Rectal abscess

This code signifies a localized collection of pus within the tissues of the rectum. It typically results from an infection of the anal glands, leading to inflammation and suppuration. Patients often present with severe rectal pain, swelling, and sometimes fever.

Use this code when documentation clearly indicates an abscess located specifically within the rectal wall or perirectal tissues. Supporting documentation should include physician notes detailing the location of the abscess, symptoms, and diagnostic findings such as physical examination or imaging.

• Differentiate carefully between a rectal abscess and an ischiorectal abscess, as these are Excludes1 conditions.
• Ensure the documentation specifies "rectal" to avoid confusion with other perianal or anal abscesses.
• Consider additional codes for any associated conditions, such as Crohn's disease, if documented as causative.
