CPT® Code 51605

The CPT® Code 51605 refers to an injection procedure involving the placement of a chain for contrast and/or chain urethrocystography. This procedure entails the introduction of a specialized tube that contains a beaded chain and a catheter through the urethra. Once the tube is in place, a contrast agent is injected to enhance the visibility of the urinary tract during imaging. The procedure is designed to obtain radiographs, which are separate and reportable, to evaluate the anatomy and function of the bladder and urethra. Chain cystourethrography was primarily utilized to assess stress incontinence in women by evaluating urethral hypermobility and the extent of bladder descent. However, it is important to note that this diagnostic method has largely been supplanted by more advanced techniques, such as video urodynamic studies, which provide a more comprehensive analysis of urinary function.
