About coding human papillomavirus screening
The ICD-10-CM code for human papillomavirus screening is Z11.51 (Encounter for screening for human papillomavirus (HPV)).
Within Z11.5 (encounter for screening for other viral diseases), Z11.51 is specifically for encounter for screening for human papillomavirus (HPV). Related codes cover COVID-19 (Z11.52) 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.
