CPT 00912: Anesthesia for Transurethral Bladder Tumor Excision
CPT code 00912 identifies anesthesia services for transurethral excision of one or more bladder tumors. This code matters nationally because transurethral bladder tumor procedures are common urologic interventions that require specialized anesthesia care to manage patient safety, airway and hemodynamic stability, and anesthesia depth during endoscopic intravesical surgery. Appropriate use of this code affects hospital and ambulatory surgical center billing, anesthesia resource allocation, and payer coverage determinations.
Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise overview of what the code represents, the typical clinical context and site of service, and links to related anesthesia procedure codes. The publication summarizes common billing modifiers and associated anesthesia provider taxonomies, outlines related CPT anesthesia entries for transurethral procedures, and highlights typical diagnostic pairings used in claims where available.
This report is intended for billing managers, anesthesia providers, and revenue cycle professionals seeking a clear reference on clinical scope and coding relationships for CPT code 00912. Data not available in the input is explicitly noted where applicable.

Billing Code Overview
CPT code 00912 describes anesthesia services provided for a patient undergoing excision of one or more tumors within the bladder performed through the urethra. This procedure is typically a transurethral bladder tumor excision and requires anesthesia management for endoscopic removal of bladder lesions.
Service type: Anesthesia for transurethral bladder tumor excision
Typical site of service: Ambulatory surgical center or hospital operating room, with the procedure performed via the urethra using endoscopic instruments for tumor excision.
Clinical & Coding Specifications
Clinical Context
A 68-year-old male presents with painless gross hematuria and a cystoscopic evaluation reveals one or more papillary lesions within the urinary bladder consistent with urothelial tumors. The patient is scheduled for transurethral resection of bladder tumor(s) (TURBT) under monitored anesthesia care or general endotracheal anesthesia. Preoperative assessment is performed by the anesthesiology team, including review of comorbidities, allergies, airway evaluation, and medication reconciliation. Perioperative workflow includes placement of standard ASA monitors, intravenous access, induction of anesthesia (MAC, regional block, or general anesthesia as clinically indicated), intraoperative management of hemodynamics and airway, surgical transurethral resection via the urethra with cystoscopic visualization, urinary catheter placement as needed, and recovery in the PACU with postoperative pain and bleeding surveillance. The anesthetic choice is influenced by tumor burden, expected case duration, patient comorbidities, and potential need for conversion to more invasive airway techniques. Documentation includes the anesthesia start and end times, agents used, airway management, intraoperative events, and immediate postoperative status.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when anesthesia required substantially greater work due to complexity, documented and supported by operative/anesthesia note. |
23 | Unusual anesthesia | Use when general anesthesia is medically necessary for a procedure normally done with local or MAC and is documented. |
50 | Bilateral procedure | Use if identical procedures performed on both sides when anatomically applicable (limited applicability for bladder procedures). |
52 | Reduced services | Use when the anesthesia service was partially reduced or abbreviated, documented with rationale. |
53 | Discontinued procedure | Use when the procedure is terminated due to extenuating circumstances after anesthesia initiated. |
55 | Postoperative management only | Use when anesthesia provider only furnishes postoperative care, not intraoperative management. |
62 | Two surgeons | Use when two surgeons are required and documented, affecting anesthesia complexity. |
78 | Return to OR for related procedure during global period | Use when patient returns to operating room for a complication of the original procedure requiring additional anesthesia. |
AA | Anesthesia by anesthesiologist | Use when services are personally performed by a physician anesthesiologist (per payer requirements). |
QK | Medical direction of two, three, or four CRNAs by an anesthesiologist | Use when the anesthesiologist medically directs multiple CRNAs as documented. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Physician anesthesiologists who direct or personally provide anesthesia services for TURBT procedures. |
367500000X | Certified Registered Nurse Anesthetist | CRNAs who may provide anesthesia under direction or supervision depending on state law and facility. |
207RA0401X | Anesthesiology Assistant | Anesthesiology assistants who may participate under physician supervision in the anesthesia plan. |
