ICD-10 Code K64.3 – Fourth degree hemorrhoids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K64.3 – Fourth degree hemorrhoids
What it is
K64.3 identifies fourth degree hemorrhoids, which are prolapsed hemorrhoids that cannot be manually reduced. Use this code when the documentation clearly states the hemorrhoids are fourth degree.
Clinical signs
Clinical features typically include persistent prolapse and symptoms such as rectal bleeding, pain, itching, or irritation. Clinical features vary; refer to documentation.
When to use this code
Use K64.3 when the provider documents fourth degree hemorrhoids or an equivalent description, such as irreducible prolapsed hemorrhoids. Apply it for confirmed internal hemorrhoids at this severity, not for generic hemorrhoids without degree specified.
If the note only says hemorrhoids, check documentation for the degree before coding. If the record describes a different hemorrhoid type or severity, select the more specific documented code.
Do not use for
Do not use K64.3 for first-, second-, or third-degree hemorrhoids, or for hemorrhoids without documentation of irreducibility. Check documentation if the degree is unclear.
Coding tip
Look for the words “fourth degree,” “irreducible,” or “cannot be manually reduced” before assigning K64.3.
