Other diseases of anus and rectum (K62) ICD-10-CM
The K62 code range covers other diseases of anus and rectum with 14 ICD-10-CM diagnosis codes. 12 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- anal canal
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the K62 range.
Low Anterior Resection Syndrome
Postoperative complication after removal of the RECTUM (low anterior resection surgery or resection surgery to the lower part of the COLON). It includes disordered rectum function, e.g., frequent BOWEL MOVEMENT; FECAL INCONTINENCE; and CONSTIPATION.
Proctitis
INFLAMMATION of the MUCOUS MEMBRANE of the RECTUM, the distal end of the large intestine (INTESTINE, LARGE).
Proctocolitis
Inflammation of the RECTUM and the distal portion of the COLON.
Rectal Prolapse
Protrusion of the rectal mucous membrane through the anus. There are various degrees: incomplete with no displacement of the anal sphincter muscle; complete with displacement of the anal sphincter muscle; complete with no displacement of the anal sphincter muscle but with herniation of the bowel; and internal complete with rectosigmoid or upper rectum intussusception into the lower rectum.
About the K62 Code Range
The K62 ICD-10 code section covers a variety of specific diseases affecting the anus and rectum, addressing conditions such as anal and rectal polyps, prolapse, stenosis, hemorrhage, ulcers, and radiation-induced damage. These codes help precisely identify and classify uncommon or other specified diseases of these areas for diagnosis and treatment.
This section includes K62.0 and K62.1, which refer to anal polyp and rectal polyp, respectively, also known as inflammatory or lymphoid polyps and benign rectal growths. Codes K62.2 and K62.3 describe prolapse conditions, including anal prolapse and the more complex rectal prolapse (proctoptosis). Narrowing of these structures, called stenosis or stricture, is coded under K62.4. The section also covers bleeding problems with K62.5 for hemorrhage of anus and rectum, and K62.6 identifies ulcers, including those caused by infections or chronic inflammation. Radiation-related damage is captured with K62.7 for radiation proctitis. Additional codes classify other specified diseases, such as nontraumatic anal sphincter tears (K62.81), and dysplasia from human papillomavirus infections (K62.82). The broad K62.89 group includes diverse anorectal conditions like infective proctitis and chronic pain syndromes. Finally, K62.9 provides a code for unspecified diseases of the anus and rectum.
