ICD-10 Code K64.1 – Second degree hemorrhoids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K64.1 – Second degree hemorrhoids
What it is
Second degree hemorrhoids are internal hemorrhoids that prolapse during straining and then reduce on their own. Use this code when the documentation clearly identifies second-degree disease.
Clinical signs
Common findings include intermittent rectal bleeding and prolapse with bowel movements that returns spontaneously. Clinical features vary; refer to documentation.
When to use this code
Use K64.1 when the provider documents second-degree internal hemorrhoids, especially if the note describes prolapse that reduces without manual help. It also fits when the diagnosis is stated without conflicting detail. If the record only says “hemorrhoids” or does not specify degree, check documentation.
Do not use for
Do not use this code for first-, third-, or fourth-degree hemorrhoids. Avoid it if the documentation refers only to external hemorrhoids or another anorectal condition.
Coding tip
Code the documented degree exactly; if the degree is missing, query the provider before assigning K64.1.
