Unsatisfactory cytologic smear of cervix

This code indicates that a cervical cytology (Pap test) specimen was inadequate for proper evaluation by the pathologist. This typically means the sample lacked sufficient cellular material, was obscured by blood or inflammation, or was improperly collected or preserved, preventing a definitive diagnostic interpretation.

Apply this code when the pathology report explicitly states the cervical smear is "unsatisfactory," "inadequate," or "nondiagnostic" due to issues with the specimen quality. Documentation must clearly indicate the reason for the unsatisfactory result, such as insufficient squamous cells or obscuring factors.

• Do not use this code for smears that are "satisfactory but limited by" (e.g., absence of endocervical cells), as these are considered adequate for interpretation.
• This code is often a primary diagnosis, indicating the need for a repeat Pap test.
• Ensure the pathology report specifically uses terminology consistent with an "unsatisfactory" smear, not just a suboptimal one.
