Atyp squam cell not excl hi grd intrepith lesn cyto smr crvx

This code signifies a cervical cytology result indicating atypical squamous cells where a high-grade squamous intraepithelial lesion (HSIL) cannot be definitively ruled out. It represents an abnormal Pap test finding that is more concerning than atypical squamous cells of undetermined significance (ASC-US) but not yet diagnostic of HSIL.

Use this code when a pathology report for a cervical cytologic smear explicitly states "Atypical Squamous Cells, Cannot Exclude HSIL" (ASC-H). This result typically prompts further diagnostic evaluation, such as colposcopy and biopsy, to determine the presence and grade of cervical dysplasia.

• Do not use this code for ASC-US or definitive HSIL; those have separate codes.
• This code represents a finding, not a definitive diagnosis of HSIL.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, such as for follow-up or further diagnostic procedures.
