Official Description

Bladder irrigation, simple, lavage and/or instillation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 51700 refers to a procedure known as bladder irrigation, which can involve either a simple lavage or an instillation of fluid into the bladder. In this context, a lavage procedure entails both the instillation and subsequent removal of fluid, while an instillation procedure may involve only the introduction of fluid without removal. During this procedure, a catheter is carefully inserted into the bladder to facilitate the process. If a lavage is being conducted for the purpose of bladder irrigation, a sterile solution, typically normal saline, is instilled into the bladder and then subsequently removed. This lavage technique is primarily utilized to prevent or treat the formation of blood clots within the bladder, which can occur due to various medical conditions. Additionally, instillation may involve the use of normal saline or specific medications, such as antibiotics, which can be administered directly into the bladder. In certain cases, antibiotic instillation may be delivered over an extended period as a continuous drip, allowing for sustained therapeutic effects. Upon completion of the lavage and/or instillation procedure, the catheter may either be removed from the bladder or left in place to facilitate the drainage of urine, depending on the clinical situation and the physician's discretion.

1. Indications

The procedure described by CPT® Code 51700 is indicated for various clinical scenarios where bladder irrigation is necessary. The following conditions may warrant the performance of this procedure:

  • Prevention of Blood Clots The procedure is performed to help prevent the formation of blood clots in the bladder, which can occur due to certain medical conditions or following surgical interventions.
  • Treatment of Existing Blood Clots Bladder irrigation may be indicated for the treatment of existing blood clots within the bladder, aiding in their removal and improving bladder function.
  • Administration of Medications The instillation of medications, such as antibiotics, into the bladder may be necessary for treating infections or other bladder-related conditions.

2. Procedure

The procedure for bladder irrigation as described by CPT® Code 51700 involves several key steps that ensure effective lavage and/or instillation. Each step is crucial for achieving the desired therapeutic outcome:

  • Step 1: Catheter Insertion The first step involves the careful insertion of a catheter into the bladder. This is typically done using sterile techniques to minimize the risk of infection. The catheter serves as the conduit for fluid instillation and removal.
  • Step 2: Instillation of Fluid Once the catheter is in place, a sterile solution, usually normal saline, is instilled into the bladder. This fluid may also include medications if indicated. The volume and type of fluid used will depend on the specific clinical situation and the physician's judgment.
  • Step 3: Lavage Process If a lavage is being performed, the instilled fluid is then allowed to dwell in the bladder for a specified period before being removed. This process helps to wash out any debris, blood clots, or other unwanted materials from the bladder.
  • Step 4: Fluid Removal After the lavage period, the fluid is carefully removed from the bladder through the catheter. This step is essential for clearing the bladder of any clots or irritants that may have been present.
  • Step 5: Catheter Management Following the completion of the lavage and/or instillation, the catheter may either be removed or left in place. If left in place, it will facilitate the drainage of urine, depending on the patient's needs and the physician's assessment.

3. Post-Procedure

After the bladder irrigation procedure is completed, patients may require monitoring for any potential complications, such as infection or bleeding. If the catheter is left in place, care must be taken to ensure proper catheter maintenance to prevent obstruction or infection. Patients may also be advised on signs and symptoms to watch for, such as changes in urine color, pain, or difficulty urinating, which should be reported to their healthcare provider. Follow-up appointments may be necessary to assess the effectiveness of the procedure and to determine if further treatment is required.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
