    ICD-10-CM Code For Abscess Of Anal And Rectal Regions: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K61 includes perianal, perirectal, rectal, and anal canal abscesses and related anorectal infectious collections such as pilonidal and ischiorectal abscesses. These ICD-10-CM diagnosis codes are used to document acute localized infections of the anal and rectal regions, capturing anatomical site, extent of involvement, and any associated fistula or recurrent disease. Accurate coding within the ICD-10-CM K61 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.
