors, and clinical leaders about the clinical intent of CPT code 32035, common billing practices, and areas where policy updates or documentation clarity can affect payment and reporting. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 32035 describes a surgical procedure in which the provider performs a thoracostomy (creating an artificial opening in the chest wall) followed by excision of a rib to remove empyema, an accumulation of pus in the pleural cavity. This procedure is categorized as a thoracic surgical service addressing complicated pleural space infections that require direct access and debridement.
-
Service type: Surgical — thoracic/rib excision for empyema
-
Typical site of service: Operating room or procedural suite in an inpatient or specialized ambulatory surgical setting, depending on patient stability and clinical needs.

Clinical & Coding Specifications
Clinical Context
A 58-year-old male with a history of chronic obstructive pulmonary disease and recent community-acquired pneumonia presents with persistent fever, pleuritic chest pain, and dyspnea. Chest imaging (CT and chest x-ray) demonstrates a loculated pleural effusion with air-fluid levels and pleural thickening consistent with empyema. The patient undergoes operative management in the operating room by a thoracic surgeon. Under general anesthesia, a thoracostomy is created and an infected pleural space is drained. A segmental rib excision (rib resection) is performed to gain access, facilitate debridement, and allow placement of wide drainage and irrigation for removal of purulent material. Intraoperative cultures are obtained; chest tubes are placed for postoperative drainage. Postoperative care includes ICU or step-down monitoring with targeted antibiotics based on culture results and planned chest tube management and possible wound care.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when intraoperative complexity (extensive debridement, dense adhesions, prolonged operative time) significantly increases work. |
23 | Unusual anesthesia |
