Clinical Context: Medium Tumor Size Threshold
CPT 52235 captures fulguration and/or resection of medium bladder tumors measuring 2.0 to 5.0 cm. The size range (2.0-5.0 cm) is the critical distinction from 52234 (small 0.5-2.0 cm) and 52240 (large >5.0 cm). Documentation must explicitly state the tumor size falls within the 2.0-5.0 cm range to support 52235. If size is not documented or is at the boundary (exactly 2.0 cm), query the provider for clarification.

🔍 Code Description
CPT 52235 classifies cystourethroscopy with fulguration (including cryosurgery or laser surgery) and/or resection of medium bladder tumor(s) (2.0 to 5.0 cm). This code represents transurethral resection of bladder tumor (TURBT) for medium-sized tumors and is the workhorse code for most therapeutic endoscopic bladder cancer procedures.
The procedure involves passing a resectoscope through the urethra to visualize the bladder, identifying medium-sized tumors (2.0-5.0 cm), and resecting them using electrocautery (loop electrode), laser, or cryotherapy. Fulguration of the resection base is typically performed to achieve hemostasis. This code is commonly used for muscle-invasive and non-muscle invasive bladder cancer, large papillary tumors, and sessile lesions requiring complete resection.

Size Documentation Is Critical
The only difference between 52234, 52235, and 52240 is tumor size: 0.5-2.0 cm vs. 2.0-5.0 cm vs. >5.0 cm. If the operative note does not document exact tumor size, the coder cannot definitively select between these codes. A CDI query requesting exact tumor size (in cm) is appropriate and necessary for accurate coding. Note: A tumor exactly 2.0 cm could be coded as either 52234 or 52235 depending on provider preference, but consistency within the practice is recommended.

❌ Excludes
Excludes 1 — Cannot Be Coded Simultaneously with 52235
| Code | Description | Note |
|---|---|---|
| 52000 | Cystourethroscopy (separate procedure) | Diagnostic cystoscopy is bundled into 52235; never bill together |
| 52204 | Cystourethroscopy with biopsy(s) | Biopsy bundles into 52235 when performed at same session |
| 52224 | Cystourethroscopy with fulguration of minor (<0.5cm) lesion(s) | Mutually exclusive — select the code that best describes the tumor size |
| 52234 | Cystourethroscopy with fulguration/resection of small bladder tumor(s) (0.5-2.0cm) | Mutually exclusive — different size category |
| 52240 | Cystourethroscopy with fulguration/resection of large bladder tumor(s) | Mutually exclusive — different size category |
Excludes 1 Violation Risk
The most common coding error is billing 52000 (diagnostic cystoscopy) with. NCCI edits bundle 52000 into 52235. If both diagnostic and therapeutic cystoscopy are performed, only 52235 is reported. Another common error is using the wrong size-based code — always verify exact tumor size in the operative note. Multiple tumors of different sizes in the same session: bill the code for the largest tumor size; do not bill multiple size-based codes.
Excludes 2 — May Be Coded in Addition if Separately Present
| Code | Description | Note |
|---|---|---|
| 51720 | Bladder instillation of anticarcinogenic agent | May be separately billable if performed in a distinct session later the same day (e.g., post-op mitomycin instillation in recovery room); append modifier 59 |

CDI Query Trigger — Size Documentation and Multiple Tumors
When the operative note describes a “medium bladder tumor” or “large tumor” without exact measurements, a CDI query should request: “Please specify the size of the bladder tumor in centimeters to support accurate CPT code selection (52234 0.5-2.0cm, 52235 2.0-5.0cm, 52240 >5.0cm).” If multiple tumors of different sizes are resected, document the size of each tumor; bill the code for the largest tumor size.
Common Clinical Indications
- Non-muscle invasive bladder cancer (NMIBC): High-grade Ta, T1 tumors
- Muscle-invasive bladder cancer (MIBC): T2 tumors requiring complete resection for staging
- Recurrent papillary tumors: Medium-sized recurrent papillary urothelial carcinoma
- Sessile lesions: Broad-based tumors requiring deep resection
- Carcinoma in situ (CIS): Extensive CIS requiring fulguration/resection
- Hematuria: Large bleeding tumor as source of gross hematuria

