CPT® Code 46705

Anoplasty, as described by CPT® Code 46705, refers to a surgical procedure specifically designed to address anal strictures in infants. Anal strictures can either be congenital, meaning they are present at birth, or acquired, which typically results from various forms of trauma or injury to the anal canal. Acquired anal strictures may develop due to scar tissue formation that constricts the anal canal, leading to significant difficulties in passing stool. This scarring can occur as a result of several factors, including tears, radiation therapy for cancers located in the perianal area, or trauma from previous surgical interventions. In contrast, congenital anal strictures, also known as anal stenosis, are structural abnormalities that exist from birth. During the anoplasty procedure, the anal mucosa is carefully incised to expose the underlying scar tissue. The surgeon then incises the scar tissue within the anal canal or anal sphincter to alleviate the stricture, effectively widening the anal canal to restore normal function. Following the incision of the scar tissue, the overlying tissues are meticulously repaired in layers to ensure proper healing and function. It is important to note that CPT® Code 46705 is specifically designated for use in infants, while CPT® Code 46700 is applicable for the repair of anal strictures in adults.
