R85.615

Unsatisfactory cytologic smear of anus

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

Code Description

ICD-10 R85.615 is a billable code used to indicate a diagnosis of unsatisfactory cytologic smear of anus.

Key Diagnostic Point:

The code R85.615 refers to an unsatisfactory cytologic smear of the anus, which indicates that the sample collected for cytological examination was inadequate for diagnostic purposes. This may occur due to insufficient cellular material, poor sample quality, or contamination. An unsatisfactory smear can hinder the detection of abnormalities such as dysplasia or malignancy, necessitating repeat testing. Common symptoms prompting a cytologic smear may include anal bleeding, pain, or changes in bowel habits. The clinical context often involves screening for anal cancer, particularly in high-risk populations such as individuals with a history of human papillomavirus (HPV) infection or those with immunocompromised states. The diagnostic approach typically involves a thorough clinical history, physical examination, and possibly imaging studies to assess for underlying conditions. If the smear is deemed unsatisfactory, clinicians must ensure appropriate follow-up and repeat testing to ensure patient safety and accurate diagnosis.

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Documentation should include the reason for the cytologic smear, patient history, and any relevant symptoms. Follow-up plans must be clearly outlined.

Common Clinical Scenarios

Patients presenting with anal discomfort, bleeding, or a history of HPV requiring screening.

Billing Considerations

Consideration of patient demographics and risk factors for anal cancer is crucial for accurate coding.

Emergency Medicine

Documentation Requirements

Acute care documentation must include the presenting symptoms, any immediate interventions, and plans for follow-up testing.

Common Clinical Scenarios

Patients with acute anal pain or bleeding requiring urgent evaluation.

Billing Considerations

Emergency settings may require expedited documentation and coding due to the nature of patient presentations.
