Urology is the medical specialty that focuses on surgical and medical diseases of the male and female urinary system (kidneys, ureters, urinary bladder, and urethra) and the male reproductive organs. Codes for procedures to diagnose and treat urinary system disorders are found in the Surgery section of the Current Procedural Terminology (CPT®) code set (50010-53899). This course reviews the basic anatomy of the urinary system as part of the foundational knowledge needed for appropriate reporting of these CPT codes. This course also introduces the learner to the format of the codes, pertinent guidelines, and common modifiers used with the urinary system procedure codes in the CPT code set.
