ICD-10 Code K62.8 – Other specified diseases of anus and rectum (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K62.8 – Other specified diseases of anus and rectum
What it is
K62.8 is used for anorectal conditions that affect the anus or rectum but do not fit a more specific ICD-10-CM diagnosis. It is a residual code, so you should confirm the documented condition and rule out a better-defined option.
Clinical signs
Clinical features vary; refer to documentation. Patients may have anorectal pain, bleeding, discharge, irritation, or abnormal exam findings, but the exact diagnosis is not otherwise specified in the record.
When to use this code
Use K62.8 when the provider documents a specific disorder of the anus or rectum that has no dedicated code in ICD-10-CM. It may apply after evaluation notes a named condition, but the index or tabular list directs you here. If the chart is vague, check documentation before assigning it.
Do not use for
Do not use K62.8 when a more specific anorectal diagnosis is documented, such as hemorrhoids, fissure, abscess, or prolapse. Do not use it for nonspecific symptoms alone; code the symptom if no condition is established.
Coding tip
Search the Alphabetic Index and Tabular List first; K62.8 is appropriate only when no more specific code matches the provider’s documented anorectal condition.
