R85.614

Cytologic evidence of malignancy on smear of anus

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R85.614 is a billable code used to indicate a diagnosis of cytologic evidence of malignancy on smear of anus.

Key Diagnostic Point:

Cytologic evidence of malignancy on smear of anus refers to the detection of cancerous cells in a sample obtained from the anal region. This finding is typically identified through a Pap smear or similar cytological examination, which is performed to screen for anal cancer or precancerous conditions. Symptoms may include anal bleeding, pain, or changes in bowel habits, although some patients may be asymptomatic. The presence of malignant cells indicates a need for further diagnostic evaluation, which may include imaging studies or biopsy to confirm the diagnosis and assess the extent of the disease. Common causes of this finding include human papillomavirus (HPV) infection, which is a significant risk factor for anal cancer, as well as other factors such as immunosuppression, smoking, and a history of anal or cervical dysplasia. Early detection is crucial for effective management and treatment of anal malignancies.
