Cystoscopy CPT Codes Decoded - A Coder’s Guide to Accuracy

The most commonly used CPT code for a standard cystoscopy (a scope used to examine the bladder) is 52000, Cystourethroscopy (separate procedure). This covers a diagnostic cystoscopy without any additional procedures, and it’s the starting point for many urology claims.

If a surgery is performed during the cystoscopy, you must report 52204, Cystourethroscopy with biopsy. This is different from a simple exam and should be coded accurately to reflect the added work and reimbursement value.

In most cases, you can’t bill them together unless done on different sides (unilateral/bilateral) or with clear medical necessity. For cystoscopy with ureteroscopy, codes like 52352–52356 may apply. Always check for NCCI edits or bundling rules before submitting.

For ureteral stent insertion, use 52332. If the stent is removed via cystoscopy, use 52310. These codes are often misunderstood and lead to denials if not coded precisely based on the technique used.

Many denials happen because:

• The wrong CPT code is selected (e.g., 52000 vs. 52204)
• Insufficient documentation of what was done during the procedure
• Bundled services were billed separately
