ICD-10 Code K62.7 – Radiation proctitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K62.7 – Radiation proctitis
What it is
K62.7 identifies inflammation or injury of the rectum caused by prior radiation therapy. Use it when documentation shows rectal complications related to radiation exposure.
Clinical signs
Clinical features may include rectal pain, bleeding, mucus discharge, urgency, or bowel habit changes. Findings can be acute or chronic; refer to documentation for the specific presentation.
When to use this code
Use K62.7 when the provider documents radiation proctitis, radiation injury of the rectum, or similar wording tied to previous radiotherapy. It is appropriate when the rectal condition is the focus of care or a documented complication. Check documentation if the note does not clearly link the rectal problem to radiation.
Do not use for
Do not use this code for nonspecific proctitis without a radiation cause. Do not assign it if the record describes another anorectal disorder or if the radiation link is not documented.
Coding tip
Always confirm the provider connects the rectal inflammation to prior radiation before assigning K62.7.
