CPT® Code 51700

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.
