About Z01.42
Z01.42 is the ICD-10-CM diagnosis code for encounter for cervical smear to confirm findings of recent normal smear following initial abnormal smear. It belongs to category Z01 (encounter for other special examination without complaint, suspected or reported diagnosis), block Z00-Z13 (persons encountering health services for examinations) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within Z01.4 (encounter for gynecological examination), Z01.42 is specifically for encounter for cervical smear to confirm findings of recent normal smear following initial abnormal smear. Related codes cover routine gynecological examination (Z01.41).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as V72.32 (encounter for Papanicolaou cervical smear to confirm findings of recent normal smear following initial abnormal smear).
