ICD-10 Code K62.89 – Other specified diseases of anus and rectum (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K62.89 – Other specified diseases of anus and rectum
What it is
K62.89 is used for disorders of the anus or rectum that are documented but do not fit a more specific ICD-10-CM diagnosis. Use it when the provider names a distinct condition, but no exact code is available.
Clinical signs
Clinical features vary; refer to documentation. Findings may include anorectal pain, bleeding, discharge, irritation, or a localized lesion, depending on the underlying condition.
When to use this code
Use K62.89 when the record clearly identifies an anus or rectum disorder, yet the documentation does not support a more specific code. It is also appropriate when the provider states “other specified” or describes an unusual anorectal condition not indexed elsewhere.
Confirm the site is the anus or rectum and that the diagnosis is not better captured by another code. If the chart is vague, check documentation before assigning this code.
Do not use for
Do not use K62.89 for general symptoms without a documented diagnosis, or for conditions with their own specific ICD-10-CM code. Check documentation if the record suggests hemorrhoids, fissure, abscess, or malignancy.
Coding tip
Look for the provider’s exact wording and code the most specific anorectal diagnosis supported by the note.
