Atypical squamous cells of undetermined significance on cytologic smear of cervix (ASC-US)
ICD-10 R87.610 is a billable code used to indicate a diagnosis of atypical squamous cells of undetermined significance on cytologic smear of cervix (asc-us).
Atypical squamous cells of undetermined significance (ASC-US) is a finding on a cervical cytology smear that indicates the presence of abnormal squamous cells that do not meet the criteria for a definitive diagnosis of squamous intraepithelial lesion (SIL). This finding is significant as it may suggest the presence of human papillomavirus (HPV) infection or other underlying conditions, but it does not provide a clear indication of malignancy. ASC-US is often a result of transient HPV infection, which is common in sexually active women. The clinical significance of ASC-US lies in the need for further evaluation, typically through HPV testing or a follow-up Pap smear, to determine the appropriate management. The diagnosis is crucial as it guides the clinician in deciding whether to monitor the patient or to initiate further diagnostic procedures, such as colposcopy. The interpretation of ASC-US requires careful consideration of the patient's history, risk factors, and the context of the cytological findings.
Documentation should include patient history, risk factors for cervical cancer, and follow-up plans based on cytology results.
Routine screening in women aged 21-65, follow-up after abnormal Pap results.
Consideration of patient's HPV vaccination status and sexual history is essential for accurate coding.
Acute care documentation should include the reason for the cytology test and any immediate concerns related to the findings.
Patients presenting with abnormal bleeding or pelvic pain who require urgent evaluation.
Emergency settings may require expedited follow-up plans and clear documentation of findings.
Used when performing a Pap smear that results in ASC-US.
Documentation of the cytology report and follow-up recommendations.
Ensure that the procedure is linked to the diagnosis of ASC-US.
ASC-US stands for atypical squamous cells of undetermined significance, indicating abnormal cervical cells that require further evaluation.
Management typically involves follow-up HPV testing and repeat Pap smears to determine the need for further intervention.
ASC-US is not a definitive sign of cancer but indicates the need for further evaluation to rule out high-grade lesions.
