🏥CPT 52310: Cystourethroscopy with Removal of Foreign Body or Stone

Code Definition

• Descriptor: cystourethroscopy, with removal of foreign body, calculus, or ureteral stent from urethra or bladder; simple.
• Clinical Context: This procedure involves inserting a cystoscope into the urethra and bladder to identify and remove a foreign object (e.g., a retained suture, self-inserted object) or a stone/calculus located in the bladder or urethra. It also covers the removal of an indwelling ureteral stent if a cystoscope is required to grasp and pull it out.

Global Period & RVU

• Global Period: 000 Days (Endoscopic/Minor Procedure).
  • Billing Note: Because the global period is 0 days, you generally cannot bill an E/M visit (e.g., 99213) on the same day unless there is a significant, separately identifiable reason unrelated to the procedure (Modifier 25).
• Work RVU: Approximately 2.00 - 2.20 (varies slightly by year/location).

Assistant Surgeon Status

• Payable: No.
• Explanation: Medicare and most commercial payers assign this code an assistant surgery indicator of “0”, meaning the concept of an assistant surgeon does not apply. The procedure is typically performed by a single surgeon.

Critical Coding Rules (NCCI & “Separate Procedure”)

• “Separate Procedure” Designation:
  • CPT 52310 is designated as a “separate procedure”.
  • Rule: It should not be reported if it is performed during the same operative session as a more comprehensive procedure on the same anatomical site (urethra/bladder).
  • Example: If the surgeon performs a TURP (52601) or a Cystolitholapaxy (52317), the removal of small stones or foreign bodies (52310) is considered integral and bundled. You cannot bill 52310 separately.
• Stent Removal:
  • Use 52310 if the surgeon uses a cystoscope to grasp and remove a stent.
  • If the stent is removed via a string pulling (without a scope) or simply pulling a Foley, do not use this code. Use an E/M code instead.
• Inclusives: Includes the diagnostic cystoscopy (52000) and any local anesthesia or bladder irrigation.
• Mutually Exclusive: Cannot be billed with 52315 (complicated removal) for the same session. If a stent is removed at the same time as a more complex procedure (like a lithotripsy 52353), the stent removal is often considered bundled unless it is the primary reason for the procedure.

Common Associated Diagnoses (ICD-10)

• N21.0: Calculus in bladder (Bladder stone).
• T19.0XXA: Foreign body in urethra, initial encounter.
• T19.1XXA: Foreign body in bladder, initial encounter.
• Z46.6: Encounter for fitting and adjustment of urinary device (often used for routine stent removal).
• T83.192A: Mechanical complication of other urinary catheter and device (if stent is migrated/calcified).

Documentation Checklist

• Technique: Did the provider use a cystoscope? (Required for 52310).
• Complexity: Was the stone/object removed “simply” (e.g., basket extraction)?
  • If the stone had to be fragmented/crushed first (lithotripsy), look to codes 52317 or 52318 instead.
• Site: Confirmation that the object was in the urethra or bladder, not the ureter.

Key Distinctions:

• Simple vs. Complicated (52310 vs. 52315): * 52310 (Simple): Removal of a stone or an easily accessible object (like a stent) using standard grasping forceps.

  • 52315 (Complex): Removal that requires specialized equipment, is impacted, or is encrusted with minerals (common with long-term stents) requiring extra effort to dislodge.

• Calculus Location: If the stone is in the ureter and requires the scope to go past the bladder into the ureter, you should look at codes 52320 or 52352, as 52310 is limited to the bladder and urethra.

• Stent Removal: If removing a ureteral stent using a cystoscope, 52310 is the standard code used by urologists.
