ICD-10 code for Anorectal abscess

The ICD-10-CM code for Anorectal abscess is K61.2 (Anorectal abscess).

Within K61 (abscess of anal and rectal regions), K61.2 is specifically for Anorectal abscess. Related codes cover anal abscess (K61.0), rectal abscess (K61.1), ischiorectal abscess (K61.3), Intrasphincteric abscess (K61.4) and Supralevator abscess (K61.5).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 393 (Other Digestive System Diagnoses with MCC, relative weight 1.5881), DRG 394 (Other Digestive System Diagnoses with CC, relative weight 0.9228), DRG 395 (Other Digestive System Diagnoses without CC/MCC, relative weight 0.6382), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 06 (Diseases and Disorders of the Digestive System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
