Anorectal abscess

This code signifies a localized collection of pus within the tissues surrounding the anus and rectum. It typically results from an infection of the anal glands, leading to inflammation and suppuration in the perianal or perirectal space. Patients often present with severe pain, swelling, and tenderness in the affected area.

Use this code when documentation clearly indicates a diagnosis of an anorectal abscess, without further specification of its exact location (e.g., perianal, ischiorectal). This diagnosis is often supported by physical examination findings of a tender, fluctuant mass, sometimes with associated fever or chills.

• Do not use this code if a more specific anatomical location of the abscess (e.g., perianal, ischiorectal, supralevator) is documented; use the more precise K61 subcategory code.
• Consider sequencing this code as the primary diagnosis if the abscess is the main reason for the encounter and treatment.
• Ensure documentation differentiates between an abscess and a fistula; K60 codes are for anal and rectal fistulae.