💊 Coding Scenarios and Examples
Scenario 1 — Outpatient/ASC: Primary TURBT for Medium Bladder Tumor
Clinical Vignette: A 68-year-old male presents with gross hematuria. CT urogram shows a 3.5cm filling defect in the left lateral wall of the bladder. Cystoscopy confirms a 3.5cm papillary tumor. The urologist performs complete transurethral resection using a loop electrode, followed by fulguration of the base. Specimen sent to pathology. Patient tolerates procedure well and is discharged same day.
CPT Codes:
- 52235 — Cystourethroscopy with fulguration/resection of medium bladder tumor(s) (2.0-5.0cm) (primary procedure)
ICD-10-CM:
- C67.2 — Malignant neoplasm of lateral wall of bladder (primary diagnosis)
- R31.0 — Gross hematuria (secondary — presenting symptom)
Note: 52000 and 52204 are NOT billed separately. If E/M service was significant and separately identifiable, bill with modifier 25.
Scenario 2 — Outpatient: Multiple Tumors of Different Sizes
Clinical Vignette: A 75-year-old female with history of NMIBC presents for surveillance. Cystoscopy reveals three tumors: 1.5cm papillary tumor on the dome, 3.0cm sessile tumor on the posterior wall, and 0.8cm papillary tumor on the right lateral wall. The urologist resects all three tumors and fulgurates the bases.
CPT Codes:
- 52235 — Cystourethroscopy with fulguration/resection of medium bladder tumor(s) (2.0-5.0cm) (primary procedure — bill for largest tumor size)
ICD-10-CM:
- C67.4 — Malignant neoplasm of posterior wall of bladder (primary — largest tumor site)
- C67.1 — Malignant neoplasm of dome of bladder (secondary)
- C67.2 — Malignant neoplasm of lateral wall of bladder (secondary)
- Z85.51 — Personal history of malignant neoplasm of bladder (history)
Note: Only ONE size-based code is billed per session — the code for the largest tumor (52235 for the 3.0cm tumor). Do NOT bill 52234 (for 0.8cm and 1.5cm tumors) in addition to 52235.
Scenario 3 — CDI Query: Ambiguous Tumor Size
Clinical Vignette: Operative note states: “Cystoscopy performed. Large papillary tumor seen on posterior wall. Resected in entirety. Fulgurated.” No specific size documented. Pathology: “High-grade papillary urothelial carcinoma, 4.2cm in greatest dimension.”
Action / Outcome: Coding uncertainty: Cannot determine if 52235 (2.0-5.0cm) or 52240 (>5.0cm) is correct based on operative note alone. Pathology shows 4.2cm (supports 52235), but operative note should document size. CDI query sent to urologist.
Query Response: Provider clarifies: “Tumor measured approximately 4.2cm in greatest dimension, completely resected.”
Corrected CPT Coding:
- 52235 — Cystourethroscopy with fulguration/resection of medium bladder tumor(s) (2.0-5.0cm) (accurate code after CDI clarification)
⚠️ Coding Pitfalls and Tips
| Pitfall or Tip | |
|---|---|
| ❌ | Billing 52000 with 52235. Diagnostic cystoscopy is bundled into 52235. Never bill 52000 and 52235 for the same session. |
| ❌ | Billing 52204 with 52235. Biopsy is bundled into 52235 when performed at same session. Do not bill 52204 separately. |
| ❌ | Billing multiple size-based codes. Only ONE size-based TURBT code (52224/52234/52235/52240) is billed per session. Bill the code for the largest tumor. |
| ❌ | Using 52235 without documented size. The 2.0-5.0cm range must be explicitly documented. If size is missing, query the provider. |
| ❌ | Confusing 52214 with 52235. 52214 is for non-tumor fulguration at specific sites. 52235 is for medium bladder tumors (2.0-5.0cm). |
| ✅ | Modifier -25 for E/M. A significant, separately identifiable E/M service on the same day may be billed with modifier -25. |
| ✅ | Modifier -59 for distinct sites. If fulguration is performed at a completely separate anatomical site from another procedure, modifier -59 may apply. |
| ✅ | Modifier -22 for increased complexity. If the procedure requires significantly greater work (e.g., very large 4.9cm tumor near ureteral orifice, requiring ureteral catheterization), modifier -22 may be appended with detailed supporting documentation. |
| ✅ | Document exact size in cm. Always document tumor size in centimeters (not “medium,” “large,” “walnut-sized”) to support accurate code selection. |
| ✅ | Bill 51720 separately if distinct session. Post-operative bladder instillation of anticarcinogenic agent (e.g., mitomycin) may be separately billable with modifier -59 if performed in a distinct session later the same day (e.g., recovery room, not in OR). |
