Z11.52Encounter for screening for COVID-19

Z11.52 is the ICD-10-CM diagnosis code for encounter for screening for COVID-19. It belongs to category Z11 (encounter for screening for infectious and parasitic diseases), 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 Z11.5 (encounter for screening for other viral diseases), Z11.52 is specifically for encounter for screening for COVID-19. Related codes cover human papillomavirus (HPV) (Z11.51) and other viral diseases (Z11.59).

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 not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It was added in FY2021, effective October 1, 2020.
