ICD-10 Code K51.214 – Ulcerative (chronic) proctitis with abscess (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K51.214 – Ulcerative (chronic) proctitis with abscess
What it is
K51.214 identifies chronic ulcerative inflammation limited to the rectum, with an associated abscess. Use it when documentation shows ulcerative proctitis and a rectal or perirectal abscess.
Clinical signs
Typical findings include rectal pain, urgency, bleeding, and mucus discharge. Clinical features vary; refer to documentation for evidence of abscess, such as localized tenderness, drainage, or imaging confirmation.
When to use this code
Use this code when the provider documents ulcerative chronic proctitis and also notes an abscess related to the condition. It may appear in gastroenterology, colorectal, or inpatient records when both diagnoses are clearly linked. Check documentation if the abscess site is not specified.
Do not use for
Do not assign this code for ulcerative colitis without rectal involvement or for proctitis without abscess. Do not use it when the abscess is unrelated to the ulcerative disease; check documentation.
Coding tip
Code the abscess only when the record supports a direct association with ulcerative proctitis.
