ICD-10 Code K61.5 – Supralevator abscess (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K61.5 – Supralevator abscess
What it is
Supralevator abscess is a deep anorectal abscess located above the levator ani muscle. It represents a serious, localized infection in the pelvic or perirectal space.
Clinical signs
Patients may have deep rectal or pelvic pain, fever, and tenderness on examination. Clinical features vary; refer to documentation for the abscess location and any associated anorectal infection.
When to use this code
Use K61.5 when the provider documents a supralevator abscess specifically. Apply it for imaging-confirmed or surgically confirmed deep abscesses above the levator ani, including perirectal or pelvic extension when documented as supralevator.
Do not substitute a more general anorectal abscess code if the record identifies this anatomic site. If the note only says “perianal abscess” or “rectal abscess,” check documentation before coding.
Do not use for
Do not use this code for superficial perianal abscesses, fistulas without abscess, or nonspecific anorectal infections. Check documentation if the abscess location is not clearly stated.
Coding tip
Code the exact abscess location from the provider’s documentation; if supralevator is not explicitly stated, query before assigning K61.5.
