ICD-10 Code K62 – Other diseases of anus and rectum (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K62 – Other diseases of anus and rectum
What it is
K62 is a broad code for conditions affecting the anus or rectum that are not classified elsewhere. It is used when documentation names a specific anorectal disorder without a more precise ICD-10 option.
Clinical signs
Clinical features vary; refer to documentation. Common anorectal findings may include pain, bleeding, discharge, itching, or a visible lesion, but you should code only what is clearly documented.
When to use this code
Use K62 when the provider documents an anorectal disease and no more specific code applies. It may fit nonspecific rectal or anal disorders that are not better described by another ICD-10 category. If the record identifies a named condition elsewhere in ICD-10, choose that code instead.
Do not use for
Do not use K62 for hemorrhoids, constipation, or inflammatory bowel disease unless the documentation supports a separate anorectal diagnosis. Check documentation if the condition is actually a symptom, procedure finding, or a more specific disease.
Coding tip
Read the full note for the exact anorectal diagnosis and code the most specific documented condition first.
