Anal prolapse

This code represents a condition where the rectal mucosa, or the entire rectal wall, protrudes through the anus. This prolapse can be partial (mucosal) or full-thickness, and it is distinct from hemorrhoids or intussusception. Patients typically present with a mass protruding from the anus, often accompanied by discomfort, bleeding, or fecal incontinence.

Use this code when documentation clearly indicates a diagnosis of anal prolapse, also known as rectal prolapse. This applies to both partial and complete prolapse of the rectum through the anal opening. Supporting documentation would include physician notes detailing the physical examination findings of a prolapsed rectum.

• Differentiate carefully between anal prolapse and hemorrhoids; these are distinct conditions.
• Do not confuse with intussusception, which is the telescoping of one part of the intestine into another.
• If the prolapse is due to a specific underlying condition, consider sequencing the underlying condition first, if applicable, according to ICD-10-CM guidelines.
