CPT® Code 53621

A urethral stricture in a male is a condition characterized by the narrowing of the urethra, which can occur due to various factors such as infection or trauma. The procedure described by CPT® Code 53621 involves the dilation of this stricture using a specialized technique that employs a filiform and follower. The filiform dilator is a slender, flexible instrument designed to navigate through the urethra, while the follower is a series of threadlike instruments that progressively increase in diameter. This method allows for the gradual expansion of the narrowed urethra, restoring normal urinary flow. There are two primary types of filiform dilators utilized in this procedure. The first type incorporates a filiform wire guide, which is inserted into the urethra, followed by the insertion of followers of increasing size to effectively dilate the stricture. The second type is an integral filiform urethral dilator that simplifies the process by combining the functions of the filiform and follower into a single instrument, thus eliminating the need for multiple followers. It is important to note that CPT® Code 53620 is designated for the initial dilation procedure using a filiform and follower, while CPT® Code 53621 is specifically used for subsequent dilation procedures.
